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]: As shown in the movie Persephone was the wife of The Merovingian, who himself was an obsolete program who denied being deleted. My question is, does anybody know anything about the origins of Persephone? There seems to be no specific information that indicates who she previously was.
[EX A]: What were the origins of Persephone in The Matrix: Reloaded?

[EX Q]: In the movie Baby Driver, in the Coffee Run scene, some of the lyrics of the song are plastered in graffiti on the walls while the main character walks to the coffee shop.     Has this ever done before or was Edgar Wright the one who created it?
[EX A]: Has this "lyrics with song" style of scene ever been done?

[EX Q]: In the television series Supernatural, at what point of time and during which season did Sam lose his powers?  EDIT: I mean to ask whether it was around the time Sam was brought back from hell without his soul by Cass, that he completely lost all his powers?
[EX A]:
When does Sam lose his psychic powers?
