Marty slammed on his 4x4's brakes as Doc Brown ran into the driveway just as Marty pulled out of the garage. Leaning his head out the window, Marty shouted, "What're you doing, Doc? You're gonna get yourself killed!"

"Marty!" cried Doc. "Come with me! It's a matter of life or death!"

He looked at his girlfriend Jennifer in the passenger seat with a sheepish smile. "Sometimes I help him with... stuff." Marty climbed down from the truck's cab. "What is it, Doc?"

"Remember the DeLorean? I need to take you on a trip."

"Aw, Doc, I'm taking Jennifer up to the lake. It's gonna be romantic."

"I'll have you back in ten minutes," Doc said. He leaned around Marty and waved at Jennifer. "I'll have him back to you in ten minutes!"

One 88 mph trip later, Doc and Marty stood looking at a landscape: pastoral and natural, but from the floating city in the distance, obviously a distant future. After some time spent in silent awe, Marty said, "What're we doing here, Doc?" Not getting an answer, he turned to see Doc Brown back behind the wheel of the time machine.

"This is a utopia, Marty! No one goes hungry, people live 200 years, everyone gets to pursue their passions! Enjoy it, Marty! You'll fit right in!" Marty's response went unheard for the 15 seconds the DeLorean took to reach hit 88.

Back in 1985, Doc Brown watched through binoculars as Marty McFly arrived from 1955, stuck in the new timeline he'd created, in which a Marty McFly-shaped hole had just been made. It wouldn't do for there to be two of them.

Marty looked at the Toyota 4x4 with wonder in his eyes. He turned with a grin when he heard Jennifer say, "How about a ride, mister?"
