I expected Christa and Omid to betray you at some point.
I expected Clem and Lee to die together.
I expected someone in the group to kill someone else in the group.
I expected the kidnapper to be some kind of genius that would fuck with your mind when you entered the hotel. (and to the sequence to be longer)
I expected the kidnapper to make you make a choice between your life or Clementine's life at some point...
... and there's alot more. I guess I expected many different things.
