Chapter Text
1.
The communal kitchen of Avengers Tower was, on most Friday nights, a chaotic symphony of domesticity and post-mission recovery. Steve Rogers was meticulously flipping blueberry pancakes—a "breakfast for dinner" tradition—while Natasha Romanoff sat at the island, sharpening a combat knife with a rhythmic shink-shink-shink that drove Clint Barton crazy.
Thor was currently regaling a disinterested Bruce Banner with tales of a Bilgesnipe hunt, while Tony Stark hovered near the espresso machine, looking like he hadn’t slept since the previous Tuesday.
The elevator doors hissed open, and the atmosphere shifted instantly. Peter Parker didn't just walk in; he vibrated in. His backpack was hanging off one shoulder, his hair was a mess of curls and static electricity, and he was clutching a tablet to his chest like it contained the secrets of the cosmos.
"Guys! Guys, you will not believe it," Peter burst out, tripping over the rug but righting himself with spider-reflexes. "I met him. I actually met him. The exchange student from Japan? He’s... Tony, he’s insane."
Tony didn’t look up from his caffeine extraction. "Easy, Underoos. Take a breath. Did you meet a cute girl? A cute boy? Did you finally find someone who understands your niche Star Wars references?"
"No! Well, yes, maybe, but that’s not the point!" Peter scrambled to the kitchen island, shoving his tablet in front of Bruce. "His name is Senku Ishigami. He’s part of the new STEM exchange program at Midtown. Bruce, look at this. Look at the notes he took on the bus today regarding the chemical composition of the city's smog. He did the math in his head. In his head, Bruce!"
Bruce pushed his glasses up his nose, squinting at the screen. Slowly, his eyebrows began to climb toward his hairline. "This... this is a derivation of the Navier-Stokes equations applied to localized atmospheric pollutants. He did this on a bus?"
"Without a calculator!" Peter gushed, his eyes wide. "He says calculators are for 'big-headed oafs' who don't understand the 'rules of the world.' He’s so cool. He’s got this hair—it looks like a leek, honestly—and he wears a lab coat over his school uniform. He calls everything 'ten billion percent' certain or 'one millimeter' off. He’s brilliant. He’s smarter than me. He might even be smarter than—"
Peter stopped, glancing guiltily at Tony.
Tony finally turned around, an amused smirk playing on his lips. "Finish that sentence, kid, and I’m cutting your web-fluid budget. Smarter than me? The guy who built a cold fusion reactor in a cave with a box of scraps?"
"Tony, look at the margin notes," Bruce interrupted, his voice hushed. "He’s not just calculating. He’s... he’s theorizing a way to reverse-engineer synthetic antibiotics using nothing but calcium carbonate and acetic acid. It’s primitive, but the logic is flawless. It’s like he’s looking at the world from the ground up."
The Shadow in the Corner
In the shadowed corner of the room, reclining on a velvet chaise lounge that definitely hadn't been there ten minutes ago, sat Loki.
The God of Mischief had been unusually quiet lately, opting to spend his "house arrest" observing the mortals with a mixture of disdain and boredom. He held a leather-bound book in one hand, but his emerald eyes were fixed on Peter.
"A mortal who scorns the tools of his age," Loki remarked, his voice a smooth, dangerous silk. "How quaint. Usually, your kind is desperate to cling to their flashing lights and metal toys. Who is this child who walks through the world with such... arrogance?"
"It's not arrogance, Loki," Peter defended, though he still looked slightly intimidated by the Prince of Lies. "It's just... facts to him. MJ actually likes him because he’s just as cynical as she is. Ned thinks he’s a wizard. But he’s just a scientist. He told me today that there is nothing 'magical' about the world, only things science hasn't explained yet."
Loki’s interest piqued, a slow, predatory smirk curling the corners of his mouth. "Nothing magical? Truly? I should like to see him explain me with his little formulas."
"He’d probably just try to take a blood sample to see if your DNA follows a different base-pair structure," Clint chimed in, tossing a grape into the air and catching it in his mouth.
The Avengers' Curiosity
The room fell into a contemplative silence. For the Avengers, Peter was the benchmark for "young genius." To hear him speak of someone with such reverence—someone his own age—was rare.
"He sounds like a handful," Steve said, placing a stack of pancakes on the table. "Is he coming over? You know the rules, Peter. Friends are welcome, but they have to clear the security protocol. We can't have just anyone wandering into the Tower."
"That's the thing!" Peter laughed, rubbing the back of his neck. "I invited him. I told him I had an internship here and that I could show him the private labs. You know what he said? He looked me dead in the eye and said, 'Unless you have a high-output furnace and a supply of pure tungsten, I'm not interested in your billionaire’s playground.'"
Tony barked out a laugh, genuinely delighted. "I like him. He’s got spunk. Bring him. Tell him I have the tungsten and a particle accelerator that’ll make his hair stand up even straighter."
"He’s coming Monday," Peter said, beaming. "Just... be normal? Please? Don't be 'The Earth’s Mightiest Heroes.' Just be... people?"
Natasha leaned forward, her green eyes glinting with mischief. "We’ll be on our best behavior, Peter. Promise."
Loki, however, said nothing. He simply closed his book and vanished in a shimmer of green light, leaving only the faint scent of ozone and cold winter air behind.
Observations from the God of Mischief
Loki reappeared in his private chambers, the high-vaulted ceilings of his rooms reflecting his dark mood. He paced the floor, the image of the boy’s notes—seen through a subtle glamour over Peter’s shoulder—burned into his mind.
He had seen many "geniuses" in his thousands of years. Usually, they were power-hungry or blinded by their own ego. But this boy, this Senku, sounded different. He sounded like someone who looked at the universe and saw a puzzle to be solved, rather than a kingdom to be ruled.
There was a certain... beauty in that kind of singular focus.
"Ten billion percent, Hmm?" Loki whispered to the empty room, the words feeling strange on his tongue.
He found himself looking at the clock. Monday was a long time away for a god who was used to getting what he wanted instantly. He felt a strange, nagging pull in his chest—a curiosity that felt uncomfortably like anticipation.
He would be there on Monday. He would see this "beautiful" young mortal who claimed magic was merely unexplained science. And then, Loki decided with a flick of his wrist that sent a green spark dancing across his knuckles, he would see exactly how long that logic held up when faced with a god.
Or, perhaps more accurately, how long Loki’s own logic would hold up when faced with him.
