Although I was looking forward to Selmy returning and that scene ended up being great, especially the creepy kid. So was Tyrion vs Tywin, which foreshadowed so much of what the ending of Season 4 will probably deal with.
The episode showed how increasingly hard it is to do justice to all characters. Even with Arya and Jaime absent the others hardly got enough screen time. I hope the show will keep juggling that well.
You mustn't be afraid to dream a little bigger, darling.
