Boimler giving a Captain's log

In 2380, during a stop at Douglas Station, Boimler was wounded when fellow Ensign Beckett Mariner who was giving him a hard time for writing his own mock captain's log. Mariner, who was intoxicated on Romulan whiskey, then sliced his leg with a bat'leth. Later, while assisting in second contact efforts with the Galardonians, Captain Freeman asked Ensign Boimler to monitor Ensign Mariner's activities.

Brad Boimler introduces Barbara Brinson to Beckett Mariner

Boimler briefly dated Lieutenant Barbara Brinson of the USS Vancouver Before 2380, it had been quite some time since Boimler had "taken a lover."

Memorable quotes

"I need you to tell me that your senior officers are infallible heroes!"
"Well they're not, and that's okay. We all joined Starfleet to dive first into the unknown. We're explorers, of course we don't always know what's going on. Did Picard know about the Borg? Did Kirk know about that giant Spock on Phylos? Did Dr. Crusher know about that ghost in the lamp thing from the Scottish planet that she hooked up with that one time? That whole thing. You clearly want us to say that the captain and her crew messed up, but we simply don't have the full story, and that's the truth! Whatever they did, I guarantee you it was all for good. You have shown no evidence that they're guilty of a crime, in fact, I find you guilty of trying to take them down with this sham of a trial! DRUMHEAD!"

"If this was actually happening, they'd send the Enterprise. But, you know. Artistic license."

Background information

In developing the characters for Star Trek: Lower Decks, Mike McMahan described all four leads in an 10 August 2020 interview as a combination of other Star Trek characters, parts of himself, and people in his life. Boimler was partially based on Sam Lavelle from TNG: "Lower Decks", "a great Starfleet officer, but he's just so dedicated to trying to rank up and he's so careful about everything that he doesn't get to be Kirk."
