A full-blown Teen Survivor would surely feature at least 1 or 2 showmances, frequent outbursts among the cast (pretty girls vs. the jealous drama queen, jocks vs. less popular insecure guys), and quite possibly more lying / manipulation / deceit than has ever been shown in Survivor. Remember that 18 or 19 year olds aren't fully grown up and probably don't understand the consequences of being an asshole or acting out on national TV. Plus, they won't have real-life careers and reputations to return home to where a "lie" on Survivor could haunt them long-term.

I imagine a F4 would feature a male class clown, a mute smart bitch, a drama queen villainess who backstabbed a lot of people, and an introverted "good ol' boy". Jocks would be immediately eliminated around the merge, and a major usurping would probably happen at F8 or F7 where a power couple or power "popular" clique got dethroned. It would probably be great TV if actual fans of the show were cast.
