A few theories about Kenny's role in S2
1) He'll appear in a cliffhanger, possibly at the end of ep. 6, 7 or 8.
2) He'll be living within Tavia's community, perhaps in the midst of a relationship with Bonnie.
3) OR, as the leader of another survivor group.
4) Kenny may or may not be emotionally unstable following his experiences in S1. His status as "hero" or "villain" in S2 could depend on his relationship with Lee in S1.
5) Kenny tries to become another surrogate father for Clementine...and it doesn't last very long.
