Dad and I were chatting in the living room when FRIDAY chimed on, "Boss, Harley is requesting entrance to the penthouse."

Tony looked towards the door, grinning, "Well what are you waiting for, open up for him, girl."

The doors beeped and opened, and a brown-headed teen strolled in.

He smirked, speaking with a southern drawl, "Hello, I have a meeting with the mechanic."

I turned to Tony with a confused look, but he was already on his feet, heading over to clap the young man on the back, "Good to see you again, potato boy."

Harley passed him a small package, "Brought ya something, picked it up on the road."

Tony gave it a sniff before unwrapping it and biting into a sandwich, the smell of tuna wafting through the room making me grimace.

"Anyway," Dad tossed the sandwich onto a nearby counter and ushered Harley further into the room, "there's someone important I want you to meet."

"What, did you find another science nerd," Harley gave Dad a suspicious look, "—are you trying to form some kind of cult? Just 'cuz you're Tony Stark don't make that legal."

Dad gave him a are-you-nuts look, raising a finger in the air, "First off, if I wanted to start a cult, I could and no one would stop me" his cocky tone switched to one of disgust, "Second, no, I'm not starting a cult." His tone changed again to one of pride as he pushed Harley towards me, "Third, I'd like you to meet my daughter."

Harley's eyes widened as he registered Tony's words, looking me over with surprise. I gave a shy wave as I stood up from the couch, before extending my hand, "Y/N, it's nice to meet you."

He shook my hand with a nice firm grip despite his confounded expression as he repeated, "Daughter?"

I grinned, leaning against Dad's shoulder, "Don't you see the resemblance?"

He nodded dumbly, his hand still in mine, "Yes, ma'am I do."

I wrinkled my nose, "I'm not a ma'am."

He grinned at me, "Well, now that's all I'll be calling ya. Unless you'd prefer 'little miss'."

I pulled my hand out of his, "I'd prefer Y/N."

He winked, "Sure thing." He turned to Tony, "So what's the story with little miss here?"

Dad chuckled and I glowered at his betrayal, joining them in sitting down as he explained the story.

Harley leaned back against the couch, "Wow, that's quite the situation you've gotten yourself in then."

Dad shrugged, smiling warmly at me, "You could say that."

My phone chimed and I glanced down, seeing I had a message from Rose. I waved goodbye, leaving Dad and Harley to catch-up, heading off to my room to talk to Rose.

"Merry Christmas, Rose."

"Merry Christmas, Y/N. How was your first one in New York?"

"It was good. My dad really went all out."

"I still can't believe Tony Stark is your dad." (After a few weeks of hanging out, I'd felt bad about my lying to her and had begged Tony to let me tell her. He'd acquiesced, though made me have her and her entire family sign an NDA, which I frankly thought was overkill, but they were thankfully not offended)

"Neither can I. Speaking of—the Starks Industries Holiday Gala is coming up in a few days and Mr. LastMinute has decided to tell all the employees to bring any family over the age of 12, meaning Peter and I can attend without attracting too much attention, and he also said we could ask our friends, so I know it's last minute but would you want to come?"

She squealed into the phone, "Oh my god, are you kidding? I'd love to!"

I laughed, "Awesome. I'll tell Dad to arrange a car to come pick you up, because parking would just be atrocious."

"Great! Wait… let me check with my parents to make sure I'm allowed."

After a moment of silence, she came back on the line, "So… they said yes, BUT only if I can bring Taylor with me."

Taylor was her older brother, who she often complained about. I shrugged even though she couldn't see me, "Well, if that's the price you have to pay—it's a big place I'm sure we could ditch him if he got too annoying."

"Ooo, that sounds like a good plan."

"Great, so see you on Saturday then! I'll have FRIDAY send you invites."

We chatted for a bit longer, discussing how we'd spent our Christmas, plans for the rest of the holidays, and just idle chitchat, until FRIDAY interrupted, "Y/N, your presence is required at the landing pad to welcome the Wakandans."

I said a quick goodbye to Rose, then rushed downstairs, straightening my clothes as I went. Dad, Uncle Bucky, Steve, Peter, and Harley were all lined up just inside the doors, watching as a jet landed outside. I settled into place beside Tony, his hand coming up to rest on my shoulder. I leaned towards him, whispering, "Should I bow?"

Peter, on the other side of Tony, peeked around him, stating in an obviously tone, "Yeah, he's a king."

I nodded, but Tony flicked the back of Peter's head and turned to me, "Ignore him. They don't really do that in Wakanda."

I glared at Peter who stuck his tongue out at me, earning another flick from Dad. "Behave, kids."

The jet hatch opened and out walked the trio I'd been shown in pictures and videos: King T'Challa, Princess Shuri and Okoye, their Dora Milaje. I straightened my spine, holding my breath as the glass doors whooshed open, allowing them entrance into the room.

King T'Challa led the way, smiling broadly at Uncle Bucky and Steve who stepped forwards to meet them, exchanging hugs and happy greetings. Peter and Harley ran forward, clasping the princess in a group hug, an indiscernible rumble of chatter immediately starting up between them. Okoye watched on, a small smile on her face, which turned into an inquisitive frown when she noticed me.

The king looked over my uncle, "It's good to see you again, my friend."

Dad also stepped over to join them, the king clasping his arm in greeting. "I am glad you two have mended your rift."

Uncle Bucky shrugged, "Well, that's what becoming family will do to you, especially when a certain stubborn girl is involved."

Dad gave Uncle Bucky a mocking stern look, "I never agreed to recognizing you as family."

My uncle smirked at him, "Doesn't matter and you know it," earning a grumbled response from Dad.

The king raised his eyebrows, gesturing between them, "You two—you are family now?"

Uncle Bucky nodded. King T'Challa continued, "And who is this girl that brought this about?"

Tony and Uncle Bucky shared a proud look, moving apart so that the king could see me. I swallowed and moved over to join them, smiling shyly at him, "That would be me."

Tony placed a hand on my one shoulder, "T'Challa, this is my daughter, Y/N Y/l/n."

Before the king could respond, Uncle Bucky placed his hand on my other shoulder, "And she's also my great-niece."

King T'Challa nodded, his eyes wide, "It seems we have much to catch up on."

He extended a hand to me, "It's lovely to meet you, Y/N, anyone who could get these two to cooperate must be quite something."

I blushed, shaking his hand, "Thank you, King T'Challa, it's an honour to meet you."

"Just T'Challa, please, and this is Shuri," he summoned his sister over, explaining who I was.

She looked me over, "You're the one Peter's told me about, it's great to finally meet you. Finally, someone who can give me a break from the boys."

I grinned at her, "I know exactly what you mean."

It quickly became clear that Peter, Shuri, and Harley were close friends, and while I worried about feeling like an outsider, they happily adopted me into their group. We spent several hours chatting after Shuri's arrival, Peter and I catching the other two up on my story and various other things that had been happening around the tower. Harley and Shuri relaying stories of their latest experiments and projects, Shuri also throwing in some embarrassing T'Challa stories. Peter and Harley also began immediately planning pranks—and I threatened swift and awful retribution if they played any on me, making them cower and promise they wouldn't do anything of the kind. Shuri told me all about Wakanda, and I tried hard to hide my awe, but failed and thankfully she only giggled kindly at me.

I shrugged, "Honestly, I'm still getting used to Tony's world, it's crazy to think that you're even more advanced."

"Yes, well I will admit, Stark does do remarkable things with all this dinosaur-age equipment."

I giggled, "Oh my god, never let him hear you say that."

"Of course not, he's one of you Americans that is so easily offended. I wouldn't want to hurt his feelings. T'Challa would be cross with me."

Awhile later, they had all somehow devolved into science talk, quickly agreeing to go spend some time in the lab. Harley turned to me, "You comin', little miss?"

I glared at the name then sighed, "Nope, I stay out of the labs. Science isn't my thing, but you all have fun."

Harley and Shuri immediately took off, but Peter gave me a second, hesitating glance. I shooed him away with a smile and a reassuring, "I have things to do anyway, go on." He hesitated a moment longer before turning and running to catch up with our friends.

I turned to the ceiling, "Hey FRIDAY, can you bring me to Wanda?"

Wanda was with Natasha in her room, both looking up with smiles as I knocked on the door.

"Hey, Y/N, what's up?" Wanda asked.

I fidgeted with my hands, "Well, that Stark Holiday Gala is coming up, and I realized I don't have anything to wear, and we're about the same size so I was wondering if you have something I could borrow?"

Wanda's brow furrowed and she shared a look with Nat before turning back to me, "I mean, probably, but where's the fun in that? You have a credit card from Tony, right?"

I nodded.

Nat and Wanda grinned, saying together, "Then it's shopping time!"

Despite my protests, twenty minutes later I found myself walking into the mall with the two Avengers at my side, both wearing wigs and disguises. We went through several stores until they finally found the dress they agreed was "perfect".

"You look beautiful." Wanda told me.

"Yep, you'll have all the guys' drooling over you." Nat chimed in.

I shot her a look.

She shrugged, "What? If they're busy drooling over you, they'll be too busy to question who your father is. It's really a matter of maintaining your anonymity."

Wanda chuckled and I sighed resignedly, turning back into the changing room. "Fine, I'll get it."

Two days later, Shuri, Peter, Harley, and I had become thick as thieves, and everyone was very done with us.

While I'd refused to actually help set up any of the pranks, I'd been happy to lure unsuspecting victims. It was my summons that got a tub of jelly dumped on Steve, distracted Clint so they could bedazzle his arrows, brought Bruce to the site of a fake bleeding-out Peter, and enabled a few other shenanigans. I, of course, always concocted legitimate reasons for my summons, perfectly acting the innocent bystander, who was oh-so-surprised whenever the prank was revealed. I was also the one who suggested that Peter and Harley should convince Loki to help them, which began a whole new era of chaos in the Tower. No one remained unscathed, except for myself, Natasha (they were too afraid to incur her wrath, no matter how much she loved them) and Pepper (no one disrespects Pepper Potts with pranks).

I think everyone was relieved when the pranking came to an end, though the shenanigans certainly continued, causing no end to the consternation and confusion among the Tower's inhabitants.

At one point, Shuri had skidded into the living room where several Avengers were gathered, as well as Peter and I, causing us both to immediately sit up and point at her feet, exclaiming, "WhAt are ThoSE?!"

She lifted her feet to show off the shoes she'd donned, "They are my crocs." Then ran away again.

When the four of us found Steve and Uncle Bucky sharing a couch, but sitting at opposite ends, we all looked at each before Harley and Peter began, "Two bros, chilling in a hot tub—"

The two super soldiers looked confused, Uncle Bucky sighing as realization dawned just as Shuri and I shrieked out, "Five feet apart cuz they're not gay!"

Peter decided to try and propel himself down the building using a line of tied up sheets (webshooters on his wrists just in case), Sam stuck his head out a window yelling, "Peter, NO!"

Peter just grinned, screaming back, "Peter, YES!" and pushed himself off the wall with his feet. He accidentally used too much force, yanking down the sheets, causing the coffee table to which they were tied to, to flip out the window and fall past him. Peter stared at it wide-eyed as it went by, before letting go of the sheet with one hand to web himself up to the open window, pulling the sheets and table up with him, landing sheepishly on the floor in a pile of linen.

I was eating cereal in the kitchen while Pepper made her own breakfast. Dad sat across from me, nursing a cup of coffee. Harley and Peter, who were sharing a bedroom like the Stark not-sons they were, came stumbling into the room. Harley looked a bit more awake than Peter, but not much. At least, until Pepper turned to them, asking, "Good morning, you two. Would you like some avocado?"

Both boys immediately perked up, "FR E SH A VOCA DO!"

Tony turned to her with a tired expression, "Really, Pep? Look what you've done."

Pepper shrugged apologetically, turning back to the counter with a tiny grin.

In the middle of watching 'How the Grinch Stole Christmas' with the Avengers, Harley sat straight up, a look of urgency as he looked at Shuri, Peter, MJ, Ned, and myself who were all bundled in the blankets beside him, "WE FORGOT TO SAY MERRY CRISIS—SO MERRY CRISIS!"

MJ just rolled her eyes, but Peter's eyes turned into wide saucers, as he equally panicked sounding, blurted, "AND A HAPPY CHRITHMAS TO YOU!'

Ned was next, "ITS CHRISMAN," followed by Shuri, "MERRY CHRYSLER."

I just shook my head in fake disappointment, "Aw fuck, I can't believe you've done this…"

Of course, every single person in the room (except Steve) immediately chimed, "Language!"

Steve just dropped his head in his hands, sighing.

Nat and Steve were coming from a training session, arguing over who had really won, and Tony looked over at Nat with a grin, immediately taking her side, "So, how'd you take down Captain America?"

Cue from different places of the room (Harley was watching tv from the couch, Shuri was looking out a window, I'd been just about to exit into the kitchen, and Peter was hanging from the ceiling), an in-unison cry in fake Russian accents, "We shot heem in ze legs because his shield iz the size of a dinner plate and he iz an idiot."

Steve looked offended, Dad confused, and Nat just turned and walked away, leaving us four cackling.

Clint offered to get us all out of the tower for a bit to try and save everyone's sanity, but we passed a construction sign and the moment he saw the shared look between the 'Pyschotic Foursome' (as he'd dubbed us), he held up his hand in a stop motion, "No, don't you dar—"

Peter and I cut him off, chiming in unison, "Road work ahead?" Followed by Shuri and Harley screaming, "UH, I SURE HOPE IT DOES" so loudly that Clint jerked the wheel in surprise almost sending us into the ditch. Peter quickly quipping, "What the fuck, Richard!" made Clint glare and turn the car around heading right back to the tower, grumbling "Teenagers" over our laughter in the backseat.

The Avengers finally had enough, sending Pepper and Natasha to have a talk with us. We couldn't say no to those two, and everyone breathed a sigh of relief as peace settled once more over the tower—well, as much as it ever did.
