Some really hot girl had a slutty Harry Potter costume on. I'd like to put my Basilisk in her Chamber of Secrets if you know what I mean.
Unless the Chamber was built around it. Then it would have simply been inside for as long as the Chamber of Secrets has been around.
So wait, some girl was dressed up as Harry Potter and you want to do her? Sure dude, whatever floats your boat.
Well the point is that you want to bang that Horcrux, right? So why do we need to sugercoat it with all these innuendos?
You're gonna lose your beloved Basilisk once 'she Harry' gets a hold of Gryffindor Sword from your friend.
Hopefully she's not too ****ty, wouldn't want that Chamber of Secrets to be a Goblet of Fire. If you know what I mean.
