Strange's expression shifts to a frown as soon as the idea of this mystery fae being Ignatius's mother is floated.

"Not everyone has positive relations with their parents," says a person who is very obviously speaking from experience. "Besides, even before all of...Polaris happened to Ignatius, there was all that business with him being kidnapped. I doubt any reunion will be as smooth as you two wish."

And that's even before taking into account the fact that his aspect was changed! Though hell, there's a whole lot of assumptions going around here and Strange wants clarifications, so he just bluntly asks that mystery fae,

"Are you one of his progenitors or are these guesses off base?"
