Marty: (w.t) I dunno!
Doc: (v.o) Well, do you have any idea where he is?
Marty: (w.t) No, he could be anywhere by now!
Cut to Doc.
Doc: (w.t) Marty, the entire future depends on you finding Biff and getting that book back!
Cut to Marty. Outside, Biff gets out of the car. George tries to punch him, but Biff grabs his arm and twists it, causing George to let out cries of pain.
Marty: (w.t) I know! I just don't know where...
Lorraine: Stop it, stop it Biff! You're gonna break his arm! Stop it!
Marty has heard her this time!
Marty: Of course! (w.t) I gotta go, I got one chance, my old man's about to deck Biff!
Marty runs outside. George hits Biff in the face. Biff falls down to the floor. George looks at his fist with a "I can't believe it! I did it!" expression and then turns to Lorraine.
Marty: Yes!
Student: (o.s) There's a fight over here, come on guys!
Marty: Talk about deja vu.
George: Are you OK?
He helps Lorraine up and they walk hand in hand to the gym. A crowd, including 1955 Marty and the WALLET GUY (the reasons for this name will soon be revealed), has developed. 1955 Marty checks his photograph and runs off. 1985 Marty goes over to Biff once his parents and 1955 Marty have left.
Marty: OK everybody, let's back up now, huh, let's backup, just everybody back up. Give him a little bit of room, OK, a little bit of air. It's OK. I know CPR, (to Wallet Guy) I know CPR.
Biff is beginning to wake up.
Biff: Hey...
Wallet Guy: What's CPR?
Biff wakes up and looks at Marty.
Biff: (to Marty) You!
Marty punches him again - he falls unconscious. Marty takes the Almanac out of Biff's jacket.
Marty: He's fine.
Marty runs off.
Wallet Guy: Hey, did you just take his wallet? He just took that guy's wallet!
Cut to Doc at the DeLorean. Marty can be heard through the walkie-talkie.
Marty: (v.o) Doc, success, I got it!
Doc: Thank goodness. (w.t) Great Marty, as soon as I reload the fusion generator, I'll meet you on the roof of the high school gym.
Cut to Marty.
Marty: (w.t) On the roof, 10-4.
Marty turns the corner to meet up with Biff's gang.
3-D: Hey, it's him!
Skinhead: And he's in disguise!
Marty: Guys, what's that?
He points in the other direction, they turn and look, and he pushes past them like he did with Griff's gang in 2015. Marty runs off. The gang gets up.
3-D: Come on, let's get him!
Meanwhile the DeLorean takes off and accidentally hits the Lyon Estates billboard.
Doc: Damn!
He accidentally turns the time circuits on, and the bump causes the Destination Time to turn to JAN 01 1885 12 00. Doc doesn't notice though. The DeLorean flies off with a flag pennant attached to the rear wheel. Meanwhile Marty enters the dance. MARVIN BERRY is on the stage singing. 1955 Marty is also there, playing the guitar, and George and Lorraine are there dancing.
Music: Earth Angel by Marvin Berry & The Starlighters
Marvin: (singing) Earth Angel, Earth Angel, will you be mine? My darling, dear, love you all the time.
George waves to 1955 Marty up on the stage. 1955 Marty waves back.
Marvin: (singing) I'm just a fool, a fool in love, with you.
George and Lorraine kiss. Biff's gang enter the dance and Marty hides underneath a table, his hat falls off and he grabs it just in time.
Marvin: (o.s) Let's do another one!
Skinhead: Where'd he go? He just came in here?
1955 Marty: (o.s) Something that really cooks.
3-D spots 1955 Marty on the stage about to play Johnny B Goode.
