There was a knock on the door.

This didn't surprise Koschei much. They were in nineteen sixties London, after all. Someone might have tried the door, found it locked, and then wondered who might be in there when they needed to use the phone. (Human's were self important like that.)

So, of course, he went over and unlocked it, opening his mouth to tell whoever it was to sod off. The word's died on his lips when the curly haired woman hugged him with a very large grin on her face.

"Koschei!" She said happily. "So good to see you again, sweetie. Is the Doctor in?" She pulled back, shutting the door behind her. She was in a flowing red dress that belonged about a decade previous and heels that clicked on the floor with each step. He could see the outlines of a small blaster in her purse.

Koschei blinked at her. "Who are you?"

"It's been so long since I've seen you," she said without hearing him, turning around with an even bigger grin. "Always good to have you in the TARDIS. Has the Doctor been a good boy lately?"

"Has the Doctor…?" Koschei muttered, eyes widening. "Doctor!" He shouted, still eyeing the woman.

The Doctor popped his head in before breaking into a grin. "River!" He shouted joyously. "When did you get here?"

"Oh, just decided to pop by. You need to get rid of that St. John's sticker, sweetie - it gives you away to anyone that knows your TARDIS." She winked at him, a small smirk spreading across her face.

Nodding his head toward the woman Koschei raised an eyebrow at the Doctor. "Who the hell is she?"

The woman -River- cocked her head at him, brow furrowed. "How long have you been in the TARIDS?" She asked. Koschei shrugged, body tense.

"Almost two weeks." he answered. She winced marginally, letting out a hiss between her teeth.

"Oh, not a good time to just drop by then, is it?" She winked at the Doctor, turning for the door. "See you later, sweetie."

And she was gone.

"Who the hell was she?"

A/N: I'm getting increasingly happy with these. ^_^ Honestly it's quite odd. Usually I get less happy with my work as it progresses. Maybe it's because it's just in the same 'verse and not in any way chronological order? It does make me stress a bit less about them.

Hope you guys enjoyed!
