"Let's move over here," Doc advised, so they could talk freely without being overheard again. He, Marty, and 1955 Biff all went off the Mcfly's driveway and onto the sidewalk. "Now we won't risk anyone else recognizing you, Biff, and we can plan our next move."

It was an otherwise quiet Saturday morning, but still Doc didn't want them to get any more attention, so he wanted to get this done quick. Biff than spoke up.

"Look, just tell me, punk, how could you have been George Mcfly's son and still been in 1955?"

Marty just said, "Hey, Biff, don't worry about it. I'm Calvin, but my middle name is Martin and I just like the name Marty better than Calvin you see." He chuckled at his own comment as he thought of the next thing to say. Though he was visibly anxious, one thing he was good at was thinking of things to say in a tight situation.

"I am from 1985, but I'm not George & Lorraine's son. I'm just close with them, that's all. People always mistake me for their son, who they really did name Marty. I kinda look like him, that's the thing."

Marty was running low on stories in the past week or so. Luckily for him, Doc interjected .He wanted to preserve the space-time continuum, and knew the more Biff remembered about visiting 1985, the more effects it could have later. This couldn't have been clearer than when Biff himself mentioned something about it.

"I just want you both to know that I still owe this guy a few punches. Just 'cause I'm in the future, that don't mean I've forgotten it. I'll tell you what, you both let me take back something to 1955, and I'll cut you another break."

The pair got a bit worried, Doc in particular. "Just what is it you're planning to take with you? If you take a certain device suited for this time period and it gets invented before it did in this timeline, that could disrupt the space-time continuum!"

Marty knew how dense Biff would be to scientific information like this, because he could be too. "English, Doc."

"What I mean is let's say something didn't get thought of until 1970. If you take it to 1955 and someone discovers it, the future could turn out differently."

Biff did understand this, but thought he'd give it a try anyway.

"Well, uh, you see, I was at this big place called a mall this morning. I went into some record store and got this album some nice guy named Needles told me about. He also told me you were a chicken!"

Both realized that his interactions were more than they would've guessed and that wasn't good.

"Biff, what the hell were you doing at the mall this morning?" Marty almost demanded to know.

Biff got madder as he told Marty. "Well, butthead, I woke up right outside the theatre downtown. This bum told me about where you lived, and about Brown. I didn't knew how the hell to get here, and I figure I'm only gonna be here once, I wanna see what the mall is. I'd heard about it. Than, I was hitchhiking and ended up there, it's close to here anyway you know!"

"Jesus, just tell me what you've got with you?"

"Yeah, it's some device instead of records. Some big popular rock & roll guy from this time. His name is Huey Lewis. I heard some song of his, it was good, and I just wanted to let the guys hear it. Needles let me shoplift it, too, what the hell?"

Than he went into his slightly evil sounding laugh he did when he thought he was right. "Ha, ha ha ha!"

Doc took over. "That is completely out of the question. What if somebody hears the song, likes it and decides to record it or get it out in the public. That means when the new 1985 rolls around, Huey Lewis might not record it himself. In fact, let's say it gets heard, than he hears 'Heart & Soul' when he's growing up, gets inspired by it and comes out with a different album. This means when this version of you shows up in 1985 again, you'll bring back a different album, and if you do that, it could unravel the very fabric of the space-time continuum and destroy the entire universe!"

Biff just got the hint of what Doc said to know that the answer was no. "Look, what if I just keep it to myself. I'd like to have some different music. I'm into Perry Como, but this 1980s stuff sounds like 'Rock Around the Clock' just louder or something. Hell, there's even a picture of this guy at a pool table on the cover."

Marty knew that too would be pointless. "You're gonna need something to play it on, you know. I have a record of that album, but I'm not letting you have it. You heard what Doc said might happen if somebody hears it you know."

Biff handed the still plastic wrapped cassette over to Marty than said "Yeah, okay fine. What about you just let me get another look at Lorraine. She might be getting old, but she sure as hell looks hot as in 1955! If I do anything, I won't have to worry about getting caught for another 30 years. Than I'll know so I'll just be out of town when this day comes around normally!"

This made Marty visibly angry. "Don't talk about my mo, I mean, Lorraine that way, you son of a bitch, you got that!"

Doc had turned to get something out of the DeLorean at the time. He heard this and told Marty to relax, but knew he was right. Anybody normal would react that way to what Biff had said. "I've got a foolproof plan, but it will involve everyone's cooperation."

"Oh, yeah, what could that be, crazy old man?"

Biff was looking straight at Doc. He had some device that was very futuristic beyond 1955 in his hand that he'd gotten from the car. He pointed it in Biff's face and he fainted and fell against some bushes.
