Part 2. 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. <sep> FOLLOWUP_Q: Why has it been diminished?
Answer: King Joffrey is dead, and his younger brother Tommen is now king.
Explanation: The answer why Cersei's power over Margaery has now diminished is clearly mentioned in the passage.
Part 3. Exercise
CONTEXT: A properly executed plot twist often causes opposite reactions of what you've just described. People want to watch the movie again because the ending was so unexpected that they need to review the whole thing to get all the puzzle pieces together. "Fight Club" is a great example, in my opinion. There's a lot of dialogue (especially the lines from Helena Bonham Carter) that doesn't make any sense if you don't know the ending. You will enjoy and understand Fight Club much better after a second view. There are many ingredients that define the quality and longevity of a movie. Directors should not be afraid to use a plot twist, but relying only on this trick - especially if it is predictable - may ruin the whole experience.  <sep>  Q: Is there any evidence of "Big Twist" movies having poor post-cinema sales? A: Directors should not be afraid to use a plot twist, but relying only on this trick - especially if it is predictable - may ruin the whole experience  Q: Do you think this is a common reaction though? A: A properly executed plot twist often causes opposite reactions of what you've just described  <sep> FOLLOWUP_Q: So, for up ad coming directors, is this the type of movie to stay away from
Answer:
Directors should not be afraid to use a plot twist, but relying only on this trick - especially if it is predictable - may ruin the whole experience
