"McKendry? Alyssa McKendry you're sure?" Sara had stood up and began pacing.

"Of course I'm sure. Why? Do you know her?"

A huge smile crept across Sara's face. "Hell yes I know her." She began to collect her things, putting the strap of navy purple book bag over her right shoulder, and holding the book in the crook of his arm. "Let's go"

The Doctor started. "What do you mean go? Go where?" This wasn't how this went. People didn't tell him where to go. It was the other way around.

"Where do you think?" Sara scoffed, walking with long strides to the TARDIS.

The Doctor's eyes grew wide when she walked right up to the blue box, opened it, and walked in, just like that.

"How did you..? TARDIS never just lets new companions in. Ever." He walked in after her as she made her way to the consul, carefully walking in a circle around it.

"Doctor, she went out of her way to send my book from the library. I think she likes me." She said before stepping forward and deftly begin to flip switches and type on the screens.

"Wait, your book?"

"Yup. Has my name in it. I didn't write it. Not my handwriting, not my ink, but definitely my name. Been there for thousands of years from the looks of it. See for yourself" She stepped away from the consul, (which the Doctor noticed she had set to leave for Alyssa's house to perfection) grabbed the book, and handed it to him "front cover."

Then she went over and flipped the lever.

***
She wasn't lying. The Doctor flipped over the front cover and right there, in fancy calligraphy, was Sara M Johnson. And it definitely wasn't fresh.

Meaning it was meant to be hers thousands of years ago.

As if this whole thing wasn't weird enough.

Alyssa had heard the TARDIS before it materialized in her driveway. So she was standing there, arms crossed, expecting the slow fading in of the blue box, expecting the Doctor to pop out with a look of adventure on his face and a new time or place to save.

She wasn't expecting for him to walk out looking rather confused, and she definitely wasn't expecting her best friend to walk right out behind him.

Sara was looking the same as ever, confident look on her face, also somehow managing to look like an excitable seven year old. She had a book in the crook of her arm, as to be expected.

Her hair was down. So today was a good day-in the whole 'convert Sara into an actual girl and not some genius skater futbol chick' regard. Jeans and a t-shirt. Regular attire.

Still doesn't explain what she was doing on the TARDIS though…

She did however, skip right past the Doctor, who shook his head as she came right over to Alyssa and placed her things on the ground before crushing her in a hug. Alyssa wasn't tall by any means, but Sara was at least 5'7", 5'8", so hugging her always made Alyssa feel really short.

But Sara Johnson gives the best hugs, so it's worth it.

Alyssa laughed and pulled away from Sara, facing the Doctor, confusion evident on her face. Almost mirroring his.

"Quite some friend you've got there, McKendry." he said with a small smile, and Alyssa heard Sara snort.

"Yeah, lord knows why I keep her around."

Now Sara full out laughs. "Because if you didn't who else would keep that innocent mind of yours from making a fool of itself?"

Alyssa chuckled. "That's true," she turned to the Doctor. "So the question is, where did you find her?"

"Library" he shrugs

Alyssa laughs "I should have known"

"Shall we enter your humble abode?" Sara asks in a posh fake British voice, before grabbing her things off the ground, not waiting for an answer, and simply walking up the driveway and into Alyssa house.

The Doctor shakes his head. "Does she do that often, just walk into people's homes?"

Alyssa shrugs, "Pretty much. Who need permission when you have a door, right?"

He scoffs, shaking his head at the sky as if to ask what have I gotten myself into? "Yeah, she's…something"

Alyssa laughed. "Bloody Americans."
