In reality, it was Olenna who had poisoned the wine. She had arranged with Littlefinger to end Joffrey's life and used Sansa Stark in the process. Littlefinger had worked with Dontos Hollard to deliver the poison, which was hidden in a stone attached to a necklace given to Tyrion's wife by Olenna.
Olenna reflects on the horrible way that Joffrey died, and the gruesome details that the poison caused; she admits that part was unintentional on her part, as she had never seen the strangler work in person before. Jaime is shocked to learn Olenna was the one who poisoned his son.
Out of her love for her granddaughter, Olenna poisoned Joffrey and let Tyrion take the blame. Only Margaery knew the truth, after Olenna confessed she couldn't bear to see her granddaughter married to Joffrey any longer.
However, some are wondering why did Jaime kill Lady Olenna on Game of Thrones? The simple answer is: because Cersei wanted him to. Despite many fans' hopes, Jaime is still very much in love with Cersei, which was proven after they hooked up again for the first time in a long while during Sunday's episode.
During the wedding, Lady Olenna Redwyne secretly takes one of the crystals from the hair net and uses it to poison the wine in King Joffrey's goblet. Joffrey appears to choke on a piece of his wedding pie, and dies, unable to breathe. The wine, originally red, has turned purple.
Joffrey's evil behaviours took root in (1) he was impotent; and (2) he was sexually aroused by inflicting pains of others. Isn't it curious that not once in the books or in the TV series Joffrey ever had sex? He was of age. Tommen was 5 years younger than him and had no problem consummating the marriage with Margaery.
During the feast, the Tyrell matriarch sneakily took the poisoned stone from Sansa's necklace and put it in Joffrey's wine glass while he was mocking his uncle, cutting open his wedding cake with a sword, and just acting the pompous fool in general. The Kingchild drank the toxic alcohol and died - painfully.
Of course, the audience already knew. In season four, episode four, Olenna reveals to Margaery that she was the one who poisoned Joffrey, explaining that there was no way she'd let her 'marry that beast.
So, the killer was … Olenna, obviously! Although she was helped by the fickle Petyr Baelish, who organised the poison for her. Once the admission of guilt was made, fans flocked back to season four to see if they could pick up on Olenna committing the crime.
After she guzzles the poisoned wine, Olenna confesses to Jaime that she was the one behind Joffrey's murder and tells him to pass that news along to Cersei.
They wrote: "The widely accepted theory is that Sansa's necklace had a poisoned crystal, which Olenna Tyrell sneakily took off while she was talking to Sansa in the scene before Joffrey dies.
In the TV show, Margaery doesn't know that the wine is poisoned, which doesn't make sense since she could have drunk from the cup at any time. Now being man and wife, Joffrey could have offered her the first sip, which she would most probably accept.
Just moments before Margaery Tyrell was killed in the wildfire explosion orchestrated by Cersei Lannister in the finale of the last Game of Thrones' season, she realized that something wasn't right. However, Natalie Dormer—who played the fan-favorite queen—had long expected her character's fate.
Littlefinger killed Joffrey as revenge for the Red Wedding.
Joffrey Baratheon/Lannister: "Hurry up, this pie is dry. Mmm good, needs washing down.
On Game of Thrones, the rose is the sigil of House Tyrell, and when Margaery gave her grandmother, Lady Olenna, a note with a simple drawing of a rose, she was confirming her loyalty to her house and her family above all else, so they wouldn't be fooled by her sudden piety.
Olenna Tyrell, née Redwyne, is the widow of Lord Luthor Tyrell and the mother of Mace Tyrell, Lord of Highgarden. Born into House Redwyne of the Arbor, she is commonly known as the Queen of Thorns because of her sharp tongue. In the television adaptation Game of Thrones she is portrayed by Dame Diana Rigg.
This note, and the surreptitious manner in which she delivered it, was Margaery's subtle way of telling her grandmother that despite all appearances, her loyalty remained with her house. It was a reassurance.
And while Olenna is already dead, meaning no more revenge can be exacted against her, Cersei knowing that Olenna killed Joffrey could maybe — just maybe — change her perspective on Tyrion and Sansa.
She then tells her the lords of Westeros are all sheep and Daenerys is a dragon, so she should be a dragon. In "The Queen's Justice", Jaime Lannister seizes control of Highgarden on Cersei's orders. He confronts Olenna, granting her a painless death by poison, putting it in her cup of wine as she watches.
Who was the Targaryen that they tried to marry Olenna Tyrell (The Queen of Thorns) to? Prince Daeron Targaryen , the youngest son and fourth child of King Aegon V and his Queen Betha Blackwood. They were betrothed when they were nine.
But Joffrey's death scene is gruesome and ignoble. He dies painfully, awfully, convulsing, blood streaming from his nose, his eyes bugged, his skin translucent.
The strangler, the poison used to kill Joffrey, is smuggled to the wedding in the deep purple amethysts in Sansa Stark's silver hair net, and the wine the king drinks is described first as dark red and soon after as purple. Joffrey's face turns red and then darker as he chokes from the poison.
Fortunately, the answer is... nope! Sansa is not pregnant with Ramsay's baby, at least according to a reliable Game of Thrones spoiler and news website Watchers On The Wall.
