Slipping in, Xavier took advantage of the humidity, sure that if the greenhouse was hot enough, sweat in the eyes or haziness could hide his form. Hands in pockets, he looked over some students shoulders, attempting to remember doing this lesson. Peering over the shoulder of one boy who didn't look happy, he wondered if the guy had completed his assignment already.
He'd seen nothing but night projects to his memory, although how the students passed Herbology he'd had no clue. He did remember a few singing to their projects at night though. Was that supposed to be part of the instructions?
I may haunt the halls of Hogwarts, but never you.
