What ever I don't care if I just burned my supplies ill just swim my way out of this stupid island
Cole left the island and started swimming as far as he could go until he got so tired and could no longer swim. This all went down after he burned all of his survival supplies that Garvey gave him.
HA that's what you get for being a snitch
