As they reappeared and broke through the time barrier, Marty and the girls were relieved that they have escaped the Libyans. But the death of Emmett made Sci-Twi and the others go down in sadness. After that, they drove back to CHS and hid their time machine in the nearby bushes so no one will ever find it. Then all of a sudden they saw both Celestia and Luna as teenagers before they were principals. The girls and Marty were surprised of what they saw but they decided not to be in contact with them. So they went to the city and they saw that the city was small before it was big. Marty picked up a newspaper and it read the year 1989.
"This can't be happening. We saw Celestia and Luna as our age and this reads the year we are in." said Marty.
"Are you saying that, We are in 1989!?" asked Sunset.
"For sure yes." he said.
"Oh dear! How can we go back to our time period without making any temporal paradoxes!?" asked Sci-Twi.
"If Doc existed in 2019, then he must be here in this time period." he said.
"You mean the Emmett Brown of 1989?" asked RD.
"Well yes, if we can go to him we may have a chance to get back to our time and make less paradoxes in the space-time continuum itself." he said.
"Okay, let's find Emmett and assert his help to get us back to our time." said RD as they looked far and wide for Emmett.
As they found his house, they knocked and there was no answer. Then came is Emmett Brown of 1989. He looked at them like they are someone who he never met before.
"Well come in." he said as they went inside his house.
"Wow, he is like he never met us before." said Pinkie.
"I hope you're right." said AJ.
"Doc, you may have not met us yet but you will soon we need you to help us to get back to our time period 2019." he said.
"Yes you've built all that time traveling tech and installed them to a DMC-12 Delorean in 1985 and you've shown us that invention in 2019 like it was new and improved." Sci-Twi explained.
"Well, I have that machine in my garage since 1985, but I put it out of commission to not let it fall into the wrong hands." he said.
"You did until 30 years later you have renewed it." said AJ.
"Well take me to it." he said as they left his house and drove back to the spot where they left the car.
As they arrived they uncovered the car for Emmett to see and Twilight opened the gull-wing door to reveal the flux capacitor he invented. As he saw it he was surprised that after 30 years of decommission the time machine of 2019 is still running. As they drove back to the house and placed it in his laboratory, they have told him that it travels through time with the use of Plutonium. The doc was also reminded of that nuclear chemical.
"So Doc, do you still have any plutonium left?" asked Pinkie.
"All of it was stolen by the Libyan Nationalists and they may deliver them to build the bomb. Girls, boy, Spike, if you are to go back to your time you must get that plutonium back and stop the Libyans from building that bomb. After that use the plutonium and soon you all will be back to the future!" he said.
"Okay, well how can we find the Libyan nationalist smugglers's hideout without going out in the open getting shot?" asked Sunset.
"I have shields to protect us while we get the plutonium and bring them back here." said Rarity.
"Good thinking Rarity." said Marty.
"Okay, as we drive to find their hideout, park the Delorean to this area away from their reach, then we enter the front door as Rarity brings up the shield, Applejack you give them the horns." Sunset said as she made the plan.
"You can count on me!" she said as they drove to find the Libyan nationalist smugglers's hideout and get back the plutonium. As they found it they've parked the car at a safe distance and went to the front door to take the plutonium.
