Basing on the previous episodes, I think that it will be like this:
Christa's baby dies, turns into a zombie in her belly and kills her, like in the Alien movie. Omid is killed by zombie-Christa, because he cannot bring himself to shot her and his leg injury prevents him from running. Ben screws something up again and this time dies in the process. After some small disagreement with Lee, Kenny calls him a selfish asshole and runs away on his boat, leaving rest of the group behind. Lee kills the radio man, finds Clementine and they manage to fight they way through a huge horde of zombies and find another survivor camp. They learn that Clementine's parents live here. Just when they are to meet them, Clementine accidentally trips, falls from the stairs and breaks her neck. Lee dies from the bite and is shot in the head. The end.
