Mercury was out at night, he was pretty bored of pretending to be a visiting school at beacon, so he decided to go out at night behind the school to sit on some park bench, which admittedly wasn't much more interesting. after awhile he noticed you round the corner of the school, to where he was.

"Hey!" He called out. "what you doing all the way here? Don't you know a grimm could snatch ya up at any moment." He says rather arrogantly, he seems pleased that atleast someone's here, much better then looking at the stars blankly.
