Bad Charlie Lol.

To be more constructive. Charlie knows what hes talking about. The Oceanic 6 are keeping a secret. They need to go back and rescue everyone else. Hence "They Need You"

He only wore a hood when he was swimming. That was to hide his face. So you couldn't really tell who it was at first. Then you know it must be him having vision of Charlie. At first I thought Jack was coming to break him out of prison!
