Okay, well, THAT hadn't worked, but you know the old adage: if at first you don't succeed, try, TRY AGAIN. So Toby did that. He tried again. And again.

"Avexis!" The Hufflepuff pointed his wand at the booty, then wriggled to try and see if he could move, AND even stood up to see if the chair might fall away from him on the off-chance that his spells were just having a little 'delay' problem. Maybe he'd already unstuck himself a few times already, and ended up getting RE-stuck.

But no. The chair was staying put. Or... wAIT. WAS IT... HAD IT...?

... It hadn't worked. Toby had thought the chair was finally falling away from him, and it was, but... it had actually started to take his trousers with it. AHEM. Toby sat himself RIGHT BACK DOWN before he accidentally gave anyone an eyeful of his boxers, and pretended like noooooooooooooooooothing had happened. Ahem.

So maybe that wasn't the best method in the world.
