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")
