I could see 2 scenarios where Chop is scum.
1) KY is really neutral. Chop cops him as neutral to gain townie points with KY.
2) KY is scum and on a team with Chop.
I'm still wary of the fact that we have 3 people kinda on the ropes between Orange, Cat 5, and KY. And none of them seem to think Chop is the least bit suspicious but they all seem to think each other is very suspicious.
