Guest was currently in the restricted corridor past the hours everyone should've been away in their common rooms. Two things that should never be done at the same time. You were beside a table and chair, both of which were cleaned of spiderwebs, unlike much of the corridor. You did it yourself.

You were in here studying. You had a wall torch lit and a cup of tea on the table. Sitting beside it were various books, most magic based. Right now, you were sat in the chair writing in a notebook of yours. Probably writing information you've gathered based off of the spell books and some of the methods in them that weren't very wand/actually magic related.

Your cloak was hanging loose on your shoulders, not fully put on. And you were focused. A quick hand with swoopy and smoothe hand writing. You came here frequently. But got unlucky this time, perhaps.
