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.
Although the High Sparrow seems a harmless old man, he has a will of steel. Though his devotion to the Seven is genuine, he is also a deeply ambitious man, seeking to obtain political power in order to enforce what he sees as the will of the Gods on the populace, whether they want to or not.
In the fourth episode of Game of Thrones' sixth season, King Tommen tells Cersei to beware of the High Sparrow. "There's something I want to tell you, something the High Sparrow told me... I promised him I wouldn't tell anyone. If he found out..."
How did the High Sparrow get so much power? The High Sparrow's rapid ascent to power is a result of the disillusionment of the lower classes throughout all the tumultuous changes of power and the lingering threat of war. Religion is a powerful tool to accumulate followers from among those who have nowhere else to turn.
Yes, the High Sparrow was confident that Cersei would show up for her trial. He believed Tommen had the authority to order Cersei to attend, even if she didn't want to. He thought Tommen really wielded the power of the King.
Although he didn't know what his mother was up to, he had to have known it wasn't good. Then, as he stood by the window, he watched as King's Landing exploded in green fire, and his love, Margaery, died in the flames. It was only then that Tommen fully understood what his mother had done.
The High Sparrow had Cersei arrested because of her relationship with Lancel Lannister, the man who enters the room at the end of the scene.
Then she is arrested by the High Sparrow, because Lancel (yes, the same one who used to sleep with Cersei), radicalized by religion, confessed their affair and snitched about Cersei's relationship with Jaime.
While he is still quite misogynistic in the books, the Sparrow is in some ways less villainous. Unlike the usual corrupt Septons and nobility, the High Sparrow seems to genuinely want to help the poor, even selling much of the Faith's wealth to buy food for the poor.
They made Tommen a bit older on the series, but actor Dean-Charles Chapman was still 16 years old when he filmed the scene...
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.
"The reason it all goes t--s up is because Margaery wasn't in control of the battle against Cersei," Dormer told EW. "She had to hand the reins over to the High Sparrow and Cersei outplays him. By the end, Margaery is a victim of the High Sparrow's incompetence.
In order to evade her trial and get revenge on her recent enemies, Queen Cersei Lannister had the Great Sept of Baelor destroyed by wildfire, killing everyone inside and around the building.
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.
Ans. a. Sparrow did not tell the other birds because she would not have to share the grain with them.
The High Sparrow
The High Sparrow (Jonathan Pryce) was famously evil to the most evil characters in the Seven Kingdoms. But any leader, religious or otherwise, who supports torture and public humiliation is at least a little bit evil himself.
When Cersei has an affair with Lancel Lannister, their cousin. Cersei sleeps with their cousin Lancel throughout seasons one and two. Lancel does everything she asks him to, including causing the death of King Robert. In season five, Lancel confesses the affair and the death of Robert to the High Sparrow.
Jaime knows that Cersei has been sleeping with him, that her children are his and that she caused Robert's death. That doesn't automatically make the charge about Lancel true, but he knows those charges are at least completely justified and not trumped up in the slightest. Cersei admitted that she slept with Lancel.
Baelor then placed his sisters—Daena, Rhaena, and Elaena—in their "Court of Beauty" in the Red Keep, later called the Maidenvault. Baelor wanted to preserve the innocence of his sisters from the wickedness of the world, and from the lusts of men, and prevent them from tempting the men at court with carnal thoughts.
Cersei has been involved in an incestuous affair with her twin brother, Jaime, since childhood. All three of Cersei's children are Jaime's, which is unbeknownst to Robert. The rumored illegitimacy of her children causes a power struggle in the wake of the king's death, known as the War of Five Kings.
The prolific author recently revealed that his famous militant religious group, the Sparrows, is actually based on a famous religious organization's past. The cruel but oft effectual Sparrows, with the High Sparrow at the head, are actually based on the medieval Catholic Church.
Cersei almost uses the poison on Tommen, to prevent him from being captured when the battle seems lost.
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.
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.
