JENNIFER managed to get back into the ball park and into the ladies room to run some water on a paper towel. Running back out, she put the wet towel on Marty's forehead. Then, she heard a mumble from him.
"Mom." he said, "Is that you?"
"Marty." said Jennifer, "Relax. You've been out for fifteen minutes."
"I had the worse nightmare." said Marty, "I dreamt that Jennifer went crazy, and I went to Candlestick Park in San Francisco."
"We're still here." said Jennifer, "And I'm not crazy."
Marty's eyes popped wide open.
"What?" he exclaimed. He sat up and saw Jennifer. "Jennifer." he said, "Holy geez, it wasn't a dream was it."
"Marty listen." said Jennifer, "Biff's got one of the jars of poison."
"He does?" asked Marty, "Jennifer, why didn't you go after him?"
"Marty." said Jennifer, "I had to take care of you first."
"Where did he go?" asked Marty.
"I don't know." said Jennifer, "He could be anywhere now."
"It's all my fault." said Marty, "I should've listen to Doc and sleep induced you instead of turning that thing on him."
"You didn't know, Marty." said Jennifer, "How could you."
"Forget it, Jennifer." said Marty, "Load the fusion generator. We're going back."
"Back where?" said Jennifer, producing one of the remaining jars to load Mr. Fusion.
"Back to 10:04." said Marty, "We've gotta track Biff down."
They both got into the DeLorean as Marty set the time circuits for 10:04 pm. The DeLorean lifted off the ground and flew off, going up to 88 miles per hour and back in time.
The DeLorean hovered behind the scoreboard as Marty and Jennifer watched themselves confront Biff and the re-emergence of the DeLorean. Then they saw Biff beat up the other Marty and running off and getting into a tow truck. As the truck left, Marty directed the DeLorean to follow.
As they watch the truck speed down the Bayshore Freeway, Jennifer suggested "Let's land on him and cripple his truck."
"Jennifer." said Marty, "That's a tow truck, we're in a DeLorean. He'll rip through us like tinfoil."
"Then what do we do?" asked Jennifer.
Then, Marty noticed something in the back. It was the hoverboard. Landing the car up ahead, Marty and Jennifer switch seats as Marty reached back for the hoverboard. Then the car lifted off again with Jennifer driving it now. They waited until the truck caught up to trail it. As is got close, Marty got out, standing on the hoverboard, and floated it onto the truck. Hanging onto it, Marty turned back to Jennifer and gave her the thumbs up. As he did the car flew away. Slowly but surely, Marty moved closer to the front seat of the truck and carefully open the door. There, rolling next to Biff was the jar of poison. As Marty reached in, Biff caught a sight of him and drove the truck next to an upgrade.
Thinking that Marty was disposed of Biff said "What a butthead." and drove on.
Unbeknownst to him, Marty snuck up to the door and opened it again. This time he had the poison and fled. The truck followed and caught up with him. Marty looked around and discovered that he was chased into a road that wasn't a through road. Trapped, Marty saw Biff get out of the truck and started towards him.
"Alright, butthead." said Biff, "You asked for it and now you're going to..."
Then something from behind jumped Biff. It was Jennifer. She had the sleep inducer pulled from her purse and used on Biff. Nothing happened. Biff overpowered her. As he did, he spied another jar of poison in her purse.
"What the hell?" exclaimed Biff. It was another jar of poison. Jennifer tried to break free, Biff said "Oh no you don't. You're gonna stay here with me." He reached in her purse and extracted the poison.
"Let her go, you bastard." demanded Marty.
"No way." said Biff as he opened the jar and held it poised at Jennifer's mouth. "I wanna know one thing." said Biff, "Where's your brother, Calvin."
"Let her go, Biff." said Marty.
"Only if you tell me where your brother is." said Biff, "I don't have to tell you that your ladyfriend's life depends on it." Marty froze. Biff went on. "You've got to the count of three to tell me where he is." he said, "One, two, thre..."
Then two sonic booms where heard. Marty looked up.
It was the time train.
With Biff startled, Jennifer broke free and Marty charged him, grabbing the jar of poison and putting the cap on it.
Doc poked his head out of the window of the train and said "Stand back both of you."
They did and Doc hovered the train over Biff. Something came out and spewed all over him.
"That's what I call serious shit!" said Doc.
"Thanks Doc." said Marty holding a frightened Jennifer in his arms.
"Time to go home!" said Doc,
"No argument there, Doc." said Marty as he escorted Jennifer back to the DeLorean. Within minutes they were on their way back to 1985.
++++++
As Biff emerged from the stuff he was in and the smell was familiar.
"Manure." he said, "I hate manure."
Red was strolling down the street with a bottle of whisky listening to the radio. Then something resembling a train, followed by a funny looking car appeared.
++++++
In the DeLorean, Jennifer was crying.
Outside, Doc was saying from the train, "Marty, be careful. You almost hit the train."
"Sorry Doc." said Marty.
As the train descended in to the house Marty turned to Jennifer saying "It's all over, Jennifer. We're home."
He turned to see Red outside and said "Look, there's Red"
++++++
Outside, Red saw the car descend into a house and said "Crazy drunk aliens."
