But then again, Wormtail was supposedly in Gryffindor... And he's about as un-Gryffindor-ish as it's possible to be.
He wasn't knitting just a yellow huge cirus-tent-type-thingy. It was a canary yellow huge circus-tent-type-thingy....
And that makes it special.
Let me explain the reasoning behind my Slytherin theory:
As stated above, I do need to re-read Chamber of Secrets(again), but didn't Tom Riddle catch Hagrid in a dungeon corridor? And that's about where the Slytherin common-room entrance is located, isn't it? Or maybe not... Sheesh, I can't even remember where the darn Sly common room is. My own common room!
