Contrary to what the cover shows, One isn't that important

Leafy was understandably angry. She couldn't believe Firey would do such a thing. If she couldn't have dream island,  no one could. She pulled out her phone... and suddenly got sacked into the gate. She saw what looked like an older Pencil and some other girl fighting. Then Firey opened the gate. "Huh? What's going on? You know what? Leafy? come right in!" She was glad she didn't have to do that.

"Wait, DID LEAFY JUST GET INTO DREAM ISLAND?

WHAT DID YOU DO!!!!!!"

Going back in time in the first place, that was an obvious mistake. Pencil knew that instantly. But wanting to see dream island seemed fine. Yet it caused the one thing that could stop everything from happening.

"Well Pencil, lookie here. The timeline will get deleted. And it wouldn't be if you weren't you."

That was the last thing she paid attention to as she just fell down.

"Moments remain. The choice is yours." "I- you couldn't possibly let this happen!" "Hey, I'm safe here! I have other ways of getting that power, with, or without your friends." Gaty thought "Oh, that won't happen. I don't know how, but I know somehow, someone will save the timeline. So put your contract away." One did so. "Keep dreaming Gaty. Well, I guess you can't..."

Then the crack kept growing until it filled the whole sky all the way around, and even the glitches were removed. Then it was over. There was no nothing left. Nothing other than a transparent background with Four, X, and Two floating around.

"I guess that's the end of BFDI. X, let's go back to the equation playground." "Okay Four..." "I'll, catch you two later." Four and X teleported away instantly. Two decided to stay in the void a bit longer.

Back in 2012, Pencil got up just to hear Golfball's voice again. "Well, in 13 years, we will cease to be." Pencil looked up and thought about it. "Wait a second, if what's stopping us from just..." "Okay Yellow face, we can spend the rest of time travelling the world" "It doesn't have to be the rest of time..." "Pencil, what are you talking about" "Guys, if time travel was what destroyed the universe, wouldn't it be reasonable to assume it can bring it back?" Pillow walked up to her. "So you mean... I can still have a world full of experiments waiting to happen?" "Exactly" Golfball rolled her eyes. "And how do you plan to do that?" "uh, by going back and stopping ourselves a few minutes ago? As long as we can hold them until Leafy steals dream island, things should go back to normal." "That- has to be the smartest thing I've ever heard you say."

"You don't have to like me Golfball, but I know where some Yoyleite and Noctiluca yoylean are. And the more we stick together, the higher chances we can do this" Donut got up "See Pencil, THAT is how you be a leader. What's the worse thing that could happen?" Winner thought about it "Well I'm not sure we can be recovered, so I guess the worst thing that could happen is we run into-"

In that moment, and intense sound was heard and thelight level lowered a lot.
