"You do know that Jo Rowling and her children are the descendants of the Zakians from Delta-Zygorg point nine-oh-three-two-six don't you?" The Doctor nudged Rose, who was immersed in the last Harry Potter book.
Rose looked up. "Seriously?"
"Nah, but it got your attention though didn't it?"
Rose rolled her eyes. "What's that?" she asked, nodding to the package in his hands.
"Found this, thought you might like it," he chucked a DVD at her: Harry Potter and the Goblet of Fire.
"That bloke, Barty Crouch Jr." The Doctor frowned later.
"What about him?"
"Just.. Something about him."
"He was quite handsome. You know, for a crazy bloke." Rose smiled.
"He seems familiar. Can't quite put my finger on it." The Doctor shrugged. "Oh well."
And they strolled on to their next adventure.
