- Doc? - Marty!

Doc! Doc!

Marty! It runs on steam!

Meet the family.

Clara you know. Hi, Marty!

Ma'am!

These are our boys.

Jules...

and Verne.

Boys, this is Marty and Jennifer.

Doc, I thought I'd never see you again!

You can't keep a good scientist down.

After all, I had to come back for Einstein,

and I didn't want you to be worried about me.

Oh.

I brought you a little souvenir.

It's great, Doc.

Thanks.

Dr. Brown?

I brought this note back from the future,

and now it's erased.

Of course it's erased!

But what does that mean?

It means your future hasn't been written yet.

No one's has.

Your future is whatever you make it,

so make it a good one, both of you.

We will, Doc.

Stand back! All right, boys, buckle up!

Hey, Doc!

Where you going now? Back to the future?

Nope. Already been there.
