Calibration (джен)

Remus's mind is usually a tidy place. The worst has already happened, what's left to be scared of? His fears are labelled, annotated, and most of all, archived. For one evening, though, he'll have to let them come out and play. (Remus prepares the Boggart for his lesson with the third years. Featuring Severus Snape as an unwanted critic, and Sirius Black as the elephant in the room.)
