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

Ex Input:
Maria and Nicholas existed in Trevor's daily delusion because of his guilt about the past hit and run.   But how come Ivan exists in his imagination?   Are there any clues in movie that can prove Ivan's actuality in Trevor's past? Or is Ivan's figure totally delusional as in schizophrenic people?

Ex Output:
How come Ivan exists in the Machinist?


Ex Input:
In the Maze Runner, WCKD wants the kids to escape the maze, but they have made it almost impossible to do so because they have Bio-Tech creatures called Grievers created by WCKD patrolling the maze at night, but when kids go into the maze but they don't come back alive if the doors closed, that's saying something, but wouldn't they send something else instead of Grievers in? I understand they want to map the the patterns of the killzone in the kids brains and their immunity to the flare, but to kill them while in the maze? surely WCKD would want them to live and save humanity rather than be murdered by a gigantic maze.  What I'm trying to say is: They could have picked a creature that wounds the kids but not kills them so why didn't the organisation do this instead?

Ex Output:
Why would WCKD use Grievers?


Ex Input:
I am referring to the scene at the end of the movie where William exposed her and admitted to her that he knows. She is running to Williams house for the car and then she is leaving.  Why did Adaline run and drive away from William and Ellis? She already was exposed and it isn't clear from what or whom she ran away.

Ex Output:

Why did Adaline run away?
