- — Western Union letter deliverer and Marty
Western Union received a letter from Dr. Emmett Brown back on September 1, 1885, and were instructed to hold on to it for seventy years, and deliver it to the exact location of the future Lyon Estates at an exact time on November 12, 1955. The letter had some legendary reputation, and the employees placed bets on whether they'd meet that McFly and hoped that he'd give some light to the origins of the msyterious letter.
Much to the letter deliverer's surprise, Marty McFly was there at the same location and time, in the middle of the street in the rain to receive the letter. The deliverer stated that some of the boys back at the office placed a bet on whether Marty would actually be present, and that he (the deliverer) had lost. After Marty signed for the letter, he opened it and exclaimed when he found that Doc had written it seventy years prior. The deliverer was understandably confused, but offered Marty his help. Marty gently refused, explaining that there was only one man who could help him.
Doc's wife, Clara Brown, also used Western Union to send a letter though time. In 1893, she left a note with the Western Union office letting Marty know that Doc was missing. When the Western Union man delivered the letter to Marty during a history lesson at Hill Valley High School in 1986, he mentioned to the teacher that his supervisor had experienced the same thing in 1955.
Marty later used the same technique to deliver a letter to Doc on January 3, 1985, before Doc finished his DeLorean time machine. Marty explained that Doc would know his experiment would be a success, as he had met Marty in 1955. He wanted Doc to build a second DeLorean, identical to the original, and stated that he should keep it hidden in a place that was a secret to everyone. He further explained that he had come from 1986, but had become stranded. He wanted Doc to pick him up at the Western Union office on December 18, 1931 at 9:35 a.m., once Doc had reached 1986 in his own timeline.
