The trio head back to Doc's garage, which was left in disarray and in shambles. It looked as if it had been vandalized, windows are all boarded up, and it's lit up by candles. The Delorean is parked in the garage with them.

Doc opens up a book filled with old newspapers, opening it to March 16, 1973. The siblings read the front of the paper.

'GEORGE MCFLY MURDERED

Author shot dead in apparent hold up enroute to receive book award. Police baffled, search for witness'

"I went to the public library to try and make sense of all of this madness. Place was boarded up, shut down, so I broke in and borrowed some newspapers," Doc informed them. Marty shakes his head and looks over his shoulder.

"I don't get it, Doc. How can this be happening? It's like we're in hell or something!" Marty exclaimed, still sounding confused. "No, it's Hill Valley, although I cannot imagine hell being much worse than this," Doc says, raising his voice as he picks up a lit candle.

Einstein starts to whimper, getting Doc's attention. The dog was resting his head on his bed, which was turned upside down. Doc makes his way over to the poor dog. "Oh, Einie, I'm sorry, boy. This lab is an awful, awful mess!" Doc says, flipping the bed back over, patting it gently. Einstein jumps in and lays down with his head resting on the edge.

Doc runs back over to Marty and Ally. "Obviously the space-time continuum has been disrupted, creating this new temporally venced sequence resulting in this alternative reality," Doc spoke.

"English, Doc!" Marty and Ally said in sync. "Here, let me illustrate!" Doc says, picking up a chalkboard and a piece of chalk. He draws a line across it and writes the dates, 1955, 1985, and 2015 on it.

"This line represents time. Here's the present, 1985. Prior to this time, somewhere the timeline skewed off into the tangent, creating an alternate 1985," he says, pointing at the number. He writes, 'The Future and The Past,"

Doc draws the tangent line and writes "1985-A" on it. "Alternate to you, me, and Einstein. But reality to everyone else," he says as he goes into the Delorean to get something. He pulls out a familiar-looking bag.

"Recognize this?" Doc says, holding it up so the siblings could see it, "That's the bag the almanac came in. I know because the receipt is still inside it! It was in the Delorean along with this!" He holds up the top of Biff's cane, the one that was shaped like a bronze fist.

"It's the top of Biff's cane, the one from the future," Marty said in disbelief. Ally looked at her brother for a moment and said, "Then… if it's in there, then… holy hell… Biff stole the Delorean with the Almanac!"

"Precisely, Allison! He took the Delorean, went back to the past, gave it to his younger self some time in the past," Doc says, getting out a newspaper and laying it in front of the siblings.

"Look here, this is the article that shows his Biff made his first million betting on a horse," Doc says, giving them a magnifying glass to get a closer look. The almanac was sticking out of his pocket in full view for everyone to see. "He wasn't just lucky; he knew because he had all of the race results! That's how he made his entire fortune!" Doc said.

Both looked and Ally instantly perked up, "What? This son of a bitch stole our idea, Marty! He must've been listening when..." She slaps the table in anger but stopped when she realized the big screw-up they've made.

Marty had a look of guilt on his face, realizing his sister made a good point. "It's my fault… All of it is, if I hadn't bought it in the first place, none of this would've happened," There was a tear of guilt running down his face, which Ally wiped away.

"Well, that's in the past," Doc said. "Don't you mean the future, Doc?" Ally asked. Doc waves her off and says, "Whatever! It demonstrates precisely how time can be misused and why the time machine must be destroyed after we straighten all of this out,"

"Right, so can we go back to the future and stop Biff from stealing the almanac?" Marty asked him. "We can't! Because if we travel into the future from this point in time, it'll be the future of this reality!" Doc says, underlining 1985-A on the board, "In which Biff is corrupt and powerful, and married to your mother; and in which case, this has happened to me!"

Doc holds up a newspaper with him being in a straitjacket, being sent to a mental hospital. The headline said:

'EMMETT BROWN COMMITTED.

Crackpot inventor declared legally insane,'

Marty takes it, both siblings were in a state of shock and horror as Doc continued to speak, "Now, our only chance is in the past. We need to find on when, where, and how of when young Biff got his hands on the almanac,"

Marty and Ally knew what they needed to do. "We'll ask him," Marty declared. "Great to have you back, Marty. I understand that you feel bad about this but as long as we all stick together, this'll be fixed in no time," Doc said to him. "We'll make things right again," Ally added with a smile.
