Doc: Marty, Marty! Marty!
Doc leaves the garage.
Doc: Marty, Marty? Damn!
Doc tears the price tag off his hat.
Doc: Where is that kid?
Music: Papa Loves Mambo by Perry Combo
Cut to Biff's car. He's driving to the dance. A tunnel lies ahead. Marty gets the walkie-talkie.
Marty: (w.t) Doc, Doc, come in!
Cut to Doc.
Marty: (v.o) Come in Doc!
Doc: (w.t) Marty, Marty, come in!
Cut to Marty.
Marty: (w.t) Doc!
The car enters the tunnel, meaning the radio and the walkie-talkies are cut off temporally. Cut to Doc.
Doc: (w.t) Marty? (normally) Oh my.....
We see what Doc has spotted. It's the DeLorean from Part 1 under the covers! Doc goes over to it.
Doc: Great Scott!
He lifts up the covers and peers in.
Doc: (mumbling) Oh my God.
Cut to the car. The walkie-talkies seem to be working again.
Marty: (w.t) Doc, Doc, come in!
Cut to Doc.
Doc: (w.t) Marty, what happened to you? I went to Biff's house and you weren't there.
Cut to Marty.
Marty: (w.t) You must have just missed me. I'm in the back of Biff's car. He's on his way to the Enchantment Under The Sea Dance.
Cut to Doc.
Doc: (w.t) Marty, listen, we're going to have to abort this entire plan, it's getting much too dangerous!
Marty: (v.o) Don't worry, the book is on Biff's dashboard.
Cut to Marty. The car has just left the tunnel.
Marty: (w.t, continued) I'll grab it as soon as we get to the school.
Cut to Doc.
Doc: (w.t) Marty! You must be extremely careful not to run into your other self.
1955 DOC appears. He makes some adjustments to his "weather experiment." Neither Doc sees the other.
Marty: (v.o) My other self?
Doc: (w.t) Yes! Remember, your mother is at that exact same dance with you! Yeah!
Marty: (v.o) Yeah, this could get heavy Doc.
Doc: (mutters to himself) Heavy, heavy. (w.t) Whatever happens, you must not let your other self see you. The consequences could be disastrous.
1955 Doc: Excuse me, sir. Yes, you with the hat.
Doc (I'll call him 1985 Doc here to avoid confusion) pulls down his hat so his past self won't recognise him.
1985 Doc: Who me?
1955 Doc: Yes, be a pal and hand my five-eighths wrench out of that toolbox.
1985 Doc: Five-eighths? Don't you mean three-quarters?
1955 Doc: Why, you're right.
1985 Doc: I presume you're conducting some sort of weather experiment.
1955 Doc: That's right. How did you know that?
1985 Doc: Oh, I happen to have a little experience in this area.
1955 Doc: Yes, well, I'm hoping to see some lightning tonight, although the weatherman says there is not going to be any rain.
1985 Doc: There's going to be plenty of rain all right. Wind, thunder, lightning. It's going to be one hell of a storm.
1955 Doc: Well, thanks. Nice talking to you. Maybe we'll bump into each other some time again in the future.
