It'll answer anything, so long as you preface your query with, "Mirror, mirror, on the wall..."
Note, however, that the mirror does not show you scenes; rather, a smokey, masked faced appears. It's compelled to answer your questions, and truthfully, but it does so only auditorily.

Hmmm “how to make the guy I’m crushing on fall in love with me” that’s what I’d ask. I like “Snow White” because my mom always said that I look like Snow White, but now I act like the Evil Queen, but I still look like the princess and I like apples. I’m an Evil Queen looking for her prince.
