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

Input: Consider Input: How did another Engineer ship with a chest-burst Engineer and lots of facehugger eggs end up on LV-426 (Alien) when     all Engineers are supposed to be dead before David created the first facehugger eggs himself?   Wasn't the idea of Xenomorphs shown to exist before Alien: Covenant (2017) by the murals in the Ampule Room on the ship on LV 223 in Prometheus which might explain who piled up the bodies of Engineers on LV 223?

Output: How to explain this in Alien and Prometheus considering Alien Covenant plot?


Input: Consider Input: What does the ending scene in the movie Basic Instinct actually mean? After the killer has been caught by the police, we see in the last scene a very suspenseful, cliffhanger sex scene. Can somebody explain the ending of that to me? Does it mean the real killer is not caught after all?

Output: What does the ending scene in the movie Basic Instinct actually mean?


Input: Consider Input: In Desperate Housewives season one Linette takes her son's ADHD medicine and becomes very energetic. It gives her the ability to stay awake for hours on end and still do a good job and still have a whole lot of nervous energy...  (According to the plot the medicine has the opposite effect on non-ADHD people to what it has on ADHD people.)  Is this at all realistic?


Output: Realism of the effect of ADHD medicine in Desperate Housewives
