killing the kid in passing just as Harry had killed Sirius

Draco's breath hitched and his eyes brightened suddenly, and Lupin thought with satisfaction that he had hit where it mattered.

Ooh. There are some great lines in this. A lot of them, actually. Excellent writing! We do need more Draco/Lupin fics, or more Draco/anybody-who-is-not-Harry fics for that matter, and this ficlet reminded me why. I like the ruthlessness in your Remus, the fact that the calm professor exterior is just a face, and your Draco was dead on. Short and perfect (if not sweet) - I loved it :)
