Pike's Deja-Vu

Anonymous asked: Watching back through everything from the beginning again, and I picked up on something I'd never really paid attention to before. In episode 1 at 55:05 pike (mercer) says "I feel like I've been here before." Have we ever learned what that meant, or is that another loose end waiting to be tied?

That was in reference to the vision Pike had of the Underdark, the same vision where she also ‘visited’ the sea of bone and glass that Vox Machina crossed in Episode 8.
