Question: CONTEXT: For the same reason that Jeff doesn't immediately call the police with his suspicions: fear that if Thorwald realizes he has been made by an outside observer, he will dispose of all the evidence and escape without prosecution... Lisa is buying more time by being taken under arrest, and the event was intended to appease Thorwald to some extent. He was already making mistakes (retaining his wife's wedding ring due to sentimentality), and Lisa was clinging onto the thought that their plan was not yet foiled. The arrest itself was actually a means of getting Lisa safely out of the apartment, and of getting the wedding ring (as evidence) into the hands of the police.  <sep>  Q: Why didn't Lisa tell the truth about Thorwald to the police? A: For the same reason that Jeff doesn't immediately call the police with his suspicions  Q: Why does she get herself arrested? A: Lisa is buying more time by being taken under arrest 

Answer: Did Thornwald run away?


Question: CONTEXT: Tyrion did give the necklace to Ros, but we never actually see him do it. We know about it from another scene. When Ros and Theon Greyjoy are together she's wearing the necklace and tells him that it was a gift from Tyrion. As for why, Tyrion is usually very generous to the whores he beds, and he is extremely wealthy. A necklace of that sort wouldn't have meant much to him.  <sep>  Q: Why did Tyrion give the Lannister pendant to Ros? A: Tyrion is usually very generous to the whores he beds, and he is extremely wealthy 

Answer: Do you know when he gave Ros the pendant?


Question: CONTEXT: I just did a bit of digging on your behalf regarding this line, and there seems to be no concrete definition of it from any official source. That said, I found several interpretations along the way, including: 1) "You cannot wash away your sins."; 2) The blood is worn as a badge of merit on the blade; 3) The blood remains on the blade and not on your hands (meaning you are relatively guilt-free). Personally, considering the overtly religious themes within the film, I would side with option 1, especially since Priest Vallon is saying the line.  <sep>  Q: What's the meaning behind the phrase "The blood stays on the blade"? A: there seems to be no concrete definition of it from any official source  Q: In Gangs of New York, a character is told not to wipe blood off a razor when he cuts himself cause the blood stays on the blade. What could that mean? A: The blood remains on the blade and not on your hands (meaning you are relatively guilt-free  Q: What about another meaning? A: You cannot wash away your sins  Q: Are there any others? A: The blood is worn as a badge of merit on the blade 

Answer:
Wait, in what way would there be merit?
