Marty pulled Jennifer closer to him and smiled as the ELB locomotive began to fly over the tracks and then vanished into time, leaving only a trail of fire.

"Do you think we will see them again, Marty?" Jennifer asked holding Marty just as tightly as she was being held.

"Yeah I suppose so. The doc isn't just going to vanish forever. I'm sure he'll be back before you even begin to miss him too much".

Pleased with his answer the couple turned and stepped over the wreckage of the De Lorean towards his shiny polished truck.

A breeze blew down the tracks, not strong but eerie enough to stop Marty in his tracks and have him look back one last time.

"Marty, what is it?" Jennifer asked and grasped his arm gently.

"Did you feel that? It was strange, like something is happening".

"Marty", the voice was faint and distant, like an echo being carried on the wind.

"Did you hear that?" Marty looked her straight in the eyes and gripped her tighter.

"No, Marty, I didn't hear anything", she shook her head, "It's just the wind".

The pair began to move towards the car when he heard it again, "Marty", it was louder this time and more urgent.

"I definitely heard it that time", he spun around to stare at the tracks that only a moment ago rested the locomotive that carried Doctor Emmett Brown and his family.

"I heard it too", Jennifer gasped.

"Marty!" this time a hand clasped his shoulder and turned him to face the form of Doctor Emmett Brown. Clearly out of breath he had to double over while his friends were left to be shocked.

"Doc!"

"Doctor Brown?"

"Doc, I knew you were coming back but this soon? You just came back from the future and you went away again".

Doc stood up straight now, rigid like a bolt and with an all too familiar look in his wide eyes.

"I know, I know but I'm back from the future now, Marty and I need your help again"

"Doc this is getting old"

"So am I, Marty but this could be more crucial then anything you have ever done for me before. This is about the whole space time continuum".

"I'm sure we could find a way to help, Doctor Brown", Jennifer told him with a concerned look on her face.

"Good. Now, first things first, who knows how to drive a locomotive through time and space at 88 miles per hour while keeping a steady altitude. No? Then I guess I'll drive"
