The moon slowly disappeared from the sky, the sun began to make its appearance known, and the two young men stared in awe at the new day. After the initial shock wore off, Robbie turned to Dipper, something akin to terror and awe nestled in his eyes. Meanwhile, the young demigod hovered over his sister with a concerned look on his face. The telltale signs of stress transformed his face from an innocent twelve year old to something centuries older. While Robbie felt the urge to have it out with the demon, he grudgingly admired the brunet for his loyalty towards Mabel.
"Is she all right?" Robbie asked tentatively. "I truly am…sorry—so very sorry."
The young boy looked up from his worrying over his beloved sister to smile happily at Robbie, the bright yellow hue was nearly gone. Dark brown with a tinge of impurity met Robbie's dark eyes without hesitation. If Robbie was stunned at Dipper's sudden transformation from freak of nature to a preteen, he didn't show it.
Dipper shook his head lightly. "You did what you had to do. I can't fault you for that. Besides, I was still kind of infused with Bill's essence and—" he looked bashfully away, a hand awkwardly rubbing the back of his neck. "I'm still kind of new to the endless knowledge and power surges."
The two talked for a while Mabel still slumbered in the eye of the story. The smell of ash and smoke pervaded the air, but both were confident that the forest could rebuild its former glory and level of mystery. As the rays of dawn caressed the evergreens and lit the vegetation, the young Reaper began to understand.
He was the likeliest choice to deliver the finishing blow because the supernatural creatures used the portal in Gravity Falls to infiltrate the human world. Thus, the portal and its unruly infiltrators gave Robbie special traits to withstand the demon's aura. It also didn't help that his great-great grandfather (a once famous Reaper) sired his bloodline. (Thank God it wasn't the Undertaker).
While the blood of the Reapers lay dormant in the Valentino family, they were still highly susceptible to supernatural happenings. When Robbie's parents caught wind of the demonic activity, they contacted the American Reaper Organization, but the problem was slowly transferred over to the British side of things for bureaucratic reasons. The plan was for someone to make contact with one of Bill Cipher's preferred vessel on the mortal plain. Because he wasn't a demon—more like a reality warping entity with a god complex—the Reapers had to interfere. If this was an ordinary, run of the mill nuisance, then it would have been left in the hands of the Americans.
Since the Undertaker already had a firsthand account to Bill Cipher's power, he was sent on a reconnaissance mission to investigate. If he was able to take action and exterminate the demonic entity, then more power to him. Once he saw that there were only two people who seemed viable to stop Bill Cipher, the Undertaker proceeded to interview Dipper and Robbie. Almost instantly, he knew that they were going to be perfect for their assigned roles—Robbie as a reaper and Dipper as the future demon.
Once the Undertaker collected all the information that he needed, he made sure to tell Dipper to make a deal with Bill Cipher. The deal was that Dipper would specify that he wanted Bill to have his body, but not his mind and soul. Therefore, when Bill reentered his body, Dipper's consciousness remained behind. The two spirits battled for dominance and…
"Looks like I'm partially demonic," Dipper muttered. Bitter disgust coated his tone like dried, congealed honey. Still, the boy was satisfied that things ended the way they had. "The Undertaker said that once I regained control, my body would slowly disintegrate, leaving behind massive energy. I'll be just like Bill Cipher given time."
"How long have you got left?"
"With the power that Bill had, the Undertaker gave me until the end of the summer."
"Bro…this is so cool!" Mabel waved her hands around excitedly as she surveyed her brother floating ten feet off the ground. A gaping hole fluttered with the stay wind; it was a testament of what occurred only a half hour prior. "You're like a superhero now! Definitely an improvement."
Mabel turned towards Robbie, eyed his blood stained suit, and hugged him.
"W-what?" The teenager was slightly reeling from the sudden contact, but the female was giggling with contagious mirth.
"You look great in a suit! Plus, you're totally cool and have powers just like Dipper!"
Both supernatural creatures shared a laugh before looking up at the rising sun. This was a reaction that they hadn't expected, but they were glad that had someone on their side. In the days following this incident, there was going to be so many questions, but they were both willing to take them on.
Years passed and Dipper grew into his own as his demonic powers matured and strengthened. He was no longer human or even corporeal anymore. His parents, after having realized that their son was allegedly 'dead,' held a funeral for the young boy, but his sister fervently believed that he was still alive despite her parents' best efforts to give her psychological help. After all, he trailed after her, trying his hardest to become human once more. Years passed and both twins matured and parted ways.
Mabel, like the creative woman she had become, set out to explore different parts of the world, her lust for adventure never far too behind. Meanwhile, Dipper returned to Gravity Falls to soak up the demonic energy that remained in the area.
Again, years passed and deals were made and Dipper threw away his old name in favor of a new one—Alcor. Named after one of the twin stars in the Big Dipper, his name became sacred and some people began to whisper and chant his name in the dead of night. All were hoping to curry his favor and make a deal with him.
Like his predecessor, Dipper was very shrewd and tempted his contractors with beguiling words and stunning powers.
Robbie loved his job. He grew closer to his parents and he matured into a fine, young man. Like most supernatural creatures, he could not age. In order to not attract any attention—even though most of the townspeople were complete idiots—he faked his own death and attended his own funeral.
It was a great turnout.
Like most things, they grow, evolve, mature, and finally…die.
"Did you finally say goodbye?" The Reaper rested his back against the door as he stared down his natural enemy who was hunched over the frail body under the homemade quilt.
The air was chilled and a slight breeze whistled past the open window. Even when she was an old lady, Mabel preferred to live life in a careless manner, citing that she would rather have the cold air caress her body instead of letting her young grandchildren run the AC. Truth be told, the elderly matron had already known that she was going to die in the night and something told her to keep the window open. She had muttered to herself that it was her 'twin instincts' acting up again. Her family, well-meaning and slightly concerned, chalked it up her instincts to her senility and sentimentality.
Nevertheless, her young brood responded with varying levels of hesitancy, but they complied with her last request.
The demon scoffed as he brushed brittle strands of snowy hair away from Mabel's mottled complexion.
"Of course I did…I just…"
This was a sigh that made Robbie want to look away from the mourning demon. He already knew what it was like to lose loved ones. After all, he had reaped the souls of many of the Gravity Falls townsfolk, including his parents and many of his friends. As a Reaper, he was no stranger to death. The scythe he held in his gloved hands, the scythe that the Undertaker managed to leave behind, had destroyed many memories and sent many souls back to where they belonged. Not many people fought against him, but there was some damage dealt to the gardening tool.
"You've got some time left," Robbie offered. His hand was poised over a clipboard, ready to mark down some additional notes about the current situation if need be. "I can extend the time, but I already have her stamped for collection."
"I thought you were a stickler for rules," Alcor joked. "You being a Reaper and all."
Robbie shrugged, but a pang of sadness pierced his heart.
"Hers is a great soul. She'll be up for reincarnation in a couple centuries."
"Can't wait."
"Me too."
With the go ahead from Alcor, Robbie steeled himself before placing his shovel deep into Mabel's heart.
She passed without a fuss.
Alcor left in the early rays of morning.
Robbie was left to observe Mabel's family crowd around, crying.
It was time to leave.
