Q: Saw this 1959 Hitchcock's masterpiece Rear Window last night. One of the great classics! Enjoyed it!  I just didn't get one thing. Why didn't Lisa (Grace Kelly) tell the complete plot and truth about Thorwald when the police arrived at his home? Why did she get herself arrested and made the things more tense? Thorwald could have ran away from that place (but thank god it didn't happen)! :-/

A: Why didn't Lisa tell the truth about Thorwald to the police?

Q: Some TV shows the order of the episodes on the DVD and the order how the episodes where aired is different, e.g., Freaks and Geeks. The fact that on thetvdb there is a field "DVD order" implies more examples.  What is the reason behind that difference? I don't see any sence in it, in particular if the episodes depend on others and the order is important.

A: What is the reason that the air order and the DVD order of a tv show is different?

Q: In Let the Right One In (orig.: Låt den rätte komma in), after Oskar found out about Eli's true nature and let her into his apartment he asks her:   Oskar: Who are you?    Eli: I'm like you.    Oskar: What do you mean?    Eli: "What are you staring at? Well? Are you looking at me? So scream! Squeal!", those were the first I heard you say.    Oskar: I don't kill people.    Eli: But you'd like to, if you could...to get revenge. Right?    Oskar: Yes.    Eli: I do it because I have to. Be me, for a little while. Please... be me, for a little while.   But I don't understand what she means with her last words. What does she want to say with "Be me, for a little while"?

A:
What does Eli mean with the words "Be me, for a little while"?
