Entertained

Watching Harry, Ron and Hermione interact was only mildly entertaining but seeing as it was the best Sirius could hope for so long as he was trapped in his family's decrepit home, he availed himself of it as unobtrusively as he could. Tightly wound and more than a little obsessive made Hermione a fascinating specimen for him to analyze. Once and only once the prim bookworm had asked him what he would do first once his name was cleared. Sensing an opportunity to rattle her cage he let his mouth slowly curve up in a languid smile before answering.

"Sin."
