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: In Prometheus, Elizabeth Shaw and Charlie Holloway are a couple, in Covenant, Jake Branson and Daniels are a couple, Billy Crudup and Karine Oram are a couple, Tennessee Faris and Maggie Faris are a couple, Ricks and Upworth are a couple, Hallett and Lope are a couple.  It is logical to have married couple boarding colony ships as their trip is a no return.   I am wondering in the Alien universe, having married couple to go onto the same trip is encouraged officially.
Example Output: Is it a coincidence that there are many couples boarding ships in Alien?

Example Input: In Titanic, the elderly Rose visits a ship searching for the Heart of the Ocean diamond, set in a necklace. Unbeknownst to them, she actually carries it with her.  In one of the final scenes, a bare footed Rose walks to the railing of the search ship, climbs up on it in similar fashion to when she and Jack were on the prow of the Titanic, and throws it into the ocean.  The accepted answer in Why did Lovett invite Rose aboard his search boat in Titanic? suggests Rose threw it overboard for 'closure', but I simply cannot understand how that was closure. After all, it is not as though Jack (when alive) had any real interest in it. Nor did Rose. It was of interest only to her fiance Cal (who took his own life in 1929, when the stock market crashed).  It could be said that the return of the 'Heart of the Ocean' to the ocean, was ..poetic in a sense, but how was it closure? If not closure, then why did she do it?  Update  Interestingly, the original script differs from the movie in that the people searching for the diamond are there to witness her throwing it overboard. She even has a few words with Lovett as he is holding the object of his desire in his hand.     You look for treasure in the wrong place, Mr. Lovett. Only life is precious, and making each day count.   Another snatch of the script that might be relevant:    The hardest part of being so poor, was being so rich. But every time I thought of selling it, I thought of Cal. And somehow I always got by without his help.
Example Output: Why did Rose throw the diamond necklace overboard?

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?
