Doc brought the siblings back to his shop, letting the two of them get cleaned up. Doc gave Marty a real Western outfit so he wouldn't have to wear that clown outfit anymore. Ally walked over to Doc and pulled the picture out of her vest pocket and gave it to him.
"Doc, this is the reason why we came," she said. Doc grabbed a magnifying glass and took a closer look at the photograph. "Shot in the back by Buford Tannen, over a matter of eighty dollars?! September 7! That's this Monday! Now, I wish I paid him off!" he read aloud.
He looks at it again and asked, "Who is this Clara? I don't know anyone named Clara!" He turned towards the siblings as he asked this. "We don't know, Doc. We figured she was your girlfriend," Marty said, adjusting his shirt.
"Or maybe a close friend? That's a possibility too," Ally said, shooting her brother a look. Marty grinned at her. She was too much like him.
"She does have a point, Marty. The possibility of me falling in love is preposterous. My involvement in such a social relationship, here in 1885, resulting in a disruption of the space-time continuum. As a scientist, I can never take that risk, certainly not after we've already been through," Doc explained.
"Well, Doc, there's nothing wrong with having a girlfriend," Ally smiled. Doc was about to respond but there was another voice coming from outside. "Emmett! Emmett, are you in?" they said. Doc went over to the door and said to the siblings, "It's Hubert, the mayor,"
Doc opened the door and the mayor walked in, "Excuse me, Emmett. Do you remember last week at the town meeting when you volunteered to meet the new school teacher at the station after she came in?"
Doc nodded and replied, "Oh, yes, quite so," "Well, we just got word that she's coming in tomorrow. Here are all the details for you, and thanks for your help," the Mayor said, giving Doc a sheet of paper.
Doc thanked the Mayor and shut the door before walking back over to the siblings. Just before the Mayor left, he turned back to Doc and said, "Oh, her name is Clayton. Clara Clayton,"
Doc then shuts the door and walks over back to Marty and Ally. "Well, Doc, we know who Clara is now," Marty said. "Yeah, she's much closer than we thought," Ally added.
Doc rolls his eyes and says, "It's impossible you two. The idea of falling in love at first sight? It's romantic nonsense. There's no scientific rationale to that," Marty smiled and responded, "C'mon, Doc, it's not science. You meet the right girl, it just hits you; it's like lightning,"
"Marty, that's what happened with you and Jennifer, right? I remember how you two couldn't keep your eyes off of each other," Ally said. Marty nodded at what she said, "Yeah, since when have you seen this?"
"Aw, c'mon, Marty. I hang with you two a majority of my day. I've seen things between you two," Ally chuckled. "You're a little spy," Marty joked, giving her a shove. "Hey, how can I be a spy if I'm with you?" Ally joked back.
Marty gave her a smile and suddenly remembered how Jennifer is still in 1985, or they believed to be the alternate 1985. "God, Doc, I hope Jennifer's alright. I can't believe we just left there on the porch," Marty exclaimed.
"Yeah, did she change with the rest of the timeline?" Ally added. "Don't worry, you two. She's gonna be fine. When you both burned the almanac, the normal timeline was restored. This means once we're back in 1985, you two just gotta go to her house and wake her up," Doc assured, fixing something on that machine.
The machine suddenly started to make a loud noise and Doc climbed down the ladder. "Oh, Marty, turn that valve over there to the right," Doc directs. He does so. "There you go. Turn it all the way around," Doc instructed.
The machine rattles for a while. "Ally, grab that plate and put it under this hose," Doc instructed. Ally does what she's asked. They watched as a piece of ice falls out of the device and into the plate.
Doc picks it up with a pair of tongs and puts it in a beaker that he's using as a glass for tea. "Iced Tea?" he offered, rattling it. "Uh, no thanks, Doc," Marty declined. "I'll take some, Doc," Ally said.
Doc gives Ally the cup and she takes a swig. Both Marty and Ally look at the machine incredulously. "It's a refrigerator," Marty said.
Ally took another sip of the tea before setting down on the table. "That's pretty good," she said, wiping her mouth with her hand, "Um, Doc, do we have to get the Delorean before it's found?"
"Ah, right you are, Ally. As for Miss Clayton, she needs to find other transportation. If I never meet this woman, there's no possibility of a romantic infatuation, right?" Doc responded, perking up.
"You're the doc, Doc," Marty said, scratching the back of his neck. "Alright, then. Let's get the Delorean and get ourselves back to the future," Doc said, putting his hat on his head. He walked to another machine that was next to a mirror.
"Um, Doc. There's a problem with that. We, uh, tore a hole in the fuel tank," Ally said. Doc froze and he asks with fear in his voice, "You mean, we're out of gas?"
"Uh, yeah. No big deal, we got Mr. Fusion, right?" Marty said, still unaware of how serious the situation was. Doc turned to the siblings with wide but serious eyes, "Mr. Fusion powers the time circuits and the flux capacitor. But the internal combustion engine runs on ordinary gasoline; it always has. There's not going to be a gas station around here until sometime in the next century. Without gasoline, we can't get the Delorean up to 88 mph..."
The faces on Marty and Ally dropped, both understanding what's happening. "So what do we do?" Marty asked softly. "How do we get it back over here?" Ally added.
Outside of Hill Valley, Marty and Doc are sitting on the roof of the Delorean, which was being pulled by four horses. Ally, however, was riding on a horse right next to the Delorean.
Marty checked the speed-o-meter of the Delorean and shouted, "24!" Doc shook his head and said, "It's no use, Marty. Even the fastest horse in the world can only run 40 mph," "What do we do, Doc?" Ally called, looking at him.
"We'll figure it out when we get back to the shop!" Doc shouted over the pounding hooves of the horses. And with that, they made their way to the shop.
