I wound up leaving with Kenny. I saw an image someone made of Clem and Kenny walking away, with a ghost of Lee in the middle, and that's pretty much how it felt for me. I had told myself on a second playthrough that I'd let Kenny walk away, but in the end I couldn't do it.
I always wonder about the characters we never hear about again, like Christa. Do we assume she died? What about the people at Howe's? They aren't there in the Jane endings afaik. Or Nate and the guy with the beanie from 400 Days?
Anyway, I think Alex's train of thought is mostly in line with my own on this season. Good and fairly solid, but with inconsistencies and it had the tough task of living up to Season 1. I'm glad they didn't kill Clementine at the end, though.
