Why didn't TNG go to the mirror universe?

Yeah, in the prime 'verse Kestra DID drown. She wasn't eaten by a wolf.

Yes, I know that. I'm confused about this wolf thing.

^There is an appearance by a 'wolf' in "Dark Page", though I think that's just a manifestation of Lwaxana's mind trying to scare Deanna away. I can somewhat see how there would be some confusion.
