In response to her hard knocks, the desk shook a few more times, and one of the top drawers looked as it it might open up. It didn't, though, in the end.

Hearing Salander's reply, Lexi could only pause and raise an eyebrow in slight confusion. Now just what was the boy on about, hmm? "No, no, not Bo-gart, Mr. Salander--a bog-gart," she corrected. "...and it'll only be a ghost if that's what you fear the most. Now, pipe down and listen--or else I do fear you'll miss what to do when this little guy does come out and pay you a visit."

Lexi eyed Salander just one more time then turned to the class. "Now, several of you mentioned that the charm used to defend oneself against Humphrey Bogart--err, a boggart--is Riddikulus. In saying so, you are, of course, correct," she said. "Does anyone know what two things this charm requires?"

She paused for a second before adding, "The incantation and wand movement alone will not affect the boggart, though. What else must you do in order to defend yourself against this creature?"
