You know, I've thought about the Arya thing and I'm guessing she must play a massive part before the end of the series. I'm thinking that her plotline could've just been condensed and then we don't see her for a season. I'm under the impression that the writers didn't want to do that, or she becomes a badass later and is The Hand of the King or something. I've said this multiple times, but I'm waiting until the conclusion of the series to judge a story arc. It's still possible that there was a reason that her arc was so drawn out. In short, I'm not a big fan of it right now.
Next week though......any predictions? I think that Ramsey will lose but NOT die. He will retreat like a coward and we will get to see scared/terrified Ramsey suffer. I'm also banking on the supporting armies coming and helping Jon, LOTR style where they show up out of nowhere.
Unfortunately, it does seem like that's likely, with Littlefinger riding over the hill at the end. F that guy. I hope Sansa chops off his nuts at some point.
