Sam Tarly is one of my favorite characters, show and books. You're starting to get a glimpse of his true awesomeness now, north of the wall, but he gets so much cooler. And of course Tyrion is right up there too. If I were a knight in Westeros, knowing what I do about all the characters, I'd swear fealty to Tyrion. Because he's actually a decent guy, which is rare in this universe. Plus, dude needs someone sworn to him. And of course the Stark kids are pretty cool, and I'm rooting for them, but tbh I'm disappointed in Sansa. She's kinda stupid sometimes.
