Given a paragraph about movies and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.

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  Q: So how does Jamie discover that Brian remembers all things? A: it becomes clear to Jaime that Bran knows what happened  <sep> FOLLOWUP_Q: Can you tell me anything else about Bran?
Yes

CONTEXT: The biggest reason is that they weren't prepared for an attack. The Lannister army wasn't supposed to be there, but rather defending King's Landing and Casterly Rock. Lady Tyrell even goes on to say that fighting was never really the Tyrell's strong suit, so in-universe it wasn't a surprise that they fell so quickly. Also, wealth doesn't equate to army size. Just because the Tyrell's have a lot of money doesn't mean that they have a huge army. In fact, house Lannister is in significant debt because of it's huge army and all of the fighting they've had to do over the last few years.  <sep>  Q: How was a powerful house so easily defeated?
Yes

CONTEXT: Well, in answer to the first part: Yes, the water in which John Loomis (Chiwetel Ejiofor) was swimming/bathing when Ann Burden (Margot Robbie) came up to him is irradiated. Without getting too "spoilery", the area in which Ann lives seems to be one of very few (if not the only) radiation-free zones at the time of the story. However, the water in which John was swimming comes from outside of that area (the waterfall). As for the beneficial effects of the bath, I think the link to the "Silkwood Shower" reference by @Will-Feldman is probably as good an explanation as any. Try to get as much of the irradiated water off of the body as possible. John is obviously still going to be affected by his exposure, but there's no reason to allow more of the radiation to seep in if it can be prevented.  <sep>  Q: Why does Margot Robbie wash Chiwetel Ejiofor in Z for Zachariah?

Yes
