Draco went to London on a dare. No wand, no broom, no Floo powder, just some Muggle money (fifty pounds) in his pocket and Harry's words ("you'd be lost, Malfoy") ringing in his ears.
He wasn't lost. He had only to stay for the afternoon. But he had to buy something, or nobody (Harry) would believe him.
Draco joined a queue, bought a ticket for some sort of play. The stub would do for proof.
The lights went down. The curtain rose. The trailers rolled. The movie started. Draco's mouth dropped open.
Three days later, Draco was still in London.
FINIS
Really.
It seems like most of your HP fic has come recently. That means you're currently obsessed? I really frickin' hope so.
I have wondered a lot about wizards and the muggle world. This was sort of like a tiny hit of crack for me because of that.
I could see the look on Draco's face when the movie started. lol
