This is either Reverse Pines or Depravity falls, in which Dipper and Mabel are the "bad guys" and Gideon and Pacifica are the good guys. I'm not sure which is should be considered as.
Dipper Gleeful sits solemnly at his kitchen table, hands folded neatly into his lap. Eyes sterile, never changing direction, never focusing out of view, and never blinking. His twin sister, Mabel Gleeful, has her spine-showing back turned to him as she paints a simple portrait of a single eyed triangle in a top hat and bow tie. Its one Dipper has seen multiple times, and one he wishes he had never seen.
The portrait is melancholy in black, grey, and a distinct hue of blues. Mabel has painted it several times, claiming with a neutral tone, "It's not good enough to please Bill, yet. It's still missing something." These words not filled with emotions had been repeated once for every failed portrait hanging on their walls. Dipper never asked what was missing, because every attempt looked the same to him. All 128 attempts.
Mabel speaks to dipper, but never takes her eyes off the triangle, and not once slows down her brush strokes.
"There's two new kids in town." Mabel churns the sentence into the air, awaiting a response from her twin brother.
"I know."
"Their names are Gideon and Pacifica Pines."
"I know."
"They're staying at the mystery shack with that deadbeat stan guy." she raises the pitch in her voice at the end making the sentence sound like of an offer.
A final I know is spoken from Dippers numb lips, and with that, mabel loses the little patients she ever had. At those words, she drives the paint brush down the aisle, leaving a bright blue line across the triangle man, clearly ruining the portrait attempt. She spins on her heels in what takes a fraction of a second, leaving her long brown hair bouncing behind her. She slams her hands on the table in which dipper sat, causing everything on it to jump, then land lopsided with a light thud.
"Don't you get it, Dipper?! We can start over!" She screames at a level of intensitity that would frighten even Manly Dan, and yet Dippers eyes stayed directed at the near background, focused on the blank Coffey color wall. "We can finally start over..." all intensity her tone once carried was lost in the distance of a single word. She now sounds like she did years ago, when the Gleeful twins were only 13 years old. That was the age mabel and dipper discovered the elusive book of magical items, or as they learned to call it, "Book 2"
She lifts her hands from the table and claps them together near her chest. "We can have some good-old Gleeful fun! We'll start over and use them for new spells, new magic, new amulets..." She was no longer talking to Dipper, rather to herself. "Maybe we can even trick them into finding book 1 for us!" She claps her hands once more as a sign of anticipation.
Mabel stares into her brothers eyes of nothingness, tears of joy and excitement visible in her own. She's waiting for consent. For disconsent. Anything at all is what she is waiting for. Finally, Dipper moves his eyes from viewing the wall behind mabel, and instead directs them towards Mabel herself. He did this because his pain-lit eyes said everything he couldn't.
They told Mabel, Not another soul, not another life, not another victim. I won't let you take these two for your own. Not this time. Not ever again.
Mabel seems to understand what his eye are saying, because the excitement in her own eyes is replaced with fury. She pulls back her arm, then with full force, swipes the back of her hand across Dippers face. The impact pushes Dipper out of his chair, leaving him hands and knees on the marble floor.
Mabel then closes her eyes and grabs the teal amulet hanging around her neck with a tight grasp and nimble fingers. The portrait mabel had been painting begins to hover the second her fingers touch the amulet. It soon starts to float all the way to the top of the wall where neither of the Gleefuls can reach, and then positions itself right next to the other portraits of the failed triangle man.
"It's not good enough to please Bill, yet." She says for the 129th time. "It's still missing something."
When the portrait is done adjusting itself on the wall, mabel lets go of the gem and all falls still.
"You know, Dip, you should really stop letting your eyes do the talking for you. There could be..." Then she pauses, her words falling still. the pause lingered long enough to stretch to heaven and hell and back to their room in minutes time. When she finally ends her sentence, the stinging on Dippers face had just faded.
Mabels ending word was chosen carelessly, yet cautiously.
"...consequences..." she whispers it and spits it out all at the same time if it all possible, and it seems that it had been.
What was he to say?
"I know."
