It didn't make much sense to me as it was happening. I thought it was a little overkill, no pun intended, for a simple broken oath. But when they said, "The Lannisters send their regards," it all made sense. I haven't read the books, so I really don't know, but I wouldn't be surprised to see Jon Snow take over the Stark family. You know, the bastard son being the underdog and all. Maybe I'm way off. Anyway, great episode. Can't wait until the finale.
