As the hoverboard slowly glided them to safety, Emmett and Clara watched as the Delorean disappeared into a flash of light across Shonash ravine leaving fiery trails extending from the unfinished railway jutting out from the edge of the cliff. Their eyes then looked down at the steaming overheated locomotive falling into the ravine below. As its cowcatcher hit the rocks at the bottom, the tank, cab and coal truck were forced to collide as their potential energy was suddenly removed from them. The burning coals mixed with the additional explosives to erupt into a massive explosion.
"Golly", Clara exclaimed, "I hope Mr. Eastwood is safely in the future!"
Emmett smiled at her as was pleased he would no longer have to hide his true identity from the woman he had fallen in love. "Yes, he should have safely arrived here exactly 100 years from now." Emmett reassured her. Although as he said these words, a passing thought suddenly entered his head. What if Marty's arrival in 1985 had coincided the train schedules? He had had no way of knowing what trains would be passing through Hill Valley at the time he had scheduled the Delorean to arrive.
"It must be amazing!" I have always wondered what the future looks like!" Clara said, "Would you be able to take me there, Emmett?". Emmett was surprised at Clara's reaction. He was certain that this would have been his last journey through time as he had already caused enough damage to the time-line. On his return to 1985, he had intended to destroy his time machine, but he had instead chosen to save Clara from going over the cliff for a second time.!
"Well I thought I would settle down for a peaceful life as a blacksmith in the old West. Time travelling was becoming too dangerous!"
"Oh, but it must be so exciting to travel decades into the future to see beyond one's lifetime. I could go into the past and bring my history lessons to reality!" Clara said as she began to become excited at her future prospects of time travel. Emmett was starting to dread his decision to rescue her as he feared she would constantly try to persuade him to invent a new time machine, not that it was likely that he would be able to accomplish that in this time period.
"Well, let's just get back to Hill Valley and settle down to enjoy life together as blacksmith and teacher," Emmett suggested to steer the conversation away from time travel. He watched Clara's eyes as she slowly brought her mind back to reality and to the man she had fallen in love with.
"That would suit me fine, Emmett! We can leave these fantastical ideas to another day." Clara kissed him and they embraced as they heard another loud bang erupted from the burning locomotive at the bottom of the ravine.
