Zip and Oliver were sat in the library, drawing stupid pictures of the other students around them and also talking loudly - when they're supposed to be quiet.

"Hey, dude, why do you look so much like a guy? I thought you were a girl."

Oliver asks Zip, snickering as he continues drawing - he only wanted to get a reaction out of her because he knew that Zip was a girl and he knew how much she hated it when he said that.
