I'd rather someone break into Gubal Library than stage Garlean castrum break-in #938465. I'm only partially joking, but my main point is that there are worse ways to write a character discovering their discipline(s).
That being said, I wouldn't overthink it. In the worst-case scenario, if someone really gets THAT curious IC about where your character learned red magic from... you don't have to oblige them. You can keep it vague or tell them it doesn't matter. If red magic was taboo, this would be a different conversation. But now that we've established it's not, nobody should care overly much either IC or OOC.
