The Walking Dead - Walking Dead Season 1
This is a realistic comparison, without being biased... I'm going to make a comparison of who would make a better story arc, Kenny or Lilly in season 2.
If Kenny were to be In season 2, he would be a completely different man. Much more mentally scarred. One idea I had was that Kenny would have experienced head trauma while trying to escape from the alley or abandoned building. That way, he wouldn't remember anything from season 1. He'd have a general sadness inside, but not know why. He found a group of bandits and joined them. Clementine meets him in season 2 with her group (I thought you were dead) and perhaps he is now an antagonist. He meets Clem but has no clue who she is and Clementine is heartbroken.
Eventually he and his group become antagonists and cause terror to the group, causing them to leave the cabin. Maybe Kenny turns out to even be Carver. Near the end of the season, Clementine shows Kenny a picture of either Lee or Kenny's family drawing (depending on which the player put in the fire in ep. 1) and he begins to remember everything.
From here, the story continues.
As for Lilly, maybe she joined the bandits after being left on the road or stealing the RV, and Clementine reminds her of her dark past that she's been trying to leave behind, and wants her and her group dead so that shadows of her former self will be gone forever.
I dunno, what do you guys think?
