The dead guys, how did they die?

Titus Oates - He was very bad, even in the beginning. In the end, he survived the night that he thought would kill him, so he went outside and never returned. His last thoughts were of his mother.
Wilson -Walked to his death with Scott
Bowers -Walked to his death with Scott
Evans - He died when they were out of food, which was good, because he was unable to move on and they didn't want to leave him behind.
