Be Excellent To Each Other

Diana Rigg's character

the cup was sitting beside her before he drank from it

then why did the fool say to Sansa "we must get you out of here at once"?

I'd assumed it was because her life was barely worth anything at the moment and she was alive mostly because Joffrey enjoyed torturing her; with Joffrey gone and her husband about to be arrested for murdering the king her chances of a happy life weren't about to go up. Especially as Cersei's a vindictive bitch who'd have lashed out at anyone connected to Tyrion for revenge, which puts Sansa in no small amount of danger. The fool owes her his life so he interceded when he saw the way things were going. Everyone blatantly thought it was Tyrion who killed Joffrey so it's not like Sansa needed to be smuggled away because people thought she'd actually done it.

Infantiregipiecide!

The wine was poured from in front of Cersei, so Joffrey wasn't even necessarily the target. Though that might be reading too much into it. I have read the rest of Book Three, but didn't even remember Joffrey had died! It was a long time ago.

I like how they emphasised how basically everyone there wanted him dead, bar his close family. So it could be Oberyn, Dondas, Sansa, Lady Tyrell, etc.

So glad that wee blond prick finally got his comeuppance

haha fuck Joffrey I'm glad he got killed.

A good theory on who poisoned the little fuck

Very interesting!

Seems fine, but why would she go through that rigmarole, and not just have the poison in her hat/pocket? It's not like anyone is going to frisk her on the way in!

The fact that he called it The Strangler proves that he's not so clever.

Plausible deniability. It was Sansa's necklace, afterall.

Indeed. I'm pretty sure it was Olenna but that just requires the opportunity of the cup sitting in front of her when no one was looking, everything about the necklace is just over-engineering it all for no reason. Unless someone was going to go through all her clothes eating everything they found and waiting to see if they dropped dead or not there's really no reason for all that nonsense.

ETA: Though from doing some Googling it appears that is indeed what happened, though I still think it's all a bit needless when the poisoning wouldn't require all this theatre and cast of characters. If you're going to murder a king you're not going to involve more people than you absolutely have to and you're certainly not going to leave it to the chance of someone's choice of costume jewellery. But, eh.

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?
