For those complaining: The book doesn't involve any actual stripping, and the character is more of the sad, meth-head truck stop variety stripper. You're not actually missing out on much.

Honestly, Mrs. Day is a much better role for her than Crissy Cates. Much more interesting character.

Krissy Cates's brother isn't in jail in that book. She's an only child. It's Libby Day's (Theron) brother.

Honestly, the season 4 finale seems pretty obvious. The Battle of Castle Black is your grand set piece in the penultimate (although so much shit happens at Castle Black that that whole thing should play out over basically the entire season), and the season ends with Littlefinger's reveal.
