Godsdamn, what an episode.
I was already a fan of Baelor going into this episode and I was further struck by his honor when he gave Duncan wise counsel when he didn't have to. But I was still blown away when he decided to fight alongside Duncan against his own family. Regardless of how the Trial of the Seven ends, he will remain a favorite character of the season (along with Lyonel, of course) and it's truly refreshing to see a decent and kind Targaryen, especially one in power (as opposed to Aemon and Egg).
