killed Joffrey

I just meant I'd Googled the theory about the necklace and there's enough people convinced of that and presenting evidence that I'm convinced you were supposed to get the impression the theory presented. I haven't looked ahead to see whether the actual culprit is ever revealed or anything.

The question of "who physically poisoned him" is still unsolved, I think. Even in book land. "Who plotted it" is semi-solved, or possibly even stated in the books. I read loads of wacky fan theories about it at the time I read it's all jumbled up in my head about what is real and what is crack-pot fan theory.

as for who plotted it -- I remember reading it was Littlefinger giving the head-net thing to Dontos to give to Sansa. One of the beads in the head was actually some rareish poison, possibly the one Stannis's dude tried to use on whatsherface -- the red lady -- in one of the prologues. (Or another poison mentioned in the books with the same symptoms. possibly the one Cat's sister used on her husband. Whatever.) This isn't a very helpful spoiler, is it? Basically: Littlefinger arranged it with highgarden.

edit: I remember the queen of thrones goes up to Sansa and compliments her on the head-net thing and touches it? And the internet later informed me that it's at this point she removes the poison?

I can't even remember what happened in the shop and I only watched it monday! For starters: There's no direct references or POV on the white walkers. There's nothing "seen" in the books about a magical "Nights King" type person touching babies and turning them into white walkers. There's vague references etc, but there's nothing so outright explicit

Also Bran and co go to Craster's house to find all of the murderers etc.

Craster's house in general. Once the Watch kill Craster in the books, that's the last we hear of it.

Jamie gets his head shaved. I think.

He doesn't wear a silly leather coat, like a silly beige Dante (from DmC)
