After getting that mysterious letter (alright, maybe not that mysterious) from her serpent sidekick, Sierra, Nora was simply excited and curious to find out what her fellow Slytherin had in mind.

So, just as the letter said, the girl made her way to one of those empty classes, classroom eleven, and scanned the room, since she knew Sierra from other classes and from the Quidditch matches.

But... what if she wanted to play a prank on Nora?

... it was already too late to escape, eh?
