Not a bad episode, and some things are explained. The necklace Dontos gave Sansa was fake, and had hallowed glass instead of jewels. Grandma Tyrell wants to wed Margaery to Tommen(or her third king for those keeping count), and Tywin is already trying to get his claws deep into Tommen even before he is crowned king.
It was hard to live up to the last episode, but they did a great job of pushing the story along without giving any solid evidence. I can only suspect that Baelish & Varys had something to do with it.
