As per demand...
Greg asked for the plateau on their first day back at Hogwarts and thusly, I present this!
The unofficial fifth house of Hogwarts: the Plateau.
I think who is who is obvious, but if you can't figure it out, the text following the picture should clarify.
I imagine the conversation going thusly:
Leslie [G]: And with one fell placement of the x, I'll be taking fifty points. Wait, no--fifty-two.
Jamie [S]: I think she plays better upside-down.
Mikey: [R] Yeah, yeah, whatever...*mutters darkly*
Nicole [H]: This is Yami!
Greg [H]: Not in the face!
Karla [R]: *is absorbed by the fascinating writings of O. RLY, an ancient wizard who excelled in the arts of deception, disguise and general sneakiness*
Oh, and when I next see you, Greggo--you get the original. Hope you like it.
[Edit: For clarification, the guest stars in the picture are Nicole's future cat Yami and Karla's bunny Felix. Yeah, screw the whole "only an owl, cat, toad or rat" rule. Canon? Whazzat?]
