"You can call me… sexy."
"Only when we're alone!"
"We are alone."
The words run around the Doctor's head as he works under the TARDIS consol, Koschei half-asleep just meters away in the chair.
"Only when we're alone!"
They were alone now, right?
"Koschei," he said suddenly. The younger Time Lord jolted up, blinking the fogginess from his mind.
"You can call me Theta."
"What?"
"Only when we're alone, I mean."
A pause.
"And variations thereupon?" Koschei asked curiously.
"Of course. I call you Kosch, don't I?" The Doctor grinned up at him through the glass floor.
"All right then, Theet."
