Sybil Trelawney and Quirinus Quirrell: the Seer fallen to teaching and her bright young thing. Of course they never meant to fall in love. But they did, and so here is that story.
This is BrokenPromise of Ravenclaw, writing for the Great Hall Cotillion 2013.
Thanks to Sophie (the owl), who looked over some of this for me.
Story Notes: For the purposes of this story, Quirrell was Sorted in 1979.
