I think Lee will die no matter what happen, I just hope TT don't let the group members die like flies... I cannot handle when they let Christa die who is pregnant. I just hope the last survivors will be Christa, Kenny, Clem & Molly.
When someone is infected he can barely talk anymore right ? So talking on the walkie-talkie will be much harder so he have to reach fast to the group. I see at the end the boat still working but who makes it there is the other thing. For some reason I hope Lilly shows up and kills (or let me say, help

lol) Vernon and the others to free Clem or atleast help the last survivors to reach the boat. TT could give Lilly a good farewell and show that Lilly is a good person.
For some reason since Molly said: "She is like me" at the end, I could see her rescue Clementine. Ben will be at the next episode for 1 time pretty badass and sacrifice himself, the same goes for Omid that cause a very emotional scene w/ Christa.
