On October 26, Marty had returned from 1885, and had safely crossed the Eastwood Ravine bridge in the DeLorean time machine. Before Marty had a chance to react, a diesel locomotive hit the DeLorean and broke it into several pieces.
On October 27, Douglas J. Needles dared Marty to compete in a drag race by calling him chicken. Marty learned in 1885 that his ancestor, Martin McFly, died because he was insecure about being called a coward. Not wanting to share his fate, Marty decided to not let Needles get to him, and backed up his truck instead of racing him.
Needles narrowly missed hitting a Rolls-Royce Silver Cloud III, and Marty realized that if he had raced Needles, he would have hit it. Jennifer Parker, who had picked up a fax in 2015 stating that the middle aged Marty had been fired from his job, witnessed the text on the fax being erased from existence.
Marty and Jennifer then traveled to the site of the destroyed DeLorean. Marty found the photograph of Doc and himself in front of the clock tower of the newly constructed Hill Valley Courthouse that had been taken in 1885, however the portion that showed Doc had been burned away.
Behind the scenes
- Back to the Future: Continuum Conundrum revealed that Doc had accidentally traveled to 2035 in his steam time car before he finished the Jules Verne Train, and only was able to return to 1893 with the help of Marty and Jennifer's counterparts from 1986. Because Doc visited 1986 before he visited 1985 at the end of Back to the Future Part II, Doc would not have shown up with his family in this timeline.
