GOT S4E7 "Mockingbird" may be my favorite episode thus far with the twists and turns. (major spoilers)
Arya and the Hound relationship is awesome and gets awesomer. She kills for mercy, and Sandor becomes human.
Tyrion and Jamie's discussions, then Tyrion and Bronn saying he won't fight for him, and then Oberyn saying he'll be Tryion's champion! Very good stuff there.
Then of course, Baelish. Kissing Sansa (No!) then you knew one of them one dying at the moon door. (What?!?)
Such an overall very good episode.
