Thank you! And I still didn't entirely get everything explained that I wanted to. But I think those are mostly things that readers can figure out on their own, or which can be safely mentioned later (for example, that the Masked Lady's use of the AB initials, like Angelica Banks, was pointing back to Andromeda).

I feel sorry for Andromeda, but her particular brand of soured grief is even more dangerous than Voldemort's madness, because she's more cautious and has planned further ahead.
