|The Trinity|

In the hills on Echo Creek's edge, three teenaged girls walked along the steep roads that lead to the million-dollar homes that overlooked the town's suburbs and the rest of Los Angeles. All three were dressed alike, sporting the matching uniforms of their Private High School, albeit with slightly different colorations. The leading member of the procession, a blonde Caucasian with sharp eyes that bore an easily identifiable beauty mark under the left, wore a pink skirt and a dark blue jacket over her pink-collared gray shirt, and an obvious air of leadership. Right behind her was a shorter girl of Taiwanese descent, who wore a gray hoodie bearing their school's crest, and a green skirt whose color matched the barrette she wore on the left side of her hair to keep her short bangs from her eyes. The last girl, Thai in descent, was tall and slender to the point of almost being considered lanky, with messy auburn hair a few shades darker than her light brown skin and wore a purple variation of their school's uniform.

"Hey," the blonde said as she looked back at her companions. "You two ever been up here?"

Her lanky follower looked up. "Actually I haven't."

The shorter one looked up from her phone. "Me neither! But according to Maps we're almost there!"

Turning to look ahead, the blonde snorted. "It's like a whole different world, isn't it?"

The smaller girl brightened. "Like another planet, with strange denizens of unfathomable power and might!"

Tall and lanky let out a small laugh. "They're rich weirdos, not elves."

"Those are the same things when you think about it, living cloistered from the world, they're really clean, they meet in secret and mysterious ways…"

With a growl that shook through all three girls, a dark green super car, a McLaren 12c, came up the road and flew past them. The blonde and her tall friend leaped back from the curb separating them from the road in surprise as the car flew past, while their short companion tripped over her own feet in her flight, flailed, and flopped flat on her face.

"… Drive expensive cars with no disregard for human life," she finished as the tall girl all but dove to help her to her feet.

The blonde looked up the road, watching the car disappear around the curve of the winding street. She smirked as she glanced back at her accomplices.

"Whatever they need to feel like they matter, right?"

Up that very same hill the girls ascended, at the Vanderhoff residence, Trip sat by his home's in-ground pool, scowling at the unlit fire pit. He was lost in unpleasant thoughts, dwelling upon what happened during that chaotic lunch period yesterday.

It wasn't just the fight itself that had gotten to him. A magical princess from another dimension attended their school, after all, anyone could attribute that to her. It wasn't the fact that Marco, Star, and Mabel all fought those weirdos with ferocious violence and intent to kill and vice-versa. Again magical princess. It wasn't even the fact that Jackie Lynn Thomas was all but clinging to Dipper's arm while he stood on the sidelines through the entire brawl.

What had Trip agitated was all of that, and what Misao had said before all hell broke loose.

"The only reason you are not in the hospital now, broken, is because you are pathetic in every way–the beating you deserve is not worth our time."

His scowl deepened, and he turned towards his brother. Van sat at the very edge of the pool, one leg dangling in the water, his thumb brushing up his screen to scroll through Instagram. His lips were curled into a tiny smile, like he didn't have a care in the world or in his head.

It pissed him off more, to see him so blithe. "What're you so happy about, dill weed?"

"I'm waiting for someone to see us about our Pine Tree problem," Van replied. "They hit me up just this morning and they're on their way."

So he had good news and wasn't just distracted by something shiny. Trip let out a sigh and stood up from his cushioned seat near the firepit. "Well, who are they? And can they fight?"

"I don't know, but they're from St. James High School and they have a plan to make Pine Tree's life miserable for an entire weekend."

That caught Trip's attention. "SJHS? On the other side of LA? It's the middle of the morning, they should still have school."

"Yeah, but they cut it to come meet with us." Van smirked. "That's how motivated they are."

Walking over to his brother's side, Trip dropped down and sat by the pool's edge, slipping both feet into the water. "Well… if they can take Pine Tree out for longer than a weekend, then even better."

Van looked fully away from his phone. "What are you talking about?"

"I mean, we gotta get him before he gets us. Or sends any of his stupid friends to get us."

Van rolled his eyes. "Oh, now you care. You're not wrong, that's why I bumped up the reward to ten thousand dollars and asked for more than just 'messing' with them."

Trip nodded in agreement. "We gotta get Pine Tree, his sister, and all of those other losers out of here." He said before a sound broke the peaceful morning.

CLACK!

Both brothers jumped and turned towards their house. Standing right by the doors into their house, wearing Converse sneakers, blue jean overalls, a pink and green striped shirt, and a green baseball hat was Gabe. He was looking down at a pink-cased smart phone in his right hand, while he held his wooden sword in his left like a walking stick.

Trip scrambled off the couch and got up onto his feet. "What are you doing here?! Who let you in?!" He looked past Gabe and called into the house. "DeMartino! I told you not to let this guy into the house!"

"Of course, Master Trip," Dudley called back.

"Your mans ain't paid enough to keep me out," Gabe said flatly.

"Of course, Master Gabe," Dudley duly agreed.

He paid the put-upon peon no attention. "I let myself in."

Van got up and walked up to him. "Then let yourself out before I throw you out."

In an instant the tip of the wooden sword was pointed at Van. "Nah, you can fuck around right there just outside of finding out distance."

Van hesitated; he'd paid fifty bucks to see how quickly Gabe could dismantle someone with that thing.

Satisfied that the bigger Vanderhoff wasn't interested in an intimate relationship with the pool deck, Gabe pulled the sword back to rest it on his shoulder. He walked, giving the brothers a wide berth, and sat on the same poolside chair he'd made himself at home in the last time he was here.

"So what do you want?" Trip asked.

"Wanted to know if you changed your mind," Gabe replied as he brought the tip of his sword back down to the pool deck and began to lightly scratch it back and forth while he looked again at his phone.

Trip made a sour face at him. "We're still not paying you a hundred grand to beat up Pine Tree."

Van agreed. "Yeah, what are you, stupid?"

Gabe looked up at them both. "Man, I'm not the one on Instagram offering money to beat up a kid." He stopped fiddling with his sword. "You got a problem, and you want it taken care of. I have a solution, and I want to be paid for my labor. It's basic economics."

"I don't care about basic economics, you're too expensive!" Trip yelled out.

Gabe looked aside. "No shit."

Van then asked the one hundred-thousand-dollar question. "Why the heck does a Haley want a hundred grand to kick someone's ass, anyway?"

It gave Gabe pause, and the Vanderhoff brothers both felt a chill sweep across them when his gaze fell back upon them. His expression had not changed, still flat and nonchalant, but now it felt like he was glaring clear through them.

"That's none of your business," he replied in a dead calm, even as the grip on his sword gradually tightened.

Van looked at Trip, suddenly worried that the young man was going to get up and thrash the two of them. Trip returned the look, silently blaming him for whatever thrashing may come from pressing that particular button.

"Master Van. A Miss Waybright, a Miss Wu, and a Miss Boonchuy are here to speak with you," Dudley announced from the patio door, reluctantly spoiling his own fun.

All three looked to the door, and from it emerged the three young women who'd spent their morning trekking up the hills of Echo Creek to reach their destination. Sasha Waybright, the blonde, smirked when the Vanderhoff brothers turned to her. Her taller companion to her left, Anne Boonchuy was more concerned and possibly interested in the brooding young man with the sword. Her shorter companion on her right, Marcy Wu, was paying attention to anything but the people around her–starstruck from being able to set foot in such an expensive house.

Van's first impulse was to regain his composure, slide his fingers through his hair, and turn to greet the visitors with a smile. "Ladies, welcome."

Trip and Gabe unexpectedly found themselves on common ground–silently exasperated at how quickly he'd changed gears.

Sasha's smirk grew as Van walked up to her and her company. Hands in the pockets of her jacket, she nodded to him. "Sup?"

Van already liked the blonde's tone from a single word. "Hey."

Marcy, realizing people were talking, stepped forward to introduce herself. "Hello, I'm Marcy…!" Without warning she tripped over her own foot and went stumbling forward with an awkward, almost penguin-like squawk.

Anne reacted with immediate alarm. "Marcy!"

Rather than go face first into the back deck, she instead went face-first into Van's chest. "Oof."

Van caught her, absolutely thrown off his game by the girl's misstep. "Uh… you okay?"

Still face first in his pecs, Marcy gave a thumbs up. "I'm great. Also you, uh… lift."

Placing his hands on her shoulders, Van carefully pushed Marcy back and took a cautious half-step back from her in the same motion.

Marcy brushed herself off. "Ahahah… man, those floors are polished."

Sasha placed a hand atop Marcy's head, patting her. "Just stay still and look cute, Mar-Mar."

Marcy quickly snapped at attention and brought a hand up to salute. "As a button, ma'am–ow!"

She swatted herself in the forehead.

As Marcy reassured everyone with a quick "I'm okay!" Sasha took over the introductions. "As I was saying, I'm Sasha, these are my friends Marcy and Anne."

When gestured to, both girls waved. "Hey, what's up?" Anne greeted.

Sasha talked over her. "We want to make Pine Tree's whole weekend a living hell."

Gabe used his sword to hoist himself to his feet, as Van brightly responded. "All right, cool! What do you got for us?"

Sasha smirked and placed a hand on Marcy's head. "Marcy here may not look like much, but she's the best hacker on the west coast."

Marcy giggled and snorted as she humblebragged. "I wouldn't say the entire west coast. South of Bailey, sure."

Sasha hooked her other arm around Anne's neck and brought her close. "And Boonchuy, here? She has a particular set of skills that are a nightmare to people like your mark."

Van looked at Anne, the taller girl looking more out of place than Marcy at the moment. "She does?"

Anne looked at Sasha. "… I do?"

Sasha glanced back at her companion. "Trust me, babe, you do."

She pecked Anne on the cheek, causing her to break into a small blush, then turned a smoky look onto Van. "When we're done with your problem, he won't want to show his face around town ever again."

Van audibly swallowed at the exchange of affection between the two girls, and Sasha's look of intent in his direction. His face colored a little, as he tried to maintain his cool demeanor. "Nice, nice…"

Watching the unspoken part of the exchange between Shasha and Van with muted disgust, Gabe inhaled deeply, and blew it out in a long, audible sigh. Resting his wooden sword against his shoulder, he shook his head and left for the wall surrounding the Vanderhoff home without a word. Trip watched him leave with a bit of a smirk.

"Nothing to say?" He asked. "Not even gonna put out a better offer?"

Gabe shrugged his shoulders without looking back. "Y'all got this; I'm out."

As before, he scaled the wall with ease, going up and over it like it wasn't over twice his height. Sasha's eyebrows rose, while Anne and Marcy both let out a long, quiet "Whoa" at the feat. Van regarded it with disgust at how easily he impressed the girls, while Trip considered talking to his Dad about putting razor wire over top of their wall.

"Forget about him," Trip said, bringing everyone's attention away from Gabe's exit. "You say that you can put Pine Tree down. How?"

Sasha smiled again. "Don't worry your handsome face, handsome. The plan is simple, and it takes advantage of a few things I've already figured out about your problem."

She had done her homework, both Trip and Van liked that. "Like what?" The former asked.

"Like that the guy has zero presence on the internet, is apparently a paranoid conspiracy theorist, and his sister–who has neither of those problems–wildly overshares details about her life on social media." Sasha's smile took on a wicked character as she continued. "Thanks to her, I know all of Dipper Pines' weaknesses… including the one we're going to exploit."

Van shivered and muttered aside to her brother. "... Man, she's hot…"

"She's out of your league," he whispered back. "Just to be sure. You're not worried about him catching you out, what if you have to fight him?"

Anne and Marcy both looked at Sasha, silently wondering the same thing. "Relax guys. They'll never see us coming, until we're already gone, and the damage is done."

She chuckled and flipped her hair, her confident charisma capturing both young men.

"… And even in the unlikely event that we do get caught? What's the worst that he can do?"
