Jaime has easily become the best character in the book. After all, from the start of the series, he was just some amoral asshole who fucks his sister and attacks people for little reason at all. Now, he's an amoral asshole who gets things done without bloodshed and is actually looking out for the little guys.
Much love for Tyrion and that barefooted Septon as well.
I see a new and unhappy theocracy being imposed by the Faith in one or two books time. Cersei really REALLY screwed up.
It's a pity nothing happened on a 'Red Wedding' scale though. Also, Brienne is probably not dead. After all, a good third of the book is about her, and it would be rather silly for her to simply be killed off with no real implications.
I do not see the Night's Watch surviving the next two books.
