Given a paragraph about movies, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. 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:'.

Q: CONTEXT: It's in Parry's mind. At the start of the scene, people in Grand Central Station are just walking, making noise, chaotic. Parry is looking for Lydia, whom he is in love with. When Parry sees Lydia, classical music starts, and the chaotic crowd is now in sync (in Parry's mind). They begin waltzing around him. Parry has a smile on his face. He follows Lydia through the sweetly dancing couples, all the way across Grand Central Station, and the universe is in harmony, for him. When he finally loses sight of Lydia on the other side, the couples go back to being a crowd, and the music stops and is replaced with the dissonant noises of the throng. Here is the scene: EDIT I also found an interview with director Terry Gilliam (below) regarding that particular scene. In the video, at 2:10, he says, "I just love the idea of Perry being so in love that, you know, the world changes to whatever dreams he has." <sep> Q: Why people were dancing at the subway? A: When Parry sees Lydia, classical music starts, and the chaotic crowd is now in sync (in Parry's mind). They begin waltzing around him <sep> FOLLOWUP_Q: What makes the crowd so chaotic?

A: At the start of the scene, people in Grand Central Station are just walking, making noise, chaotic

Q: CONTEXT: Travellers is about saving people in the future not in the present by altering the course of history. The people from the future can only do this safely and without unpredictable side-effects on the timeline if they don't "save" lives in the past. Their future technology actually does allow them to replace people who were not about to die, but they regard this as a moral problem and it is forbidden. But they can take over those lives if they were about to be eliminated from the timeline, hence the apparent paradox of "saving" McClaren. But they haven't actually saved McClaren at all, they have replaced him with a traveller. Early in the series only people about to die get replaced. Obviously the whole point is to alter the timeline but the travellers are aiming not for minor alterations like saving a single, random life, but for big alterations that radically change the course of history. One of their protocols actually forbids them from saving other lives as well even when they know someone is about to die (but not be replaced). This [minor spoiler alert] becomes a source of some dramatic tension in later episodes. <sep> Q: Why does MacLaren die in the first episode of Travelers? A: Travellers is about saving people in the future not in the present by altering the course of history Q: what does this mean, How can people do this? A: people from the future can only do this safely and without unpredictable side-effects on the timeline if they don't "save" lives in the past Q: Does this then mean that Mclaren is not dead? A: they haven't actually saved McClaren at all, they have replaced him with a traveller Q: Have they saved lots of people from dying? A: One of their protocols actually forbids them from saving other lives as well even when they know someone is about to die (but not be replaced <sep> FOLLOWUP_Q: They saved him from falling down an elevator shaft, is this typical in other episodes?

A: Obviously the whole point is to alter the timeline but the travellers are aiming not for minor alterations like saving a single, random life

Q: CONTEXT: I don't have a source but I am fairly certain, Daenerys didn't know about Jon visiting Tyrion in the cell because of the later scene with her and Jon and her reaction to Jon asking mercy for Tyrion. Then the question comes, why did Unsullied let Jon through. We saw in S08E05 that Tyrion managed to see Jaime after convincing the guarding Unsullied that he has a higher authority then the person they possibly got their orders from. They have seen Jon by her side when she's standing on King's Landing steps and proclaiming her victory and further conquest. So they know he is a close ally to her. They must have gotten their orders from Grey Worm or some other officers to guard the prisoner but when they see Jon, a close ally of Dany and a Commander of the Northern forces, they let him through because they know he has a higher authority and possibly Queen's confidence in the visit <sep> Q: Did the queen allow Jon to visit Tyrion? A: don't have a source but I am fairly certain <sep> FOLLOWUP_Q: Why would she allow Jon to visit though?

A:
Daenerys didn't know about Jon visiting Tyrion in the cell because of the later scene with her and Jon and her reaction to Jon asking mercy for Tyrion
