I don't want Kenny to die. I've said it once, I'll keep saying it. The Telltale Walking Dead world may be just a bit TOO brutal. Eventually, a character is going to live as long as Clementine does, maybe longer. It's borderline hard to believe that every single person from each of Clem's groups would die. Just my opinion. I think Kenny could be that character that survives and survives and survives. His boisterousness is the only thing that gives me pause.
On the Christa thing... the more I think about it, the more I think we're going to get a reunion by the end of Amid the Ruins. That sneak peek was so bland aside from the glimpse of Rebecca going into labor, which we all knew would happen. A Christa shocker seems to fit.
