His 1985 version notes that the DeLorean has been hidden in the Delgado gold mine, with instructions for replacement parts for the 1955 Doc to help repair the time machine. Doc questions how Marty would know this, when Marty reveals the 70-year-old Western Union letter he received. Marty then explains that afterwards, the 1985 Doc was in the DeLorean when it got struck by lightning, which sent him back to 1885.

Marty explains that he came back to 1955 in regards to recovering the sports almanac from Biff to save the future. This turns out to be a reality, when Marty appears, scaring Doc, whose flailing hands play ominous chords on his organ. Doc gets out his recorder and notes that he may have seen a vision of Marty afterwards saying he had 'come back from the future,' but thinks he may have been hallucinating. Marty is dozing in a chair nearby, resting his feet on his hoverboard.

Doc is shocked, saying that he just sent Marty back to the future. Marty runs to him and grabs him from behind. 1955 Doc (Christopher Lloyd) has just finished helping Marty's counterpart return to 1985, and is running down the street shouting and laughing victoriously. The synopsis below may give away important plot points. Doc and Marty's ancestor tries to convince him he's making a mistake. Marty initially declines but when Tannen calls him a coward, Marty accepts. When Tannen tries to make a move on Doc, Marty stops him that's when Tannen challenges Marty to a gunfight. That's when he has second thoughts about leaving. Doc then meets Clara Clayton, the town's new schoolteacher and is smitten with her. They think they found one which they plan to implement on the day he gets shot. So they scurry to find a way to get it up to that speed before Doc gets shot. But when Marty tells him about the gas tank, Doc tells him, without gas they can't get the Delorean up to 88 miles per hour to activate the time circuits. That's when Marty and Doc get ready to leave. Marty then shows Doc the photo of his tombstone. But along the way he meets Tannen and gets on his bad side. Upon arriving, the Delorean gets damaged and the gas tank is leaking.
