Officer Reese: You got a little tranked, but I think you can walk.
Officer Foley: Ma'am, you should reprogram, it's dangerous to enter without lights on.
Jennifer: Lights on?
The lights turn on!
Officer Foley: yes, now look. Just take it easy and you'll be fine. And be careful in the future.
Jennifer: Future?
Officer Foley: Have a nice day Mrs McFly.
The officers leave. Jennifer looks around. Upstairs, a teenage girl, MARLENE, can be seen walking around. Jennifer looks at a window, there's a picture of a nice garden.
Computerised Voice: (v.o) Broadcasting beautiful views 24 hours a day: you're tuned to the Scenery Channel.
Jennifer: I'm in the future.
Marlene: (o.s) Mom, mom is that you?
Jennifer sees some photos and has a look. One is of her wedding.
Jennifer: (horrified) I get married in the Chapel of Love? I've got to get out of here!
She goes to the front door and looks for a doorknob - of course there isn't one. Then the doorbell rings. Jennifer steps back, spots a closet and hides in it. Marlene McFly comes down the stairs. She's Marty's daughter, and looks like a female Marty.
Marlene: Mom? Mom, is that you?
She opens the door. It's Grandma LORRAINE, 77!!! Lorraine has grey hair and is much wrinklier, but is still in good health.
Marlene: Grandma Lorraine!
Lorraine: Sweetheart!
They kiss.
Marlene: What happened to Grandpa?
Lorraine: Oh, he put his back out again.
She steps back to reveal 77 year old GEORGE. He's attached to a hovering device and is upside down. He too is in good health.
George: How's Grandad's little pumpkin?
Marlene: How did you do that? How did he do that?
George: Oh, out on the golf course.
Lorraine: Are your folks home yet? I bought pizza for everyone.
Lorraine holds up the pizza - its only a few inches long!
Marlene: Oh, who's going to eat all that?
George: Oh, I will!
Cut to the DeLorean on the skyway.
Doc: Damn this traffic! Jennifer, that is old Jennifer, usually gets home around now. I hope we're not too late.
Doc looks through his goggles.
Marty: What is it, what's the matter Doc?
Doc: For a moment, I thought I saw a taxi in my rear display. I thought it was following us. Weird.
Back at the McFly house, Lorraine is changing the scenery on the window.
Lorraine: I can't believe this window is still broken.
She changes it from an Eastern garden to a sunset to New York at night (with the World Trade Center towers!) to a mountain.
Marlene: Well, when the scene screen repairman called Daddy a chicken, Daddy threw him out of the house and now we can't get anybody to fix it.
Lorraine: Look how worn out this thing is!
Lorraine lifts it up like a blind to reveal the real window with next door shown through it. Cu to Jennifer in the closet as she listens to.....
Lorraine: (o.s) Your father's biggest problem Marlene is that he loses all self control when someone calls him chicken. How many times have we heard it George?
Cut to George and Lorraine.
Lorraine: Mom...
Lorraine/George: .....I can't let them I'm chicken!
George: Well, you're right, you're right!
Lorraine: About thirty years ago, your father tried to prove he wasn't chicken and he ended up in an automobile accident.
Marlene: Oh, you mean with the Rolls Royce?
Cut to Jennifer.
Jennifer: (horrified) Automobile accident?
