An-You can hear the song that is stuck in your platonic soulmates head. Cue Tony losing his mind because Peter's a maniac (Tony is fifteen when Peter was born, I made it different deal with it. No Spiderman)

————————

"A baby Honeybear! A baby! My platonic soulmate is a baby!" Tony shouted desperately, his shirt hanging loosely on his shoulders, baggy pyjama pants dragging on the floor as he paced.

"He won't always be a baby." Rhodey said teasingly. Tony groaned, flopping back down onto his bed.

"But he will be for the next three years. He's learning to talk Honeybear, talk! I am never going to get the ABC's out of my head." Tony groaned, punching his pillow in protest.

"You're getting what you deserve." Rhodey drawled, still propped up against his headboard reading his book.

"ABC's Rhodey! ABC's!" Tony protested.

"And imagine what your platonic soulmate has in his head. AC/DC, Metallica and Led Zeplin." Rhodey said. Tony looked up at him and narrowed his eyes.

"At least I'm introducing him to taste Rhodey," Tony muttered. Rhodey cocked his head in Tony's direction.

"How do you know they're a he?" He asked curiously. Tony looked up at him again and shrugged his shoulders.

"Dunno. Just feels right."

---------------------

"Uh, Tony, why are you crying hysterically in the bathroom?" Pepper asked. Tony looked up at her, sniffling hard and hugging one of the toilet rolls to his chest.

"My platonic soulmates a nerd." He cried. Pepper rose an eyebrow, crouching infront of Tony.

"And you know this how?" Pepper asked, gently prying the toilet roll out of Tony's hands and setting it back in the holder. Tony waved his hand, sniffling again and wiping his face.

"Star Wars theme tune is stuck in his head. It's been playing on repeat for three hours." Tony said weakly. Pepper laughed softly, helping Tony off of the floor and steadying him on his feet.

"Well, it's good to know someone shares your passion. How old is he now?" Pepper asked, steadying Tony on his feet.

"Seven and a half," Tony answered, pulling back on his jacket. Pepper nodded her head, linking arms with Tony and leading him to the living room.

"Any luck finding him yet?" She asked, Tony hummed and shook his head.

"Nope. No luck Pep."

---------------------

"Tony are you okay?" Steve asked gently. Tony promptly burst into tears, raising his hands and crying into his palms.

"Woah, okay, what's happening?" Clint asked.

"I hate twelve-year-olds!" Tony cried weakly. They all shared a confused and curious glance, then looking back at Tony who was still sobbing into his hands.

"Uh, come again?" Bruce asked weakly. Tony sniffled loudly, wiping his nose on his sleeve, not bothering to wipe away the tear tracks down his face.

"My platonic soulmate has had peel the Avacado stuck in his head for three weeks. Three weeks! And he never sleeps! I have not slept a solid eight hours in three weeks!" Tony cried, gesturing wildly in the air.

"Uh, what's that song?" Steve asked quietly. Tony sighed, scrubbing his hands over his face.

"Cue it up Jarvis, I want them to feel my pain."

--------------------------

"What're you humming over there?" Laura teased. Tony looked up in a daze, pausing his hand as he poured the coffee.

"Oh, my platonic soulmate is reciting the periodic table of elements," Tony said, a hint of a smile tugging at his lips. He was surprised Laura was awake, she was pregnant after all, Tony was just a maniac with insomnia.

"Bet that's great for you." She said in amusement. Tony snorted, nodding his head and taking a sip of his coffee.

"Oh I wish I could help him, he's gotten up to ninety nine in three days. Very proud." Tony said softly, grinning now. Laura laughed softly.

"Don't stay awake too long humming along with a thwelve-year-old."

-----------------------

"The Anxiety protocol has been activated on level twenty-three sir," FRIDAY said overhead. Tony looked up from the table at the ceiling, cocking his head.

"Who for?" Tony asked curiously.

"Peter Parker sir. Low-level internship. He got top results in the exam sent to his school." FRIDAY said, Tony nodded slowly, stroking his chin in his hand.

"Video feed please FRIDAY," Tony said quietly, ignoring the team who was watching Tony in curiosity. He winced when a hologram screen popped up, showing a boy on his hands and knees being couched through a vicious anxiety attack.

"What's Parker's deal?" Tony asked.

"Mr Parker was diagnosed with severe separation, social and general anxiety at age ten. His symptoms worsened after the death of his uncle, and he is now on several anxiety medications." FRIDAY listed. Tony nodded slowly, flicking the hologram away easily. The room was silent for several moments.

"Anxiety protocol?" Sam asked expectantly. Tony glanced up at him, still holding his chin in his hand in thought.

"Oh that, I created that after my platonic soulmate had this song stuck in his head. I didn't recognise it so I got FRIDAY to look it up for me. Apparently he wrote it but it follows a specific pattern to calm anxiety. I created the protocol for my employees when I realised thirty per cent of them have anxiety diagnosis." Tony explained simply, waving his hand.

"Why?" Wanda asked, Tony glanced at her and shrugged.

"The kid sings it in his head almost every day. Freaks me out, he's worse than me. I spent all night making the protocol, hoping that it could help someone like him." Tony said dismissively.

"Kid?" Bucky asked quietly.

"Oh, started getting songs and beats in my head when I was sixteen that matched a one-year-old. He should be around thirteen or so now." Tony said while waving a hand.

"Wow, surprised you haven't met him yet."

----------------------------

"What was that?" Bucky asked quietly after the smashing of glass was heard. The team all sighed and stood up from their seats, walking into the kitchen and stopping, Tony frozen in the middle of the kitchen, glass smashed at his feet.

"What the fuck. What the fuck. What the fuck. What the fuck." He muttered repeatedly.

"Um, what the hell is going on?" Scott asked. Tony swallowed, looking up at the team with wide eyes.

"I knew fourteen-year-olds were scary but what the fuck? I didn't listen to this shit when I was fourteen." Tony said incredulously. Scott rose an eyebrow and turned to Steve who shrugged his shoulders.

"Um. Explain? Please?" Wanda said hesitantly. Tony nodded, blinking rapidly.

"My platonic soulmate is weird. FRIDAY? Play Methhead freestyle please." Tony said. The team all stood in shock when the song started blaring out of the speakers.

"I see why you always have headaches."

--------------------------

"Who hurt you," Tony whispered, dropping his deck of UNO cards onto the coffee table, tears burning in his eyes.

"Huh? I only got a plus two, no biggie." Clint said in dismissal. Tony screed his eyes shut.

"No not that bird brain. My Platonic soulmate, he had tainted love stuck in his head." Tony said, tears threatening to spill.

"Oh. How old is he now?" Sam asked. Tony counted on his fingers for a moment.

"About fourteen," Tony said tiredly, tears spilling down his cheeks as the song switched to wrecking ball.

"Ah. First, break up." Bucky said solemnly. Tony nodded, pulling one of the cushions off the couch and hugging it to his chest.

"Why wrecking ball? Why?!" Tony cried.

If Tony spent the next few days breaking into fits of sobs and reciting lyrics, the team randomly hugging him then no one was going to say anything.

----------------------

"FRIDAY? Why does my soulmate have back in black stuck in their head?" Tony asked curiously, looking up from his blueprints with furrowed eyebrows.

"It appears your taste in music has rubbed off on him sir." FRIDAY said in amusement. Tony hummed, shaking his head.

"No, it's only three lines on repeat. Wait, when did this coffee get here?" Tony asked, staring at the coffee in confusion.

"An intern, Peter Parker brought it up several moments ago." FRIDAY said, Tony rose an eyebrow, his back straightening.

"Video clip FRI, with sound please." Tony said, staring at the hologram screen which showed Peter entering the lab with the coffees, FRIDAY telling him to put the coffees down as Tony was too absorbed in his work. The three lines playing in the lab were the ones stuck in his soulmates head.

"Baby girl? I think I just found my platonic soulmate."

---------------------------

"What're you doing up here kid? You lost?" Steve asked the boy who just stepped out of the elevator. The boy reddened dramatically, shaking his head.

"Uh no Mr Rogers, Miss FRIDAY said I had to deliver these coffees up to this level. But uh, I don't know who they're for." He said sheepishly, his bangs falling over his glasses.

"FRIDAY?" Natasha asked for confirmation.

"Mr Stark sent for coffees specially delivered by Mr Parker," FRIDAY confirmed. Peter smiled weakly in response, raising the coffees for show.

"Uh, why?" Clint asked hesitantly. Tony strolled into the room, locking eyes with Peter and taking the coffee from his hands.

"Napkins?" Tony asked expectantly. Peter was frozen for a moment before reaching into his pocket and handing Tony a wad of Napkins.

"I uh, I have to get back down to the labs. Uh, enjoy your coffees, sir." Peter said awkwardly, going to turn on his heel only for his wrist to be caugth by Tony, making him freeze. Tony winced when he noticed the tears burning in Peter's eyes, his wrist trembling in his grip and breathing erratic.

"What song have you got stuck in your head kid?" Tony asked gently, dropping Peter's wrist. Peter's eyebrows furrowed, eyes narrowing and nose scrunching up in concentration.

"Uh, Don't you forget about me by Simple minds? Um, what about you Sir?" Peter asked. Tony nodded to himself, a grin spreading across his features.

"Back in Black by AC/DC." Tony said with a wide grin. Peter's mouth fell into an 'o', his cheeks reddening and hand dropping limply to his sides.

"Oh. Hi, then I guess." Peter said awkwardly with a sheepish grin. Tony snorted.

"Hi, kiddo. How old are you? Fifteen? Fourteen?" Tony asked.

"Just turned fifteen sir." He answered. Tony rolled his eyes.

"Drop the sir and Mr Stark, we're bound together for life kiddo. Get used to it." Tony drawled. Peter nodded mutely, drumming his thighs.

"So, uh, do I go back to the labs now?" He said after a few moments. Tony rolled his eyes, linking arms with Peter and dragging him into the living room.

"No way. I'm promoting you. Sit, I've been hearing your songs in my head since I was sixteen, I have a lot of questions." Tony said. Peter nodded, allowing Tony to push him into one of the many couches, flinching when Tony dropped into the seat beside him.

"First, family?" Tony asked, Peter winced.

"Uh, I'm an orphan, and I'm living with my last living relative, my aunt May," Peter said quietly, Tony winced and nodded.

"She hot?" Tony asked. Peter snapped his head up to look at him, looking like he was ready to snap Tony's neck.

"Famous or not I will not hesitate to break your spine." He spat. Tony raised his hands in defeat.

"Sorry kid, I cover negative emotions with jokes. Sorry to hear about your parents, I hope you and your aunt are okay." Tony said soothingly. Peter nodded curtly, fisting the fabric of his jeans. Tony winced when the anxiety song started singing in his mind.

"Calm down kiddo, no need to be anxious. I'm not going to kill you." Tony said gently, the song slowly faded until there was a gently tune playing in his mind.

"What's that tune?" He asked quietly. Peter looked up at him and reddened.

"My mum wrote it. She used to play it on the piano when I was a baby." Peter said quietly. Tony nodded, not minding the song at all.

"You found your romantic soulmate yet?" He asked suddenly. Peter's cheeks reddened further, shaking his head frantically, his curls bounding around, raising his hands in defence.

"No way, I'm only fifteen. May said she didn't find my uncle Ben until she was thirty, and my parents didn't find each other until they were twenty-six. Only a few of my friends have found their romantic soulmates so far." Peter rambled nervously. Tony nodded his head.

"Where's your mark?" He asked. Peter reddened, lifting his shirt, showing the handprint on his sharp his bone.

"Embarrassing right? I never take my shirt off in the change rooms." Peter said in humiliation. Tony waved his hand, parting his hair so Peter could see the red mark, meaning he'd found his soulmate.

"Pepper hit me over the head first meeting we had together. Never been able to shave my head, not that I would look good mind you." Tony teased, Peter's grin widened.

"No, no it wouldn't," Peter said back, Tony held an offended hand to his chest.

"Excuse you, I'll have you know I am still Tony Stark." He teased. Peter rolled his eyes.

"Dude you've already seen my soul mark, not even my aunt's seen that since I was like five." Peter sorted, waving his hand in dismissal.

"Speaking of your aunt, I have to meet her. You're spending the night." Tony said, already tapping away on his phone.

"Do I get a choice in this?" Peter asked, raising an eyebrow.

"No. Plus I want to know more about that break up when you were fourteen. I didn't stop crying for three weeks."
