I've been thinking a lot about this lately. Kenny is one of my favourite characters, but...
I think he should die in episode 4. He always take a lot of screen time and player's attention, that's just his character. While I do like it about him, he already got 7 episodes to have a larger role in. In "in harm's way" we were introduce to new charactersm like Mike. But what do we really know about him? Almost nothing. Why? One of the main reasons is Kenny. He just gets much more time in the episode and steals time for other characters to develop. Now, most of the people don't care about Mike and think he's not important and will die soon.
Kenny returning in season 2 was nice, I hoped for it to happen. But at the same time, I hoped that he won't take on such a big role again. But he is doing that. I would say he can just disappear and never return, but we would get another 999999 theories that he is coming back. I was really sick of those after some time. Before "A house divided" came out, everything related to this game was filled with people getting crazy over Kenny.
So yeah, I think his return was a nice fan service, but I don't want Telltale to take it too far.
