I wonder, has there been any thought put in to how they will handle the children's aging during the filming between seasons? I remember on the Lost TV series that they had to write out the role of Walt because he was aging faster than the character in the show was supposed to be. Obviously they can't write out some of the primary child characters in these books. What happens in 3-4 seasons when Bran or Arya are that much older, but their characters were only to have aged a year or two at most. Kids grow and change really fast in that pre-teen to teen age range.
