Member of the USS Discovery
At the time of the arrival of Captain Christopher Pike, Commander Nhan, and Lieutenant Evan Connolly from the USS Enterprise, Linus was sick, sneezing on Connolly in a turbolift ride to the bridge. (DIS: "Brother")
He was later present on the bridge when Ensign Sylvia Tilly was taking her spot in the Command Training Program, only to be distracted by an entity only visible to her. Along with the rest of the bridge crew, Linus looked puzzled as to why it appeared she was talking to no one. (DIS: "Point of Light")
While present at a briefing on the Red Angel, Linus apologized that Discovery's universal translator was still having difficulty translating Saurian into Federation Standard. He proceeded to explain that there was no known analogs to the images of the Red Angel.
When Discovery was pulled out of warp by a large, mysterious sphere, Linus assisted Commander Michael Burnham with analyzing the sphere. He reported that the sphere was approximately 100,000 years old. (DIS: "An Obol for Charon")
Linus was eating bamboo while sharing a meal and discussion with fellow Discovery crewmembers Joann Owosekun, Keyla Detmer, Nilsson, and Paul Stamets. Jett Reno joined them and challenged them to an autoantonym game, reminding Linus he was "0-for-3" so far and asking him if he was ready for "another round". Linus replied he was "hatched ready". During this exchange, Reno called Linus by the nickname "Bamboo Boy". (DIS: "Through the Valley of Shadows")
Linus was one of the crewmembers who volunteered to stay on Discovery and accompany Commander Michael Burnham into the 32nd century. Based on the testimonies of the USS Enterprise senior officers following the battle near Xahea, Starfleet had presumed him as dead. (DIS: "Such Sweet Sorrow", "Such Sweet Sorrow, Part 2")
After arriving in 3189, Linus assisted in repairs of the EPS relay system. He informed Commander Nhan that the grid on Deck Six had been repaired and she directed him to report to Deck Eight for additional repairs. Philippa Georgiou asked about Linus's visual spectrum, which he stated was 74,000 nanometers. Georgiou then volunteered to accompany him to Deck Eight, though it was a ruse so she could leave the ship to find Saru and Sylvia Tilly. (DIS: "Far From Home")
Linus had more trouble than most crew members learning to use the personal transporters provided by the Federation once Discovery tracked down its headquarters. Attempting to beam to the mess hall, he found himself instead in the captain's chair on the bridge. Later he unintentionally beamed into a turbolift occupied by Burnham and Cleveland Booker, having meant to go to the science lab. (DIS: "Scavengers")
Linus was played by regular guest actor David Benjamin Tomlinson.
