Do you think she means it like how there's more than two Queens?

[She's been thinking about this a lot, too. The Queens still haven't left her mind, even in times of relative peace.]

This whole place is set up like chess. Red and White. And then you have Hearts kicking around, putting a fist through everything. Maybe that implies a third realm. Something hidden.

[Shepard stops, thinks for a second, and wonders if it's relevant.]

Were you here for that one New Years? Where we were in the other world, with the White Queen?
