One day you meet the Doctor.

And of course It's the best day ever.

It's just the best day of your life.

Because...

Because he's brilliant.

And he's funny and mad...

And best of all he really needs you.

The trick is...

Don't fall in love.

And I do this trick a lot, sometimes twice a day.

Once you start running...

You start to forget.

Slowly.

After a while, you'd stop asking.

Who are you?

Where are you from?

What's there on your way? where are you going?

Oh, and what is your name?

Yeah, you used to not knowing.

I thought I never would.

I was wrong.

I know who he is.

I know how he began.

And I know where is going.

I know the truth about the doctor and his greatest secret.

The day we went to Trenzalore.

From the beginning she was impossible.

The impossible girl.

I met her in the dalek Asylum, never saw her face and she died.

I met her again in Victorian London.

And she died.

Saved my life both times.

By giving her own.

And now she's back.

And we're running together and she's perfect.

Perfect in every way for me.

Except she can't remember that we have met.

Clara.

My Clara.

Always brave.

Always funny.

Always exactly what I need.

Perfect.

Too perfect.

Got used to not knowing.

And I thought you never would.

I was wrong.

I know who Clara Oswald is.

I know how she came to be in my life.

And I know what she will always mean.

I found out the day we went to Trenzalore.
