I agree Jon's resurrection was somewhat lame.
I still think (if the popular theory is true and he's half Targaryn) that it'd have been neat to have him not burn in a burial fire and resurrect as the fire burned. But, oh well...it is what it is.
Targaryens do burn, as the very very very old maester who was at the Wall did.
Dany coming unscathed out of Drogo's pyre was a miracle, George R.R. Martin explicitly said so using that very word, "miracle". It was a once in a lifetime event, Dany herself would burn again if lit aflame.
About the episode... yay, he's back! we waited a long time for him but finally he's back... welcome back, Hodor!
Am I the only one, and I can't believe I'm typing this, who's sad at Roose Bolton's dead? Robb's killer, this cold blooded calculating soft spoken bastard reduced to a pawn in Ramsay's scheme? I know that Game of Thrones isn't exactly the kind of story when good guys are avenged with a satisfying vengeance and a witty one liner to top it up, but it's so unsatisfying that Roose Bolton dies the same way as someone else in the next scene - betrayed by his own kin. Joffrey's death was satisfying, even if it was not a direct revenge, this one feels so random. I bet in the books he wouldn't have died that way.
I guess Ramsay will be made the centerpiece of the storyline, he will go down in the battle against Jon Snow and so Roose wasn't "needed" anymore... but what an unsatisfying demise fot that interesting bastard.
And I want a comedy spinoff of Tyrion and Varys, hehe! loved his scene with the dragon, and yeah, the Bran stuff was golden.
