The third of the nicknamed prisoners who travel with Michael Burnham in 2256 and attack her in the mess hall of the USS Discovery, only to be overpowered by the former first officer.
Stone is a convict who appears in the Discovery episode Context Is for Kings. He shares a prison shuttle with Michael Burnham, Cold and Psycho, and the group's conversation makes clear how notorious Burnham has become in the six months since the Battle of the Binary Stars.
After the damaged shuttle is brought aboard the USS Discovery, the prisoners are escorted to the mess hall under the eye of security chief Ellen Landry. There Stone and the others start a fight with Burnham, who puts all three down in a few moments with Suus Mahna.
Landry stops the brawl, and when the shuttle is repaired the other convicts are sent on their way while Burnham is kept aboard at the wish of Captain Gabriel Lorca.
