I have an idea for a question, however, I am reasonably certain no-one is going to be able to give a solid, definitive answer to it because I am reasonably certain it hasn't been explained in film and isn't something that the director is likely to have explained out of film.
Should I still ask it?
Note: I do not like giving my potential questions away on Meta because I have a paranoid fear that someone out there will not be as caring and loving as I am of Movies.SE and will question snipe me and post it themselves (YES, I'm looking at you!) but take this question, which is much lamer and less interesting than my real potential question, as an example:
"In Despicable Me, where did Gru get the 'dog' Kyle?"
Ok, not a great example as this may be a question others would ask the director or they would address themselves in commentary, but suspend disbelief and imagine they wouldn't.
