He just told him that Margery will also have an walk of atonement just like cersie. Tommen later tells about it to cersie, after which cersie tells it to olenna and kevan in the small council meeting.
The only person she thought to save was her son, Tommen, but did Tommen have any idea that Cersei was planning to burn everything to the ground before he killed himself? Prior to being forced to stay in the Red Keep by the Mountain, Tommen probably had no idea what Cersei had planned.
By convincing King Tommen to ban trial by combat, he ensures that Cersei will lose. If she loses, it proves that she committed incest and thus Tommen has no rightful claim to the throne.
Game of Thrones never explicitly revealed who Tommen's rightful heir to the Iron Throne was after his death, with Cersei seizing the crown instead. Cersei became Queen of Westeros after Tommen's death in Game of Thrones season 6, but whether or not she was actually his heir to the Iron Throne is another matter.
They made Tommen a bit older on the series, but actor Dean-Charles Chapman was still 16 years old when he filmed the scene...
Cersei almost uses the poison on Tommen, to prevent him from being captured when the battle seems lost.
Tommen is Queen Cersei Lannister's youngest son and, like his siblings, he is also the son of Cersei's brother Jaime Lannister, but he is unaware of this, as he believes Robert Baratheon to be his father. Tommen is described as handsome and sweet-natured but weak-willed.
Princess Myrcella Baratheon is known to the Seven Kingdoms as the middle child of King Robert Baratheon and Queen Cersei Lannister. A member of House Baratheon of King's Landing, her siblings are Princes Joffrey and Tommen.
Jaime was the older brother of Tyrion and the twin brother of Cersei. Their mother died giving birth to Tyrion. Due to his place in the Kingsguard, Jaime could not inherit his father's lands or titles, making Tyrion his father's heir; a fact which vexes Tywin.
In Fire and Blood by George R.R. Martin, Rhaenyra does indeed take the Iron Throne and become queen over the Seven Kingdoms, however, her reign is short-lived. Given how much House of the Dragon has been diverging from the source material, nothing is really certain about what will make it into the final cut.
In the books, though, Tommen is only 8. That doesn't stop his family from marrying him off to Margaery, but there is, thankfully, no consummation.
Tommen Baratheon (Callum Wharry)
However, the young actor was recast with Dean-Charles Chapman (who briefly played Tommen's cousin Martyn Lannister in season three) when the role required an older actor for Tommen's more prominent and mature storylines.
Tommen Baratheon
Charles-Chapman previously played the part of Martyn Lannister, Tommen's cousin.
If you study the family dynamics of the dysfunctional Lannisters it is not surprising that his mother Cersei disregarded her son's death. She, while loving Tommen, viewed him as a pawn in her game. She sought to manipulate him to control Westeros, as she did with Joffrey.
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.
High sparrow did not tell tommen any of that. He just told him that Margery will also have an walk of atonement just like cersie. Tommen later tells about it to cersie, after which cersie tells it to olenna and kevan in the small council meeting.
After his death, Robert's bastards are ordered to be killed by his heir Joffrey Baratheon, Robert's supposed legal heir and the new king; Gendry, subsequently flees the capital.
Jaimes hair has grown significantly darker between season 7 and 8 due to his walking away from his house (Cerci) and joining the north. It's a representation of how much of a golden lion they are or in this case are not.
Stoneheart accuses Brienne of serving the Lannisters, and forces her to choose between killing Jaime or being hanged. When Brienne refuses to choose, Stoneheart orders her and her group hanged.
A Feast for Crows
In the ensuing confrontation, one of Arianne's co-conspirators, Ser Gerold "Darkstar" Dayne, attempts to kill Myrcella; although unsuccessful, he cuts off one of her ears and leaves her scarred.
Myrcella Baratheon was poisoned by Ellaria Sand through a kiss on the lips as she departed for King's Landing with Jaime and Trystane Martell. Though both individuals were poisoned, Tyene Sand was able to produce an antidote for Ellaria as symptoms appeared, while Myrcella died in Jaime's arms.
Technically, she's had four, but in Season 1, she told Catelyn Stark how her first, a “black-haired beauty” she had with Robert, died of fever shortly after his birth. If Maggy's prophecy is correct, we can expect tragedy in Cersei's fifth pregnancy as well.
He asks if Ros can hit Daisy and she spanks her gently. Joffrey asks if Tyrion sent them and Ros says that Tyrion chose them himself. Joffrey forces Ros to hit Daisy with his belt, hard enough to make her scream. He hands Ros a stag's head sceptre, and she protests that too much pain will spoil the pleasure.
In a recent interview with Vulture, Dean-Charles Chapman — who played Tommen on the HBO drama — spoke about what drove his character to jump out the window of the Red Keep, explaining that it was ultimately his mother's actions.
He has an older brother, Joffrey, and an older sister Myrcella with the same obfuscated parentage. Tommen is good-natured and passive in contrast to his brother Joffrey, who sometimes bullied Tommen for amusement. Like his sister, he is fond of his uncle Tyrion Lannister.
