Teacher: Given a paragraph about movies, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.
Teacher: Now, understand the problem? If you are still confused, see the following example:
CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep>  Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished.
Solution: Why has it been diminished?
Reason: The question is valid since it is on the same topic and a follow-up of the previous answer in the conversation. The question asks about the reason why the power held over Margaery by Cersei have diminished.

Now, solve this instance: CONTEXT: Since becoming the Three Eyed Raven, Bran has the ability to remember, well, everything that's ever happened in Westeros, including how he fell from the tower (although given that Sam was able to tell him some, ahem, surprising news, it seems that he doesn't just "know" everything in the past). Bran also has a habit of repeating things he never could have heard people say, just as a subtle way of saying "just so you know, I know". As he throws Bran from the window, Jaime quips to Cersei, "The things I do for love". When Bran paraphrases this line back to Jaime while staring him in the eye in S8e2, it becomes clear to Jaime that Bran knows what happened. He does something similar with Littlefinger, quoting "chaos is a ladder" at him, despite it being impossible for him to have heard the original conversation.  <sep>  Q: When does Bran Stark remember Jaime pushing him? A: Since becoming the Three Eyed Raven, Bran has the ability to remember  Q: What does he remember exactly? A: everything that's ever happened in Westeros, including how he fell from the tower (although given that Sam was able to tell him some, ahem, surprising news  Q: How can he remember everything that has ever happened? A: Bran also has a habit of repeating things he never could have heard people say 
Student:
So how does Jamie discover that Brian remembers all things?
