Cut to the Starlighters at their car.
Marvin: Give me a hand, Reginald.
They manage to get the door open. But Marvin hurts himself.
Marvin: Ow, dammit, man, I sliced my hand!
Marty: (re: keys) Whose are these?
Reginald: Mine.
Marty gives them to him.
Marty: Thanks, thanks a lot.
Cut back to George, Lorraine and Biff at the car.
Lorraine: Stop it, stop it Biff! You're gonna break his arm! Stop it!.
Lorraine jumps on Biff.
Lorraine: Biff, leave him alone! Let him go! Let him go!
Biff pushes her off and laughs. George clenches his other hand into a fist as Biff continues to laugh. Then, when Biff is unaware, George hits him 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.
George: Are you OK?
He helps Lorraine up and they walk hand in hand to the gym. A crowd, including Marty, has developed.
Girl in Crowd: Who is that guy?
Boy in Crowd: That's George McFly.
Girl in Crowd: (disbelief) That's George McFly?
Marty looks at the photo. Linda is still disappearing, everything isn't fixed yet!
Marty: Excuse me.
Cut to Doc at the Courthouse. He's fixing up his equipment when he hears thunder in the distance.
Doc: The storm!
Cut back to Marty. He's with the Starlighters. Marvin's hand is bandaged and they're making sure he's OK.
Marty: Hey guys, you gotta get back in there and finish the dance!
Reginald: Hey man, look at Marvin's hand. He can't play with his hands like that, and we can't play without him.
Marty: Yeah well look, Marvin, Marvin, you gotta play. See that's where they kiss for the first time on the dance floor. And if there's no music, they can't dance, and if they can't dance, they can't kiss, and if they can't kiss, they can't fall in love and I'm history.
Marvin: Hey man, the dance is over. Unless you know someone else who could play the guitar.
Cut to inside the gym. Marty is on stage playing Marvin's guitar. Marvin looks at him, is impressed with his guitar playing, and then heads for the microphone.
Marvin: This is for all you lovers out there.
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.
The song continues as Marty looks at the photo. Linda is now gone. Cut to George and Lorraine dancing.
Lorraine: George, aren't you gonna kiss me?
George: I, I don't know.
A bully, DIXON, approaches. He's one of the guys who was kicking George earlier.
Dixon: Scram, McFly. I'm cutting in.
He pushes George aside and starts to dance with Lorraine. George walks away. Cut to Marty. His playing isn't too good.
Reginald: Hey boy, are you all right?
Marty: I can't play.
Cut to Lorraine.
Lorraine: George! George!
Cut to Marty. He's starting to be erased! Looking at the photo, Marty sees himself starting to vanish. Marty then looks at his hand and sees it is starting to vanish.
Marty: (weakly) George.
George pushes Dixon aside.
George: Excuse me.
George pushes Dixon away from Lorraine and they look at each other. Then George and Lorraine kiss. Suddenly Marty stands upright again. He's saved! He looks at the photo. First himself, then Linda, and finally Dave reappear. The future is saved! Meanwhile Marvin finishes the song.
Marvin: (singing) The vision of your happiness, whoa, whoa, whoa! Earth Angel, Earth Angel, will you be mine? My darling dear, love you for all time. I'm just a fool, a fool in love, with you.
The dancers cheer.
Marvin: Yeah man, that was good. Let's do another one!
