The first teleportation hadn't quite gone as planned, no sir! Not at all like planned. The second teleportation had actually sent him to the school grounds this time. The fellow clad mostly in green was dripping with water - like he had decided to go for a spontaneous swim or something like that. Loki came to the conclusion that he had teleported outside the correct classroom even! As he calmly removed the headpiece/tiara/crown of his and ran his fingers through the dripping wet hair he took a moment to look at the people around himself - he was a he, right? A quick glance of self examination verified that he indeed was.

There were a lot of people present - one of the fellows had a cool coat - not as cool as his own though, but still passable. Loki glanced around and did his best to be as inconspicuous as possible while leaning against a wall and doing his very best to seem like he had been there all along - instead of just appearing out of nowhere and in doing so breaking school rules. So he just remained there, dripping water.
