Bill strolled to Ford. He was collapsed on the ground and moving even the slightest bit brought him pain. The demon stared at him regretfully. He kneeled at his side and gently placed a hand on his head. Dipper could see the broken bones fix themselves beneath Ford's skin and it was as mesmerising as it was, frankly, disgusting. Dipper turned his attention to his sister when she tried standing on her own but struggled. He was quick to rush to her side and slip her arm around his neck to offer support. Exhaustion was evident in her eyes. None of them had slept in a long time but that would finally change.

"There you go…" Bill said as he helped Ford get onto his feet.

If anything, Dipper was expecting his great uncle to pull the demon into the tightest of embraces if not kiss him, but he did neither. Ford shoved Bill away wearily and stumbled back towards his family wearing a look of apprehension. The harsh action surprised all of them and left the blond with a confused expression bordering on hurt.

"Grunkle Ford…" Dipper started.

"He's a demon." Ford said with a shaking voice, "You heard him, he's at full power again. You know what that means—"

Dipper wanted to defend Bill but Ford's train of thought suddenly made sense. The only thing that had been stopping Bill from restarting his apocalypse in the time he had spent with them had been because he lacked power to do so. Now he was back to his original state as a being of pure energy and possessed a human-like body. What would guarantee them that Bill wasn't about to finish what he had started?

"I get you're worried," Bill said and he smiled a strangely soft smile, like he wasn't angry or upset at having been pushed away, "but there's a little deal that's prohibiting me from doing what I had once wanted to do. Isn't that right, Pine Tree?"

Everyone glanced at him curiously. "Oh…the promise…" Mabel muttered tiredly.

"What is he talking about?" Ford asked.

"I made a deal with him." Dipper said, "I didn't think it was legitimate because he was mortal at the time…basically, he's not allowed to hurt you."

"In return for helping with my courting efforts," Bill specified and strolled closer, "I swore never to hurt you in any way, shape, or form. Finishing my apocalypse obviously falls within that category so it's beyond my boundaries."

"And what happens after I die?" Ford frowned, "Is that your loop hole? After I die you get to finish what you started."

"It would have been, if you weren't technically immortal." Bill stated and he explained upon relishing their confused expressions, "Dimension hopping has a side effect of stunting the body's aging process. Did you not notice you haven't aged the slightest bit in the past four years?"

"What do you mean 'technically immortal'?" Dipper asked.

"Sixer here is never going to die of old age because he can't age." Bill explained, "He can die from an illness but that's nothing that can't be fixed with a little magic. The only way he can die is if he were killed."

"And it can't be by you because of our deal." Dipper nodded.

"Bingo." Bill grinned, "Not that I would want to. Ever." and he turned to look at Ford, "Because I love you too."

Ford took in a sharp breath and went stiff. At this point Dipper didn't understand why his uncle wasn't pulling the demon into a strong embrace. Hadn't he learned his lesson about needlessly holding onto the past and spoiling the present?

"You…" Ford started quietly, "You promise?"

Bill smiled gently and nodded, "As long as you promise to stay with me forever." He said.

And finally, Ford pulled the demon into his arms. He held him tightly and buried his face in his hair while Bill pressed his forehead into the other's shoulder. It was sweet and Dipper was glad the drama regarding his uncle and Bill's feelings had finally been resolved. This would be good for Ford.

Once the two finally pulled away, Bill strolled closer with his eyes on Mabel. A proud smile spread on his face and he ruffled her hair playfully. "Good job, Shooting Star!" He beamed in reference to her magic wielding, "I knew you could do it!"

Mabel blushed bashfully and turned her gaze to the ground. "We're glad you're back, Bill."

"Hey, Bill?" Stan asked.

"Yeah?"

"Why are you naked?"

Bill gestured Tad with his chin, "It was more convenient for his dumb ritual." He said and continued with a miffed tone. "He didn't even just take my clothes off, you know? He just cut them. They're totally ruined."

"So are you going to explain to us how you're back?" Dipper asked.

"Sure." He shrugged, "It's really simple, actually. I died, I went to Hell, I was tortured for two hundred years, and I came back."

"You died, like, yesterday." Dipper stated with a confused expression.

"Time works differently in Hell." Bill supplied.

"And how exactly are you a demon again?" Dipper asked.

"Kid, demons are tortured souls." He explained, "They're the ones that were tortured to the point of losing their humanity. I was tortured for two hundred years, I lost my humanity, and I regained my power as a demon."

"That's…terrible." Mabel said.

"Yeah," Bill sighed and glanced at Ford, smiling lightly, "the only thing that kept me going was the thought of seeing you again…"

Ford took his hand in his and held it firmly. He had officially moved past all the thoughts that had kept him back. He wasn't angry with Bill anymore, he might not have forgiven him but he had moved past what had once been and what could have been.

"We should go tell that government group we dealt with Tad." Stan sighed, "This whole place is a mess…it's going to take years to rebuild."

"And so many people died." Dipper added, "What are the odds everyone just decides to move away and abandon this place?"

"Fairly high, I suspect." Ford agreed.

"Not so fast!" Bill exclaimed and winked, "You've got an all-powerful demon at your disposal!"

"What? Can you really fix all of this?" Dipper asked in disbelief.

"First of all, how dare you doubt me," The demon said, clearly offended, "Secondly, yes, I can. It'll barely make a dent in my magic reservoir too."

Bill raised his hand and with a snap of his fingers, everything was back to normal. The nearby buildings were whole and no one would have guessed a power tripping Warlock had nearly destroyed everything. The burnt and burning bodies that had been lying everywhere were no longer disfigured by the fire. The people that had died woke up, holding their heads and wearing confused expressions. Tad's body had also disappeared but Dipper didn't care where it had gone. Everything was completely fixed and Bill seemed rather proud of himself.

"Voilà!" he affirmed, "None of them remember anything either. I think it's better that way. I like that this world is mostly ours alone."

"And people won't want to move out for fear of their lives." Stan said, then he paused before adding, "I'm not sure that's a good thing."

"Eh, too late now." Bill shrugged.

"Let's get back to the Mystery Shack." Ford suggested, "We'll spare the people of Gravity Falls the sight of Bill naked and send the refugees home."

They walked to Ford's car; the one that had stayed by Tad's house. It was faster than walking all the way to Stan's vehicle which had been left by the bridge. They piled into the automobile with Bill sitting at the front by Ford's side and it was better that way because the twins really didn't want to be stuck sitting next to the naked man. The drive back to the Shack revealed that Gravity Falls had officially gone back to normal. People were wandering around with bewilderment etched on their faces but they were all alive and well and that was all that mattered. The military unit that had been sent was more so confused than everyone else. Agent Powers scratched his head as he tried to remember why they had come to Gravity Falls with a small army. He would surely shrug it off and leave shortly but the Pines didn't stick around to see.

The people they kept at the Shack had ventured outside. They all looked like they wanted to go home but hesitated to for some reason. When they left the car, Dipper learned none of them understood why they were at the Mystery Shack when it was practically midnight nor how they had gotten there to begin with. Bill's magic had reached them as well regardless of the barrier Ford had set in place to keep everyone safe. Nevertheless, Stan wasted no time in shooing everyone away. Only when everyone left did Bill finally leave the car but rather than walk into the building, he stood outside and watched them patiently.

"What are you doing?" Stan asked, "Aren't you cold?"

"I would like to go inside." Bill said, "But I can't."

They stared at him quizzically until they remembered the new ward. "Oh, sorry." Ford said. He raised his hand which combusted briefly thus deactivating the protective magic.

"You're stronger than Tad," Dipper remarked, "Why didn't you just break through?"

"Because that would have been rude." Bill said, turning his nose up as he walked past Dipper.

Dipper rolled his eyes and followed him in. The demon's first stop was to go to his room and put on a pair of clothes. He pranced out shortly wearing black pants and a yellow sweater. They then all went to the living room to talk. Everything was still ruined from when Tad had set everything ablaze. A lot of work would have to go into fixing the place up. Renovations had been in order for a while now, Stan had just been too cheap to actually do them. He always pushed it back but now it was slightly impossible. Bill grinned when he saw his message on the wall.

"I told you." He sang and smiled at Ford.

"I know, I'm sorry." Ford said.

"Ugh, don't start acting like a beaten puppy." Bill whined, "You made a mistake, I died, whatever."

"Not whatever," Ford said, "I didn't think you were to come back…I…I…"

"And I forgive you." Bill said, "Stop clinging to the past otherwise we'll have a repeat of what just happened."

"I kind of doubt that." Stan mumbled and he wanted to sit on the sofa chair but he knew it would crumbled to ashes if he did.

Bill seemed to understand his predicament. He rolled his eyes and snapped his fingers again. The Shack was suddenly as it was before Tad had gone and destroyed everything. "You're welcome." He snarked.

"You know how I said I didn't support this," Stan said and gestured between Ford and Bill as he sat down, "Well, I take it back. The demon's useful."

"Thanks for your blessing." Ford said sarcastically.

"So what now?" Dipper asked.

"That's a good question." Ford conceded.

"I know." Mabel said tiredly, "Let's go to sleep for a whole year."

"Already on it." Stan said and he got comfortable before closing his eyes.

"I suppose we can discuss what comes next some other time." Ford agreed and he took Bill's hand to lead him away.

"Don't have noisy sex again." Stan warned as they left.

"Stanley!" Ford chastised, flustered.

Dipper rolled his eyes and helped Mabel back to their room in the attic. He suddenly felt very tired and exhausted now that he knew he was safe and he knew he could rest. Neither twin bothered to change into their pyjamas. Their current clothes were comfortable enough. Mabel crawled onto her bed and Dipper trudged to his own.

"Hey, Mabel?" Dipper asked tiredly.

"Yeah?" She mumbled.

"Do you still want to leave Gravity Falls?"

But she had already fallen asleep. Dipper dozed off not long after.
