Between the two bros, Brett is the most dangerous, and I think Scottie knows it after the whole "mist" thing. Winston's a douche, but not much of a threat. Strategically, best to go after Brett, but I'd rather see Winston go.
Rockstar is by far my least favorite HG. Kaitlyn is pretty much useless, but her crazy makes me laugh.
If it wasn't for his high pitch voice that annoys the hell out of me, I might cheer for Scottie, but he needs to hurry up and finish puberty. One of those ladies should go ahead and make him a man.
