Even Olenna has to laugh. After chugging the alcoholic solution, she reveals to Jaime what we, the audience, had assumed for a few seasons: she was the one who drugged his drink, turning him into a breathless, blood-gushing, blueberry of a boy and ending his reign of tyranny. Surprise!
If you've been paying attention, this wasn't so much a revelation as one final, fulfilling jab from a grandmaster of Westerosian conspiracies. Then again, there's a lot to pay attention to in the world of Game of Thrones, so we wouldn't blame you for missing these vital signs that Olenna was the one who did Joffrey in. It all starts in the premiere of Season 4, when the embarrassed, surviving-by-the-skin-of-his-teeth knight Dontos Hollard gifts Sansa a necklace. Why?
