I read this earlier today, allowing it to cook, and I still haven't arrived at the reaction that captures my reaction. At this point, the best I can give you is a resounding echo of all the comments above. Is it enough if I say it matched exactly what I was gunning for when I threw Greyback in your writerly lap? Jo's evil monsters were conceptually chilling but written merely lukewarm wicked, cool compared to the nano amount of unscrupulous Greyback you just gave. And Remus here so clearly shows that his virtue is his willingness to imitate the villain, that he's strong enough to bear that.

From the perspective of craft, I love that you haunted me with dialogue, not description. Being out of Remus' head and witnessing his interaction with Greyback was where I hoped this would go.

THANK YOU! :D *hugs*
