This week's episode introduces several new characters: Gendry, Samwell Tarly and Gregor Clegane. We see some well-executed scenes from the book, and we see several new scenes, invented to convey key pieces of backstory and character development. Things wrap up with a thrilling cliffhanger when Catelyn and Tyrion meet at the Inn. We don't get to see the Innkeeper chewing her disgusting sourleaf, but perhaps that is for the best.
