Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

[EX Q]: In Person of Interest, in "The Day The World Went Away", Finch's cover identity is exposed after he visited a cafe he brought Grace to. How did Samaritan establish the link between Professor Whistler and Harold Finch? As far as I know, Samaritan knows:   A person who looks like Finch used to come to the cafe A person who looks like Finch used to order the same thing   That, to me, is not enough to conclusively prove that Professor Whistler is indeed Harold Finch. What other information could Samaritan possibly possess to help it expose Finch's cover identity? Was it the fact that Finch was talking to The Machine?
[EX A]: How did Finch's cover identity get blown?

[EX Q]: What was the reason behind the conversion of human into USB in the movie Lucy?   Why did the heroine change herself into USB when she used 100% of her mind, and then texted the policeman ("I am everywhere")?   She traverses many old eras, and in the end just forms a strange structure, giving the researcher (scientist) USB and then that huge structure falls off?
[EX A]: Why did Lucy convert herself into a USB?

[EX Q]: A recent trend that I've noticed (or I'm just crazy and need to delete this question) is to release a major film outside of the U.S. first, even if it's a Hollywood film. Usually a week or so later the film gets released in the U.S.  Why are movies being released this way?
[EX A]:
What's with the trend of releasing movies outside the US first?
