I didn't create Buffy the Vampire Slayer or Doctor Who, I'm just playing with their characters for my enjoyment. Don't sue :)
"I have a favor to ask of you."
Giles had been intently reading another prophecy book in the library. He looked up to see a man in a brown trenchcoat and converse shoes.
"Do I know you?" Giles asked, surprised. He didn't remember hearing anyone come in.
"Yes, you do, Rupert Giles of Oxford. Although I had a different face before."
"Different face?" Giles stood up to clean his glasses.
The stranger grinned. "I know why you do that."
"If you don't tell me who you are," Giles said as he put his glasses back on, "I will have to ask you to leave."
"C'mon, Rupert. Rupie. Can I call you Rupie? No, I wouldn't think you'd like that."
"You certainly know how to be irritating. What do you want?"
"Last time I saw you," the stranger replied, "you were training a girl. A cheeky little blonde with a lot of spunk."
"Perhaps."
"Do you know where I can find her?"
"Perhaps. I have a favor to ask of you first."
"I know, I know. Don't get all timey-whiney on me." The man walked over to the window and opened the blinds. "It's outside."
"What's outside?" Giles wondered, walking towards the window. He looked out to where the man was pointing and was speechless for a moment.
"Remember now?"
Giles turned to the man, still in shock.
"You're the Doctor."
