Back at the train, Needles ushered everyone inside. It had been a long day, and he was exhausted. "OK, Doctor Brown," he said. "You get us back to Hill Valley, or else you will have a bullet in your skull."
Doc understood. He nodded, and started up the train. Needles watched him very intently. Jim was watching the other two. He glanced over to the controls for a second, and it was then that Marty made his move. He pulled out an extra sleep inducer that he had kept hidden – just for back-up. He aimed carefully, and used it on Needles first. He was the one with the gun. Jim didn't have his out. Needles fell to the floor, and Marty used the sleep inducer on Jim next. He quickly tried to pull out his gun, but not in time. He fell to the ground, landing on top of Needles.
"Well, that was actually easier than I expected," stated Marty. He kicked the both of them a few times, getting all his frustration and anger out. But Doc stopped him before he could do any real damage.
"Come on, Marty... let's go home. Doc flew the train into the sky and blasted a few thousand years into the future.

Once Dan was safe, and Needles and Jim were placed by the clock tower, (Doc and Marty also conveniently put a few beer bottles by their sides, making it look like they had been 'fooling around' that night, so no one would really take their whole 'time travel' story seriously) Doc and Marty called it a night. Doc drove Marty to his home, but stopped Marty before he went into his house.
"Marty, I just wanted to thank you. You may think you ruined my plans, and maybe you did, but I... I think you redeemed yourself at the end. We completed our mission, even if it didn't turn out the way we expected. I guess that's just how life goes sometimes. And anyway, I think we all need some adventure in our lives."
Marty smiled. This, coming from Doc? He had expected to hear the standard lecture about 'the space time continuum' and the future of the universe. But Doc had decided that tonight, he would just be Marty's friend – not the crazy wild eyed scientist everyone thought him to be. With a final wave goodbye, Doc drove off in his car. He had gotten a new one since the DeLorean – for normal excursions into public.
Marty lay in his bed, listening to the tick-tick of his alarm clock beside him. It reminded him of Doc's house. Doc was a good friend – and always would be. At least, that's what Marty hoped. But who knew what could happen... in the future?

THE END

P.S. Sorry for the extremely lame ending but I'm tired and want to go to bed. Also, I want to be done with this story. I want to move on to bigger and better projects. Well, maybe not better, but definitely bigger. (
