This story is a sequel to Mistress (Adagio's Big Comeback)

An alliance forged.
The sirens restored.
New friendships made.
An exile welcomed home.
But when you invite as daunting a figure as Adagio Dazzle back to Equestria, no matter how much she seems to have changed, there's always going to be loose ends, so on the same night as Adagio and her human boyfriend return home to the other world, Twilight seeks to question Sunset Shimmer for her side of the story.
What ensues is a look through some of the events seen in Mistress, but through alternative views, as well as more context on the actions and thoughts of those involved by means of new scenes, as well as a chance for some heart to heart talks between two distant friends.
