I think he means that if you watch the 2nd week's episode now, you'd have to wait two weeks to see another new episode as next Sunday's episode you would have already seen...which I am totally doing. I can never follow the characters' names so well since I haven't read any of the books, but I find the show to be very well done and I am a big fan of a lot of sci-fi/fantasy novels. I know the general plot, but I know I'm missing out on a few non-verbals that are going on.
