I'll post my longer review later.
But here some thoughts of this episode I watched yesterday.

Joffrey!! My little boy!!
I'm just so sad he's dead! He was so bitch perfect all these seasons that I will miss him so much!
Now I'm sad to think we'll not see Jack again. But the King is dead! Hurrah for the King!

Stannis! I can't believe what they did with him!

Ramsey is such a little bastard! His duo with Theon is awesome and they show really well the relationship they have in the books.
But yeah as you I don't like her girlfriend, it's totally useless to add this character.
I mean she's clearly here only for some sex scenes we'll see later.
