Carly/Doug dead is just why this game lack of story branches (actually: 1, the story is always the same no matter your choices).
See too that after kill Carly/Doug and there is another important choice like leave Lilly or save her, in the end she always leave and when you save her you canīt say nothing to her and she donīt do nothing, so itīs the same.
No story branch here means no money by telltale to make a huge game, which is not necessary that they donīt have money but that they want to earn more money and they are just doing the easiest things...
Seriously, this game until now looks like what an indie group of people might do...
I really hope that the success of this season bring us a much more high quality game in the next episodes or seasons.
