I think it's only a matter of time before Merle and Daryl see each other again, but i think it will be against the Gov orders.
I'm thinking that the Gov won't allow Andrea to leave, but i can see them hooking up in the near future as they seem to get getting on quite well.
I've decided that if Rick or Daryl are killed off then im going to boycott the show as they are the best two characters.
