Louis wandered the castle aimlessly, it would soon be time to head back to Slytherin. He quietly made his way through the empty, dimly lit corridors. His head angled down as he walked. A few students would pass him, not sending him so much as a glance. He made his way up to the astronomy tower. Going up the stairs before pausing at the top. Another student was there, at this time? How strange.. Their back was facing the Slytherin, so he couldn't see who they were.

"Hello?" Louis called.
