Why the break? Presumably because this weekend is Memorial Day weekend, which is always a hard weekend for TV, what with everyone being distracted by picnics, vacations, and general merriment. Indeed, last year the epic "Blackwater" episode aired over Memorial Day weekend, leading to a dip in the ratings, despite the fact that it was one of the most anticipated episodes of the series thus far.
What can you expect from "The Rains of Castamere" when it does air? Here's the official synopsis:
Edmure (Tobias Menzies) meets his bride. Jon (Kit Harington) faces his harshest test yet. Bran (Isaac Hempstead Wright) discovers a new gift. Daario (Ed Skrein) and Jorah (Iain Glen) debate how to take Yunkai. House Frey joins with House Tully.
