"That scar, right on his head there was actually the result of abuse from one of his carers. Poor King George III, I expect that's why he went loopy really. Extraordinarily, this is the only portrait to show that scar." The Doctor pointed to a page in the book, but Amy was only half listening concentrating on an interesting light on the ceiling of the TARDIS.

"So, basically he's like Harry Potter?" She asked, trying to liven up the conversation. To her surprise, the Doctor looked confused.

"Harry Potter? Is that a name of a type of pot? Is this Harry a Potter? What has Potter's got to do with George III?" Amy chuckled, not from humour but disbelief. She knew aliens probably didn't read most Earth books, but if he knew of Agatha Christie and others, surely he'd know of J. K Rowling?

"You don't know who Harry Potter is? Seriously, are you kidding?" The Doctor continued to stare at Amy. She raised an eyebrow at him, now shocked into silence and before letting out a 'Eh.'

"Amy, I know I'm extremely intelligent but I don't know everything about Earth culture, potter or otherwise." She shook her head, how could he not know the most well known book/film on Earth?

"Are you seriously telling me that the Doctor has never seen Harry Potter while he's off gallivanting around Earth? Not ever?"

"Oi, you forgot about the massive planet-y rocky thing in the sky on Christmas, why aren't I allowed to forget about something as pointless as a potter?" At this point River came up to them both, her hair wet from the shower.

"Erm, what's going on?"

"The Doctor doesn't know who Harry Potter is." River laughed. "Oh Sweetie, never seen Harry Potter? You're missing out!"

"Who is this person? That you haven't answered me!"

"Harry Potter is a fictional character in a book, coincidentally called the Harry Potter series, that Jo Katherine Rowling wrote. It's the most popular book on Earth from 1997, when it was first published. When the films end in 2011, a lot of 90's kids said it was the end of their childhood." River explained, Amy smiled smugly. If River knows something he doesn't, the feeling of triumph comes across Amy.

"Maybe I do need to read these books."

"Well, does the TARDIS have a Room of a Requirement" A long smile spread across her face. Teasing him was fun.

"Pardon?"

"Because you could get the books, oh and I also require a bed. Maybe you can slytherin?"

"River..?" Amy realised what River was now doing. She tried to keep her laugh in.

"Well darling, I heard that Hagrid isn't the only giant on campus."

"Who?"

"Can I borrow your broomstick?"

"Why?"

"I want to ride it." She couldn't stand it, Amy let out a huge cackle.

"What?"

"You're like a dementor. Feel free to suck my—"

"STOP, RIVER. I HAVE NO IDEA OF WHAT YOU'RE ON ABOUT."

Amy and River fell into fits on laughter, Amy eventually started rolling around on the floor. This was the second time two of his companions and joined in union to make fun of him in ways he did not understand. First Rose and Sarah Jane, now Amy and River. Eventually, River said:

"Well, this has been fun. Got to go and sort out my hair now. See you later…"

"Bye River!" Amy waved cheerily, whereas the Doctor responded with a grumpy, 'Bye.' She was just about to walk up the stairs when she turned around and said,

"Oh and Doctor, you can get your basilisk into my Chamber of Secrets at anytime." Amy exploded with laughter, turning away, River chuckled herself. The Doctor, however, just sat and looked confused. Typical.
