The plot twist? Somewhere in the past, Jasper was kinda cool with the infected. then he got his crew at set sail for island douche
Jasper just got this crew so it seems he always been a douche. He might turn it up a bit know he is the captain of the douche squad (hey, new name for those guys) but it seem being a dick is how he copes with everything much like Sammy being ...well... Sammy.
did... did jasper just insult and defend charlie in the same post?
Think that part of (rl) Jenny sneaking in Jasper's deeper character.
