Koschei 7

I'm thinking of adding some other past companions. Who should I add? I own nothing!

Koschei and the Doctor wandered through the halls of the TARDIS.

"You do know that you can find any room by just pressing a button on the TARDIS console. It's just a simple button!" Koschei whined.

"But there is more adventure this way!" the Doctor walked a little faster.

"You never change." the younger stated blandly.

"No," the Doctor shook his head.

"What do you think the humans are doing?" Koschei asked.

"Amy and Rory are probably kissing. Jack is probably flirting, and Martha and Mickey are probably chastising him." the elder said immediately.

Meanwhile...

Amy and Rory were kissing. Jack was flirting, and Martha and Mickey were chastising him.

"You can't flirt with every girl you see." Martha sighed.

"Even more so if she's already making out with someone!" Mickey continued.

"Sorry, but where does the Doctor find them? I need to know his ways." Jack didn't seem bothered by the two.

"I'm sure he wouldn't tell you even if you asked. Just think of it..." the other male had a startled look on his face.

Martha just laughed.

"So, how do you think the Master acts in his petite form?" Mickey questioned.

"He's probably plotting to take over the world." Jack decided.

"What if he isn't? What if he hadn't started being incredibly evil yet?" Martha looked between the two boys.

"Hmmmm," the immortal man stroked his chin, "Now that is the question,"

"We found it!" Koschei bounded down to the level everyone was on.

"Found what?" Amy questioned.

"The library!" the Doctor looked equally excited.

"Okay," Rory just nodded.

"Can we go somewhere?" the ginger whined. "It's boring here..."

"All right, come along Ponds!" the eldest Time Lord bounded to his TARDIS' console.

The humans crowded.

"Where are we going?" Jack inquired.

"I'm setting the dial on randomizer. Only this time it will be somewhere I've been before." the Doctor added.

"Isn't it dangerous? You could see and meet yourself..." Jack looked at the Doctor seriously.

"But that's the fun part! We get to play the avoiding game!" the Time Lord thought a little. "There is also a good chance that we could find one of Koschei's companions."

"Do it," Koschei said immediately.

That's all the Doctor needed.

"GERONIMO!"

Tell me, which companion should I add next? Review!
