I don't understand how that's going to work. Isaac Hempstead-Wright (plays Bran) is 15. When we see him again, he's going to have changed so much. Unless the storyline involves the Bran character aging overnight, that's going to annoy me. Perhaps it's a silly gripe, but that's just something that irritates me: obvious changes in the actor when the character shouldn't be changing. It's going to very difficult for the showrunners to pull off a convincing chronology going forward. Not just for Bran's storyline either. Still looking forward to season 5 though.
