Owosekun was raised in a Luddite collective on Earth. Her family held no religious beliefs. (DIS: "New Eden") She felt that she scared her parents when she decided to choose her own path, but hoped that they would forgive her one day. (DIS: "Such Sweet Sorrow")
The Federation-Klingon War
Because of her experience living in a community without technology, Owosekun was recommended by Michael Burnham to accompany her and Captain Christopher Pike as part of the landing party sent to the New Eden town on Terralysium, a primitive human settlement. When the team were attacked by Jacob, she was able to free them from captivity by using a magnet to release a slide bolt on a trap door. (DIS: "New Eden")
When Burnham decided to take the Discovery forward in time to the 32nd century to elude Control, with no chance to return, Owosekun was among the officers who volunteered to accompany her, leaving behind her former life. (DIS: "Such Sweet Sorrow")
Afterwards, Owosekun, along with the rest of the volunteering Discovery crew, was presumed dead by Starfleet, based on the testimonies of the USS Enterprise senior officers. (DIS: "Such Sweet Sorrow, Part 2")
