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

Example Input: Criminal Minds S9 Ep2 - "The Inspired (Part II)"  When they make arrests at the end:    There seems to be some difficulty over whether they have Jesse or Wallace. They use his learned nervous tick as a differentiator and arrest him accordingly.   Why would they need to do this?     Surely they could just ask him questions that Jesse would know the answer to (e.g. who are these pictures of? What happens in a normal day at work?) and demonstrate it was Wallace by his lack of knowledge of Jesse's life? Also, the BAU would knew he suffered from hallucinations, if they kept him talking long enough he would eventually give himself away.   Perhaps there is there some aspect of the American legal system that I am not familiar with? Or did miss something in the episode?
Example Output: Why the confusion over who was arrested in Criminal Minds?

Example Input: Earlier in Jumanji: Welcome to the Jungle we see the dialogue:    Alex. What's up with all these candles?    Uh Citronella, one of my weaknesses is mosquitoes.   If Seaplane has a weakness to mosquitoes and is stung by one, why doesn't he immediately explode like other characters exposed to their weaknesses?
Example Output: Why didn't Seaplane explode when stung by a mosquito?

Example Input: Snape had already told Voldemort about the prophecy, or at least half of it, so what is the point of seeking that prophecy once again? It doesn't seem to have anything that would have been helpful for him to defeat Harry.
Example Output:
Why did Voldemort want the prophecy in Order of the Phoenix?
