...was Ben's decision to feed the bandits. (Note, this shouldn't spoil episode four by itself but I can't control the other posters in this thread)
Everything else is a direct consequence of that poor decision, and we didn't even get to make it.
Sad enough, I agreed with Lilly's father about adding new mouths to feed in Episode 2, but didn't get the option to toss Ben out. 'Tis sad, really.
That said, it's still a great game, it just sucks that the biggest decision in the entire season wasn't really ours to make.
