House
tyrell
The dowager who has spent decades letting her son Mace believe himself the one actually running Highgarden, and who came to King's Landing determined that no granddaughter of hers would suffer a Baratheon boy-king twice.
A Redwyne's Sharp Tongue
Born to House Redwyne of the Arbor, Olenna was married off to the notably unremarkable Lord Luthor Tyrell of Highgarden; a jape survives, which the text is careful to present as exactly that, that she talked him clean off a cliff to his death rather than endure him further. Whatever the truth of Luthor's end, Olenna spent the decades since running Highgarden's real affairs from behind her son Mace's ornamental lordship, with a tongue sharp enough to have earned her the name Queen of Thorns from friend and foe alike.
Thorns at the Purple Wedding
She escorted Margaery to King's Landing determined that House Tyrell's next queen would not share Sansa Stark's marriage to Joffrey, and in a quiet conversation with Sansa in the godswood not long after, came near enough to admitting a hand in the strangler poison that killed Joffrey at his own wedding feast that most readers take the confession as settled — though the words on the page stop just short of stating it outright.

The arc of Olenna Tyrell
This carries the character’s road through the published novels. Read on only if you do not fear to know.
Her exact hand in Joffrey's death is never stated outright in the published text; the strongest evidence is a conversation the reader is left to interpret rather than a confirmed confession.
These partings name deaths, endings, and roads not yet ridden in the books. Unveil them only if both roads are known to you — or if you do not fear to know.
Legacy
Olenna's career is the chronicle's clearest proof that a house's real ruler doesn't always sit in the lord's chair, and that the sharpest blade at any wedding is sometimes a grandmother's tongue.
