Revision as of 03:46, 18 February 2013



As the Enterprise comes under attack on the way to a diplomatic conference on Babel, one of the alien dignitaries is murdered, and Spock's estranged father Sarek is the prime suspect--but he is also deathly ill, and only Spock can save him.




The USS Enterprise arrives in orbit around Vulcan, picking up the last delegation of Vulcans to add to an assortment of ambassadors and dignitaries aboard (including Andorians and Tellarites). The delegates will be attending a conference on Babel to decide the admission of the planet Coridan to the Federation, which is rich in dilithium but poorly defended. As the shuttle of Vulcans arrives, Kirk, Spock, and McCoy greet the Vulcan ambassador to Earth, Sarek, and his Human wife Amanda. Welcoming the ambassador aboard, Kirk offers to have Spock take him and his wife on a tour of the ship, but Sarek coldly asks that someone else give it. Sensing unpleasantness between the two Vulcans, the captain suggests to Spock that, with two hours before the ship leaves orbit, he should beam down to the planet and visit his parents, which Spock insists would be unnecessary, for the ambassador and his wife, in fact, are his parents.

Act One

"Captain's log, stardate 3842.3. We have departed Vulcan for the neutral planetoid code-named Babel. Since it is in our sector, the Enterprise has been assigned to transport ambassadors of Federation planets to this vitally important council. The issues of the council are politically complex, the passengers... explosive."

As Kirk conducts a tour of the ship for the ambassador and his wife, he also discovers roots of estrangement between Spock and his father, springing from Spock's election to attend Starfleet Academy over his father's choice of the Vulcan Science Academy. Kirk voices his support of Spock's choices and his personal friendship with Spock to Amanda, who appreciates the sentiment but also warns that the estrangement may be permanent.

"Captain's log, stardate 3842.4. The interplanetary conference will consider the petition of the Coridan planets to be admitted to the Federation. The Coridan system has been claimed by some of the races now aboard our ship as delegates, races who have strong personal reasons for keeping Coridan out of the Federation. The most pressing problem aboard the Enterprise is to make sure that open warfare does not break out among the delegates, before the conference begins."

Gav found murdered.

As the delegates meet at a reception and Kirk and McCoy discover hints of Spock's childhood from Amanda, the Tellarite ambassador, Gav confronts Sarek asking about his vote on Coridan's admission, to which he replies that it would be known at the conference. Kirk also learns the Enterprise is being tailed by a mysterious unidentified vessel, and someone within his own ship is in secret communication with it.

Amanda speaks with her husband against their son's estrangement, but Sarek resists. Later, Sarek is again confronted by Gav, and Sarek reveals that he would vote in favor of admission, citing that Coridan needs the Federation's protection against illegal dilithium mining, which alludes to illegal Tellarite mining operations on Coridan. A brief struggle between the two ambassadors ensues, broken up by Kirk. Gav's lifeless body is later found stuffed up a Jefferies tube.

Act Two

Kirk, Spock and McCoy investigate Gav's murder. McCoy explains his neck was broken in a very precise manner, leading Spock to conclude it can only be a Vulcan execution technique called tal-shaya. Kirk then deduces that Sarek is logically the prime suspect, but when he is confronted by Kirk, Spock, and McCoy, it is revealed that Sarek is becoming increasingly ill with a cardiac defect, and claims he could not have committed the murder.

It falls on McCoy to attempt to heal the ambassador with surgery, but the doctor has reservations, what with his own limited surgical experience on Vulcans and the requirement of large amounts of a rare Vulcan blood type. Spock elects to take the role of blood donor, risking his own life by taking a dangerous stimulant to induce blood cell production despite Amanda's objections.

However, Kirk is suddenly stabbed by Andorian delegate Thelev. He subdues Thelev and alerts Spock on the bridge, before passing out in the corridor.

Act Three

Thelev in the brig

"Captain's log, stardate 3843.4. First Officer Spock in temporary command. The captain has been critically wounded by one of the delegates to the Babel conference. The ship is on alert status. We are still being followed by the intruder vessel."

Thelev is placed into custody. Kirk has survived the assassination attempt, but now Spock refuses to participate in the procedure while his captain is lying in sickbay. In a bold move, despite objections from McCoy, Kirk assumes command before he is fully healed, and sends Spock to surgery.

As McCoy takes blood from Spock and begins to operate on Sarek, Thelev attempts to escape from his cell, but is stunned unconscious. As he falls his antenna breaks, revealing a transmitter to communicate with the intruder vessel. The unidentified ship begins to move towards the Enterprise, causing Kirk to raise shields and go to red alert. The intruder ship begins to open fire on the Enterprise. The smaller vessel makes unbelievably quick passes and phaser strikes against the larger starship, too fast for Enterprise to return fire effectively, missing with a phaser attack. Despite being faster than the Enterprise, their weapons only consist of standard phasers according to Chekov, indicating to Kirk they have little chance of success. As the Enterprise continues to fight a battle against the smaller and faster ship, shuddering with each successive hit and suffering power losses, McCoy fears he may lose both his patients if the ship continues to take a pounding.

Act Four

As Enterprise struggles against the unknown vessel, missing with a full spread of photon torpedoes, Thelev is brought to the bridge, where Kirk confronts him as to his true identity. Thelev is uncooperative, preferring to taunt Kirk and enjoy the view of his fellow ship succeeding over the larger Enterprise. As the power goes out in sickbay, Sarek goes into cardiac arrest. McCoy and Nurse Christine Chapel try to make do with portable resuscitation equipment in an attempt to restart his heart again.

Meanwhile Kirk, fed up with Thelev's taunts and the other ship's apparently superior tactical ability, does the unthinkable. He drops the shields, then systematically fakes losing all power to lure the other ship in. Enterprise appears dead in space. The enemy ship appears to hesitate, then slowly closes in for the kill. As soon as it is in range, Kirk delivers phaser fire that cripples the vessel, to the observing Thelev's disappointment. The mystery ship then self-destructs to avoid capture, and Thelev commits suicide on the bridge via slow poison.

Dr. McCoy happy at finally getting the last word.


In sickbay, Kirk discovers that Sarek's surgery was a success, and not only are he and Spock recovering well, but also talking again as father and son. They even tease Amanda together, Sarek explaining that despite her rampant emotions a marriage to Amanda seemed at the time the only logical thing to do. When Kirk orders McCoy to perform an autopsy on Thelev to determine his true identity, Spock surmises Thelev and the attackers in the enemy ship were Orions, who had much to gain from disrupting the Babel conference so they could continue to loot Coridan of its dilithium. Kirk then slumps, finally too exhausted and in too much pain to continue, but he continues to protest as he is led to another empty bed in the ward by McCoy and Nurse Chapel. McCoy, exercising his rightful medical authority over his patients, is eventually successful in telling Kirk and Spock to lie still and be quiet, finally and gleefully gains his first "last word".

Background Information

Story and Script

  • D.C. Fontana's writing of this episode was inspired by several references to Spock's parents that had been littered throughout the previous installments of the original Star Trek series. Fontana later admitted, "'Journey to Babel' grew out of previous writing [....] There were all these little things that were running around in my brain." [1] One of the past references, dialog said in "This Side of Paradise" (which Fontana had previously worked on as a writer), was especially influential to the story. Explained Fontana, "The idea really came out of the line toward the end of 'This Side of Paradise', where Spock says, 'My mother was a school teacher, my father was an ambassador.'" (Star Trek: The Magazine Volume 1, Issue 2, pp. 84-85)
  • D.C. Fontana presented Gene Roddenberry with the idea of featuring Spock's parents in an episode. She reflected, "I was kicking around stories and I finally went in to Gene [...] and said, 'I want to do something about Spock's mother and father [....] Let's explore that relationship.'" [2] "I said to Gene, 'We've talked about them, let's show them,'" Fontana continued. "He told me to do it, and I came up with 'Journey to Babel'." (Starlog issue #118, p. 18)
  • Another influence on the episode was an extreme interest in exploring Spock's parentage. "We needed to see the family background that Spock was raised in, what's going on with him truly personally," Fontana related. (Star Trek: The Magazine Volume 1, Issue 2, pp. 84-85) Furthermore, she was interested in not only who Spock's parents were but also how they had shaped his identity. [3]
  • After D.C. Fontana chose to feature Spock's family in the episode, she began to formulate some of their backstory. Said Fontana, "I made some notes about what was going on with them." (Star Trek: The Magazine Volume 1, Issue 2, p. 85) She elaborated, "I sat down and created two characters, emphasizing the triangular relationship – the rift between Sarek and Spock, with Amanda positioned in the middle." (Starlog issue #118, p. 18) It was Fontana who named Spock's mother "Amanda"; she chose that name because it means "worthy of being loved." (Star Trek: The Original Series 365, p. 217)
  • D.C. Fontana was interested in making the aforementioned rift multi-dimensional. She remembered, "One of the points I [...] wanted to make believable in 'Babel' was that both Spock and Sarek were right – as their own convictions applied to themselves – and wrong – as their convictions applied to each other." (Babel #5; Enterprise Incidents, number 11, p. 27) This interpersonal friction, despite being between a full-blooded Vulcan and his half-Vulcan son, enabled Fontana to somewhat humanize the story. She observed, "It was really about the generation gap which [...] can be either a wall or, you know, something warm and lovely. And in this case, it was a wall, as far as between the father and son." [4] Fontana also reckoned that the family dynamic of having the hybrid Spock biologically between the extremities of the two others was "bound to create a lot of character problems." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 57) Gene Roddenberry approved of taking the opportunity to center the episode on the conflict between Sarek and Spock. [5] The multi-faceted character dynamics within the family propelled Fontana to write the story and script. "This was the first mention [in 'Journey to Babel'] that [Spock] and his father had been estranged. Well, why?" she wondered. "What's with his mother, what feelings does she have in this particular triangle between husband and son? And what kind of a woman was she to marry a Vulcan, go to Vulcan, live like a Vulcan, raise a half-Vulcan son? What was that all about?'" (Star Trek: The Magazine Volume 1, Issue 2, pp. 84-85)
  • The storyline concerning intrigue between the various ambassadors on board the Enterprise was subsequently added to the plot. With an indirect reference to the narrative about Spock's parents, D.C. Fontana stated, "I wrapped it up in a mystery, and in an adventure." [6]
  • The multiple minor differences between this episode's first draft and its ultimate embodiment include a brief discussion between Amanda and Spock in which she tried to persuade him to talk to his father. (Star Trek Monthly issue 29, p. 28)
  • In the first draft script, we learned that Sarek and Amanda had been married for thirty-eight years, that Sarek had been an astrophysicist before embarking on a career in politics, and that his father (Spock's grandfather) was Shariel, a famous Vulcan ambassador. (The Star Trek Compendium, p. 89)
  • In an early draft, D.C. Fontana planned for a Vulcan city to be shown in the episode's teaser, when Spock meets up with his parents. She explained, "The cost of doing a 'matte,' or painting of the city, was prohibitive." (Babel #5; Enterprise Incidents, number 11, p. 26) Hence, the shot was removed. [7]
  • D.C. Fontana was not concerned, while writing this episode, about how costly producing the story's variety of aliens would be, since she was aware that – because the installment is set entirely aboard the Enterprise with no extra planetary or ship sets needed – the finances could be spent wholly on the costumes and makeup. (Cinefantastique, Vol. 27, No. 11/12, p. 46)
  • In the original script, Sarek and his company were beamed aboard the Enterprise, but after going over budget with the expensive Vulcan, Andorian and Tellarite make-ups as well as the outer space footage of the Orion ship, there was no money left for the transporter effect. The Vulcans' transportation to the ship by shuttlecraft was decided upon because it could be done completely via the use of stock footage from "The Galileo Seven". (The Star Trek Compendium, p. 89)
  • In D.C. Fontana's opinion, not much was altered between how she envisioned this episode and the way in which it turned out. "It was shot pretty much as I wrote it – only a couple of things were changed," related Fontana. "One scene was added in which Amanda talks to Kirk about Sarek's relationship with his son. It seemed to me that that would have been inappropriate, and that she would not have blurted out all this information to Kirk. I did not have anything to do with that scene, and I think Gene Roddenberry rewrote it." (Star Trek Monthly issue 26, p. 25)

Makeup and Costumes


  • The matte shot of Uhura appearing on the screen in engineering is one of the smallest mattes ever used in the series, until the view discs in "All Our Yesterdays".
  • For some unknown reason, during the fight between Thelev and Kirk, just after Kirk's failed wall-kick, the comical sound effect of a coconut conk can be heard. This may have been meant to indicate Thelev's head hitting the floor. In the remastered edition of this episode, this effect has been removed from the fight.
  • The noise of the coded message sent by Thelev is also used in "Miri".
  • The Orion ship was recycled as the missile in "Patterns of Force".



  • Leonard Nimoy regarded this episode's depiction of Spock's relationship with his parents as a very worthy allegory for the difficulty many teenagers encounter with their own parents. [8]
  • When Mark Lenard was cast as Sarek for this episode, he was forty-three, only seven years older than Leonard Nimoy. (Star Trek: The Original Series 365, p. 218)
  • When she was offered the part of Amanda, Jane Wyatt had never heard of Star Trek before, and thought about it as a comedy. She expected to have a week of laughing on the set, but upon arriving for her first day of working on the episode, she was very surprised by how seriously everyone was taking the show. [9] As a tribute to her long and distinguished career, Wyatt is called "Miss Jane Wyatt" in the episode's closing credits.
  • D.C. Fontana was uninvolved in the casting of Mark Lenard as Sarek and Jane Wyatt as Amanda but ultimately approved of the selections of those two guest stars. "[They] were brilliant together [....] The two of them together looked superb," Fontana enthused. "They were just wonderful and they carried it off so well, even the Vulcanisms that we had to put in." [10]
  • Leonard Nimoy once recalled that Mark Lenard and Jane Wyatt came to him for advice on Vulcan culture. Nimoy replied that he had come to believe Vulcans placed great importance on their hands and hand gestures, and suggested Lenard and Wyatt find a way to demonstrate that, when on screen. The actors then created the finger-touching gesture seen in the episode. ("To Boldly Go...": Season 2, TOS Season 2 DVD special features)
  • James Doohan (Scotty) and George Takei (Sulu) do not appear in this episode, although Scotty is mentioned.
  • Frank da Vinci plays one of Sarek's aides. Russ Peek, who plays the other aide, also appeared as mirror Spock's Vulcan bodyguard in "Mirror, Mirror".

Continuity and Trivia

  • This episode introduces the Andorians and the Tellarites. Later episodes established that, along with Humans and Vulcans, they are two of the four founding members of the United Federation of Planets.
  • The gathering of aliens in this episode is of notable continuity. D.C. Fontana stated about the installment, "It was the first show we had done with a number of different aliens all together in one place with some goal in mind." (Star Trek: The Magazine Volume 1, Issue 2, p. 85)
  • This episode is the first mention of a pet sehlat that Spock owned in his youth. This animal appears in D.C. Fontana's animated episode, "Yesteryear", which also establishes the creature's name as I-Chaya.
  • Shras' suggestion that Spock forget logic and consider motivations of passion when investigating Gav's murder and Kirk's stabbing foreshadow the Vulcan-Andorian conflicts seen a century earlier, throughout Star Trek: Enterprise.
  • The conclusion of this episode involves a rare breaking of the fourth wall. (Star Trek: The Original Series 365, p. 219) McCoy was looking slightly to the right of the screen and appeared to be speaking to Amanda and Nurse Chapel when he expresses delight at finally having the last word. However, a more direct breaking of the fourth wall occurred in The Changeling, as Uhura, attempting to read the word "blue" on her viewscreen, turns directly to the camera and the viewers as she mispronounces the word as "blu-ee."
  • Spock's decision to join Starfleet rather than attend the Vulcan Science Academy is seen in the film Star Trek, wherein he makes the choice after being told by the head of the VSA admissions board that his academic accomplishments were all the more impressive given the "disadvantage" of having a Human parent. While this occurs after Nero's incursion changes the timeline, screenwriter Roberto Orci stated that this took place in the prime timeline as well. (citation needededit)
  • Tellarites were seen in two Season 3 episodes, with greatly modified masks: "The Lights of Zetar" and "Whom Gods Destroy".
  • Manny Coto originally pushed to have the short, gold-skinned species from this episode attend the Coalition of Planets conference in "Terra Prime", but it proved too expensive. He named the species Ithenite, a name that is mentioned in "Azati Prime" by time traveler Daniels. (citation needededit)
  • Spock reports that he gets readings of "trititanium" in the Orion ship's hull. It is not clear if the entire hull is made of it or parts of it. Trititanium is the material that the Enterprise's hull is made of, as Gene Roddenberry says in his novelization of The Motion Picture. It is not clear whether it is the same material as "tritanium" which is reported to be "twenty times as hard as diamond" in TOS: "Obsession".


  • D.C. Fontana has repeatedly named this episode her favorite out of all the Star Trek episodes she wrote. ("To Boldly Go...": Season 2, TOS Season 2 DVD special features; Star Trek Magazine issue 128, p. 46; et al) She noted, "It went into the Vulcan relationships between families. I think that's a story that's universal and timeless – that communication between parents and children. And that to me was the big story. The rest of it was an adventure, it was a spy story, it was a mystery, it was an action story – but all in all it was really about the parents and the child.... There had still been a vast lack of communication between them and they needed to find each other as parent and child." ("To Boldly Go...": Season 2, TOS Season 2 DVD special features) Generally, Fontana enjoyed the writing of this episode. "'Journey to Babel' was a very happy experience," she noted. (Star Trek Monthly issue 26, p. 25) She also remarked, "Bringing in the whole murder and the whole political background was a lot of fun. That was the main story, but personally I was more involved, in terms of interest as a writer, with the personal story of Spock and Sarek and Amanda." Fontana also commented that, despite the fact that the family-centered storyline "takes up very little room," it turned out to be the memorable aspect of the episode. "That's the part of the story that everyone remembers," Fontana concluded. (Star Trek: The Magazine Volume 1, Issue 2, p. 85)
  • Leonard Nimoy enthused, "Mark had a real sense of the dignity and the authority that the character needed. Jane was very human – which is exactly what that character needed. They were terrific together." ("To Boldly Go...": Season 2, TOS Season 2 DVD special features)
  • Director Joseph Pevney was selective with his opinion of how successful this episode was, though he was especially impressed by makeup supervisor Fred Phillips' work on the outing. "That was a good show in certain ways," remarked Pevney. "I thought the greatest contributor to it was the makeup artist. He did a fabulous job of bringing alien humanoids on board." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 57)
  • While Spock (Leonard Nimoy) was often deluged with fan mail on a regular basis, this trend was outdone following the broadcast of "Journey to Babel". Indeed, the fan mail poured into the studio at an incredible rate, only this time addressed to Mark Lenard, who for two weeks, topped those coming in for Nimoy. (The World of Star Trek)
  • The reference book Star Trek 101 (p. 18), by Terry J. Erdmann and Paula M. Block, counts this episode as one of the "Ten Essential Episodes" from Star Trek: The Original Series.
  • In the unofficial reference book Trek Navigator: The Ultimate Guide to the Entire Trek Saga (p. 123), both Mark A. Altman and Edward Gross (the book's co-writers) individually rate this episode 4 out of 5 stars (defined as "Classic!").
  • The unauthorized reference book Beyond the Final Frontier (p. 32) comments on this outing, stating, "[An] episode that is rich with color and texture. The relationship between Spock and Sarek is done extremely well, with Amanda's concern and disappointment adding an absent emotional context that makes the father-son relationship seem more tragic."
  • In the souvenir magazine Star Trek 30 Years, (pp. 89 & 90) the magazine's makers included this installment as one of their all-time favorite episodes from the original Star Trek series and described it as "an enjoyable romp with a heartfelt ending." They went on to say, "Mark Lenard is appropriately stiff as Spock's Vulcan father, Sarek, and Jane Wyatt is endearing as his Earth-born mother, Amanda."
  • In the magazine Cinefantastique, writer Sue Uram rated this episode 4 out of 4 stars and commented, "'Journey to Babel' marks a high point in D.C. Fontana's remarkable association with Star Trek [....] Clearly, 'Journey to Babel' is important from the Federation historical perspective of attempting to form a United Nations sort of body [....] However, it is the inner conflict of Mr. Spock with his father and the remarkable insights we are given into his unhappy childhood which make this show unique [....] Jane Wyatt and Mark Lenard put in sterling performances as Spock's parents. It almost breaks my heart when Amanda, loving her husband and her son, must use the ultimate emotion to force Spock to face his duty – that of guilt." The same issue of Cinefantastique also included the installment among "Trek's Top Ten." (Cinefantastique, Vol. 27, No. 11/12, pp. 75, 76 & 103)
