Orton Merryweather

Lord Orton Merryweather is a recurring character in the fifth and sixth seasons, though he first appears in the fourth season, debuting in "The Lion and the Rose".

Season 4
Orton plays a small part in Season 4. He arrives in King's Landing alongside Mace Tyrell to celebrate Margaery Tyrell's wedding to King Joffrey Baratheon. To go along with his sigil, the gift he offers to the newlyweds is a massive horn of plenty. Afterwards, he is shown to be disgusted by Joffrey's play about the War of the Five Kings.

Orton later enters the court trial of Tyrion Lannister for his alleged role in the murder of King Joffrey, and later attends his trial by combat, where he witnesses the death of Oberyn Martell.

Season 5
Orton is one of the many lords present at the wake of Tywin Lannister.

Orton's role increases when he is asked by Queen Regent Cersei Lannister to become the new Hand of the King following Tywin's death. Orton happily agrees, though in reality Cersei only offered him the role due to his lack of intelligence and pliability. Orton would then witness Cersei's burning of the Tower of the Hand.

At the next Small Council session, Orton explains how severe the Iron Throne's debts are, specifically to the Iron Bank of Braavos. Orton and Olenna explain that the Tyrells are offering to pay off some of the debt, but Cersei refuses to become in debt to House Tyrell.

Orton next appears in bed next to Cersei, with the Queen Regent apparently having seduced him. Orton fails to realize that Cersei is just using him.

Due to his pliability and Cersei's seduction, Orton agrees to go with her plan to frame Margaery Tyrell for murder. Orton approaches the High Sparrow and falsely confesses to the High Septon that he had slept with Margaery on several occasions, and that she told him he wasn't the only one. The plan appears to work as the Faith Militant arrests Margaery; but the High Septon, suspicious of Orton's story and appearing so pleased to confess, has Orton imprisoned as well and tortures him to gain the truth. Under torture, Orton reveals the truth, leading to his permanent arrest as well as Cersei's.

Season 6
Orton remains imprisoned for the majority of Season 6. The High Sparrow shows his depressed state to King Tommen, explaining that what happens to Orton is what happens to all sinners if they can't reach salvation.

Orton eventually agrees to give up his titles and join the Faith Militant to escape imprisonment. He appears at the trials of Margaery and Cersei as Brother Orton, with a seven pointed star carved into his head. He is killed when the Sept is blown up by Cersei.
