Yeah, that scene made me feel dirty.  My wife kept saying, HBO won't do it...it's a baby...they won't do it... (with he hand covering half her face.  I said, "Yes, yes they will and you know it.  It's going to happen."   
As for Roose, he is one arrogant SOB to think Ramsey wouldn't do what he did.  Ramsey is a massive liability and Roose should never have thought he could control him forever.  I knew that was going to happen forever.   
Tyrion...dude...that scene with the Dragons was such greatness.  Danny, Tyrion, Jon...i'll be surprised if they aren't the 3 riders.  (Some back story from the books; Tyrion has been obsessed with dragons since he was a kid.  So this scene made me really happy.)   
I am stoked they brought Bran's story back.  I understand why most don't care for his story, but I dig it.  And I like how they made the "child of the forest" look a little darker, more sinister as that is more how I had imagined them being...not literal children.   
Tormund and the wildlings...YES!  I figured there is no way they were going to let what they did to Jon slide.  One thing I really like about the show is the chemistry between Jon and Tomund.  The mutual respect they have for each other is great.  If real life, I could follow Jon and Tormund.  Then what the giant did to that dude that shot him with the arrow...yeah, I LOLed.   
All in all, great episode, and we will probably watch it 2 more times before next weekend.
