Cortana:
*to you* You should propose to her, Y/N.

You:
I know that Cortana.... it's just... she's different from any of our companions. She's Immortal like you, me, and Tsunade.

((Cortana was given a little bit of Regeneration Energy to make her lifespan last forever.))

Cortana:
If you don't, then I'll tell her myself.

You:
You wouldn't dare!

Cortana:
Then go. And give me some nephews and nieces to spoil, please.

You:
Cortana!!

The human sized AI laughs at her brother's nervousness and his embarrassment.

-Timeskip-

You, Diana, and Cortana leave Earth and the old girl changes her course to a planet where you, Diana and Cortana will meet someone important in your lives for years to come.

In the TARDIS, the Doctor and his companions are clinging furiously to the console as the TARDIS flies violently through the vortex. They are shaking to every possible side while the Doctor tries to regain some control. Sparks are flying, Diana and Cortana are screaming while the Doctor has a look of deep concern.

Diana:
What the hell's it doing?

You:
Controls aren't working!

He tries again with a control and sparks fly. He falls to the floor and sees his hand in the jar bubbling wildly.

You:
I don't know where we're going but my old hand's very excited about it!

Diana:
I thought that was just some freaky alien thing! You telling me it's yours?

You:
Well...

Cortana:
It got cut off. He grew a new one!

Diana:
You are completely... impossible!

You:
Not impossible, just... a bit unlikely!

The TARDIS makes one last rebellious explosion, sparks fly. The Doctor and his companions fall backwards, the Doctor lands in the chair next to the console. The TARDIS has landed. The Doctor looks at his companions before suddenly running towards the door and outside. He exits the TARDIS and looks around curiously. They seem to be in some underground tunnel, littered with junk and old equipment. His companions soon follow.

You:
Why would the TARDIS bring us here?

Cortana:
Oh, I love this bit.

The Doctor is going about his business, seemingly oblivious to the conversation. He licks his hands and looks into the distance.

Cortana:
It's that feeling you get...

Diana:
Like you swallowed a hamster?

At that moment, the Doctor and his companions hear a loud noise. They look over to the source of the commotion. Soldiers are coming.

Cline:
Don't move, stay where you are! Drop your weapons.

The soldiers point their guns at the TARDIS crew who show they are unarmed.

You:
We're not armed! Look, no weapons. Never any weapons. We're safe.

Soldier:
Look at their hands. They're clean.

Cline:
Alright, process them! Him first.

The two soldiers who accompanied Cline move towards the Doctor. They grab him and drag him towards a strange machine.

You:
Oi, oi! What's wrong with clean hands?!

Cortana:
What's going on?

Diana:
Leave him alone!

The Doctor's hand is forced into the machine and he makes yells of pain as it whizzes away doing it's job.

You:
Something tells me this isn't about to check my blood pressure AAGGGH!

Diana:
What're you doing to him?

Cline:
Everyone gets processed.

You:
It's taken a tissue sample. Ow ow ow ow ow ow! And extrapolated it! Some kind of accelerator?

The machine lets the Doctor go, and he moves back, examining his hand. Diana and Cortana run to him while he looks at a larger machine near the 'processor'.

Cortana:
Are you alright?

She examines his hand and notices a Y-shaped graze. The Doctor and Diana keep an eye on the other machine as it opens.

You:
What on earth? That's just...

A woman steps out from the machine, smoke billowing everywhere. The Doctor and his companions look on curiously as the woman looks around, also curious.

Cline:
Arm yourself!

He hands the woman the gun, and she naturally handles it.

Cortana:
Where did she come from?

You:
*look at his right hand and then to Diana* From us.

The woman is arming the gun as the Doctor, looking totally shocked himself, explains the situation to his companions.

Diana:
From us?! How? Who is she?

You:
Well... she's... well... she's our daughter.....

The woman, looks on with a smile on her face.

???:
Hello dad.
