Yes, what QS said.
The whole - "we have to go and get a White Walker to prove to Cersei (and probably Dany) that they're real" - storyline is annoying. Just fly a bloody dragon over the wall and have a look.
And it really looks like they're going to drag out the "secret" of Jon's parentage as long as possible. I suppose Bran can't send a raven to Jon with that info as it's too confidential, but still, Jon should be aware of this by now.
I liked seeing Gilly back too, and her revelation to Sam was nicely thrown in.
