Emma and Marty were able to hitch a ride all the way to the center of town after spending the night at a small hotel on the outskirts of town. Downtown looked totally different from the Hill Valley they had known all their lives; there was a kid hopping around in what Grandpa Marty had told them was moon shoes and there was a sign by a theater advertising air conditioning like that was something new. But, they then remembered, back then it was new. They looked up and saw that the movie the theater was playing was starring Ronald Reagan.
"Wait a minute. Ronald Reagan? He was an actor?" asked Emma.
"I didn't know that either. Good thing Jerry Lewis never went into politics, he was real popular around this time too. At least that's what Grandpa Brown told me," answered Marty.
They knew that the first thing they should do was to go find Marty's Grandpa and they decided to go into public station that might have a phone book. There was another teen about their age who walked in a hurried pace past them and into a restaurant called Lou's and they followed him, hoping that he would know his way around. They went in and the other teenager walked over to be with who they assumed was his friend, but the other one looked kind of weak and shy. She watched him ask who she figured was Lou and the scrawny one got a chocolate milk while his mystery friend sat at the counter. Emma and Marty sat up at the counter and were just about to ask him if they knew a Doc Brown when a big guy came through the door with three guys behind him.
"Hey McFly! I thought I told you never to come in here." said the big guy.
"I don't even know you. You can't tell me where to go!" said Emma.
"Who the hell are you? I'm talking to McFly over there. Well, what have you got to save for yourself, McFly?" he said again.
"I am a McFly. Emma McFly. Who are you and why are you bossing people around?" asked Emma.
"Em, don't. Let's go find Grandpa Brown by ourselves," said Marty.
"I don't have to tell any butthead who I am or why I'm doing something. And what do you mean 'Grandpa Brown'? That old man has kids? Probably bastard children cause he ain't married. Ha ha." he said to Marty and Emma.
"Jesus! You must be Biff Tannen!" said Marty, realizing that getting angry wouldn't be helping things along. He had heard stories about what Biff could do.
"Yeah and what's it to you? Just make like a tree and get out of here!" said Biff.
"Hey! I asked you a question. What gives you the right to boss people around?" asked Emma, poking Biff in his chest.
Marty McFly tripped Biff up before he could get to this strange girl who claimed to be a relation to him. When he fell over and got knocked out on a booth everyone heard:
"Isn't he a dream boat?" gushed a girl that looked extremely familiar.
"Marty! That's my Great-grandma Lorraine!" said Emma in an excited whisper.
"Maybe your Great-grandpa George is around here too," said Marty.
"It must have been the guy on the skateboard. Let's follow him to his house and try to get to know him and see if he knows Grandpa Brown," answered Emma.
"Yeah, he's walking over there, let's go,'' he answered.
Inside Doc's House
"Doc, we have a problem! I was at Lou's with my Dad and these two kids show up and one of them said that they were a McFly and the other said they were looking for their 'Grandpa Brown'. Maybe they're from the future!" said Marty.
"Great Scott! Now we've got three kids from the future! Marty, we can't tell them who you are; if they know too much it could alter the space-time continuum and unzip the fragments of time itself resulting in a paradox!" answered Doc.
"This is heavy. Doc, how can we fool our own family?" asked Marty.
"We don't know that for sure, but I still want you to be under the guise of Calvin Klein to avoid any confusion," said Doc.
"You're the Doc, Doc," was his reply.
Back outside
It turned out that they weren't following George, but they were actually following Marty McFly! They followed him all the way to Riverside Drive and knocked on the door after he'd gone inside.
An old man opened the door. "Can I help you?" he asked.
"Is George McFly in there? I need to ask him if he knows a Doctor Emmet Brown. He's my Grandpa and we've had some…car trouble and he can help us," answered Marty.
Doc was shocked to see that Marty had been correct about the new kids. "Great Scott! Get inside! Quickly, quickly!" he said.
They walked over to the boy in suspenders and asked him, "Are you George McFly?"
"N-no, I'm Mar-Calvin Klein. Who are you?" asked Calvin.
"Well, I'm Emma McFly and this is Marty Brown. We're looking for Marty's Grandpa. His name is Doctor Emmet Brown. Do either of you know him?" asked Emma.
Doc and Marty shared a look. How much did they know and where did they come from? Where they truly from the future? They decided to take the chance and ask them. Besides, Doc wanted to know if this was really his granddaughter and Marty wanted to know if this was his grandson.
"Ah, where are you guys from?" asked Marty from 1985.
"We're from—"started Emma when there was another knock on Doc's front door. This time it was Lorraine.
