Remus is so awesomely professory. OMG the rules. I am dead. This is so filthy wrong but so, so compelling as well, and I love that they are both acknowledging how wrong it is. Whee! Oh, you Lupins and your moral ambiguity. THAT'S CANON. :)
Also, Remus emerging at the beginning with his cardigan buttoned lopsided made me cackle in abnormal ways. ♥ !!!!
