Alright, so...hey, everyone. Long time no see.

I won't keep you from reading what you're really here for any longer.

Disclaimer: I own nothing Marvel of Glee related. Fox and Marvel obviously do.

"You're torquing it wrong!"

"Wrong? Are you crazy? I'm torquing it to specs!"

"I customized the bolts myself! I know what I'm talking about!"

Kurt leaned back away from the engine, looked at Tony with an annoyed face, and crossed his arms. "No, way—really? Like I didn't notice—especially since you had to put your name on them. Ego much?"

Tony huffed at the teen. "If you knew they were custom, then why were you tightening them to the original specs? You're so sassy, fae!"

Kurt rolled his eyes as he waved the torque wrench at the billionaire. "Because I thought you were smart enough to at least make the right bolts for the engine."

"I'm the genius here, and I wanted custom bolts!"

Kurt waved the wrench closer to Tony, his expression basically screaming, I want to hit you with this, but my boyfriend would not be happy with me… He sighed and moved over to a workbench and grabbed different scraps of metal until he found one he liked; he moved to the cutting table. "You want custom bolts? I'll give you custom bolts that actually work."

Tony followed Kurt. "Wait, do you know what you're doing?"

Kurt ignored him and sketched out a brief design.

"What about the measure…"

Kurt grabbed a ruler and started writing numbers on the paper in front of him.

Tony raised an eyebrow as he watched Kurt finish his design and move to the cutter. "I don't know if you know how to use that, but I don't want virgin blood on my workbench like some kind of Aztec sacrificial altar."

Kurt avoided eye contact as his ears turned a lovely shade of pink, which immediately caught Tony's attention.

"Aww," Tony cooed. "You thought I didn't kno…"

Kurt put on a pair of safety glasses and turned on the machine, effectively cutting off the older man's voice.

Manipulating the metal as he worked, but not so much that Tony would notice, Kurt quickly produced a full set of custom bolts for the engine. He turned and faced Tony who looked at them skeptically. "I don't know, fae…"

Kurt just rolled his eyes and walked back to the car. He replaced the old bolts with the new ones and torqued them in the right pattern and pressure before turning to Tony and looking at him expectantly.

Tony huffed and turned on the car and let in run for five minutes before turning it off and walking back to Kurt. He crossed his arms and stared at Kurt.

Kurt merely raised an eyebrow and waited.

After a moment Tony let out a breath and nodded his head once.

When he had first seen the boy, Tony'd thought the kid was a bit too skinny for his height and looked on the effeminate side. But never judge a book by its cover. The kid was slowly impressing him. He kind of liked Kurt, but chances were he wasn't saying it out loud anytime soon.

Tony cleared his throat as they worked. "So, what does your dad do for a living?" He was trying the small talk approach.

"Hmm?" Kurt replied absently, and then, realizing a more specific response was indicated, added, "Oh, he's a mechanic. He owns a few garages in Ohio," he answered without looking up from the engine.

"Ah, that's how you know about cars." He was kind of hoping this was something Kurt had taken his own interest in.

"Well," Kurt started, still focused on the car, "Dad loves cars, but he never forced me to learn anything about them. He would've been just as proud of me if I'd stuck to my tea parties, but I ended up loving cars, too. I guess some things are just genetic." He laughed softly.

Tony nodded; Blaine liked building things just as much as he did. "Makes sense. What about your mom?"

"My mom's a nurse at Lima Community Hospital." Kurt grabbed a rag and started cleaning his hands as he turned to face Tony. "My birth mother was a stay at home mom until she passed away when I was really young."

Tony winced. Bad topic. "Look, I'm sor…"

Kurt cut him off. "Don't apologize for something that's not your fault." He put the rag in his back pocket. "It's not like you weren't going to find out from whatever background check you're probably running on me even as we speak." As Tony's eyes widened with surprise, Kurt shrugged his shoulders and let his lips twitch upward in a small smile; he continued before the man could deny the fact. "Plus, Carole's a good mom. She might not be my first mom, but she's still my mom, and I love her just the same. Without her I wouldn't have Finn, and my dad wouldn't be as happy."

"That's good." Tony nodded. "Wait, who's Finn?"

Kurt full-on grinned now. "My big brother of course. Tall, goofy guy, football quarterback, all-American. Likes to carry me on his back, doesn't have a problem telling people I'm his little brother, and would take care of anyone that decides to hurt me for being gay."

Tony nodded; he liked the kid already. "Your dad okay with you being gay?"

Kurt's grin turned into a proud smile. "Dad loves me for me. He said it's my job to be who I am and his job is to make sure I can be. Being gay doesn't make me any less of a man to him."

"I gotta meet this guy." Tony's voice held approval.

Kurt shrugged. "I don't see how you're not going to meet him while we're here. He's curious as to who Blaine's mystery parents are."

His own thoughts about Tony were still to be fully determined upon later examination. He wasn't about to hold biased judgment on the man just because of the media face he held. People hear and see what they want about celebrities—especially the drama. People love drama about celebrities.

Kurt knew the man obviously held his son close to his heart—even if only by the "overprotective father wanting to intimidate his kid's boyfriend" card he'd attempted to play on Kurt within ten minutes of their meeting. Tony was a genius by his own right. Intellectually the man was an astounding inventor and creator; his contributions in the field of science alone were incredible. To not acknowledge that—even privately, within his own mind—was implausible.

The fact that the guy had a colossal ego—one that rivaled that of Joseph Stalin—was a path Kurt didn't want to travel right now. For now he'd settle for getting to know the man better.

"Hmm," Tony murmured, nodding in thought and with a grin on his face. "So, I can get all the embarrassing details about you from him?"

"Depends." Kurt closed the hood of the car and leaned back against it. "Do I get all the embarrassing details about Blaine from you?" His own lips tugged upwards at the corners.

"It would be very cruel of me as a parent to tell you such things about my dearest son." Tony's face was a mask of sincerity. He walked to the workbench in front of the car and leaned against it, crossing his arms and facing Kurt.

The boy raised an eyebrow at the billionaire. "Really, Mr. Stark?" His voice dripped with false formality.

"I'm not one of those dads who likes to embarrass their sons." He waved his right hand in a dismissive manner. "But," Tony grinned, "I could tell you about his sixth birthday party. If it just so happens there are fond memories of certain incidents from a parent's perspective, but these memories are embarrassing from the child's perspective, well… And if it just so happens the son's boyfriend hears about these incidents, well…it's merely an accident, of course."

Kurt crossed his arms and leaned forward, giving Tony his full attention. "Really?" He smiled mischievously. "Do tell."

"Mom, Dad could be torturing him with one of his inventions!" Blaine tugged at a curl straying from his forehead. "Or worse, he could be raving about himself to Kurt!" His eyes widened comically, and he picked up his pace in looking for his boyfriend and dad. "Dear god, I have to save him!"

Pepper grabbed Blaine's hand to slow him down back to walking pace. "Maa…"

"No, Sweetie. They're probably in your dad's main lab." She pulled him down a hall. "Don't worry. Tony won't do anything too terrible, or he'll have to deal with both his wife and son being mad at him, and he can't handle both of us at once."

"Still, I shouldn't have left them alone." Blaine pointed out as though it was obvious that his dad couldn't be left alone with anyone.

"Probably." Pepper laughed as they got to the lab.

"Let's pray they aren't in some sort of vicious battle of the smarts." Blaine said before opening the doors and walking in, looking around to see where the two could be. He turned to the far end of the lab when he heard a gasp, and he and Pepper walked towards the sound.

"I…can't…breathe!" Blaine and Pepper shared a frightened look as they heard Kurt's voice struggling for air. "Shit!" they said in unison before running to the area where the cars were parked.

They saw Kurt hunched over. Tony was holding him with one arm around the waist while his other hand was hanging onto the workbench, apparently needing the solid structure to keep them both standing. Tony and Kurt were both shaking, but Kurt's gasps for air were clearly audible. "Dad!" Blaine yelled, running to them. "What'd you do to Kurt?" he asked frantically.

Kurt and Tony looked up at Blaine and Pepper before descending into another fit of laughter. Kurt tried to wipe his eyes, thankful that Tony was keeping him from collapsing.

Blaine frowned when he realized they were laughing, and Kurt wasn't dying or being maimed or something just as bad. "What's going on?" he asked as he and Pepper faced the two hysterical men.

"I can't…I…" Kurt tried to speak.

"Shh. Don't look at them!" Tony managed to tell Kurt between his own gasps for air.

Pepper stepped forward, not looking too impressed with Tony. "Tony, what did you do to the boy?"

Uh-oh. Tony knew that tone. He forced himself to stop laughing and to stand up straight, while still keeping a laughing Kurt on his feet. He put on an innocent face. "I didn't do anything. We worked on a car and talked. That's it."

Pepper crossed her arms and looked at Kurt before returning her gaze to Tony. "Are you sure about that, Sweetheart?" she said in a voice that sounded way too sweet.

Tony gulped audibly. "Y-yes, Baby."

Blaine smirked at his dad, his face clearly conveying his thoughts. You are so whipped, Dad.

Before Tony could get a word in edge-wise to respond to that look, Pepper shot him another one of her don't mess with me glares and demanded, "Explain then, why Kurt is in hysterics right now."

Realizing he was on the verge of a very unhappy conversation, Tony's eyes shifted to Kurt, and he poked him in his side. "Come on, elf ears, stand up." He tugged Kurt into a fully upright position. "Explain that I didn't do anything wrong before my wife kills me."

Kurt looked up, stifling his giggles, saw Blaine, and struggled valiantly to resist breaking into laughter again.

Blaine frowned at Kurt, wondering what his dad could have possibly done to get him to laugh like this. It couldn't be good. "Kurt," he said, unaware of how much like Pepper he sounded just then.

Shit. Kurt knew that tone. He sobered up quickly and shot a glare at Tony for getting him in trouble. "Yes, my love?" he asked innocently.

"What did my dad do to you?" Blaine asked, confusion seeping into his voice.

Kurt glanced at Tony before answering. "He messed up a perfectly good car, and I fixed it. Then we t-talked for a b-bit." His voice started to crack at the end of the sentence as he thought back to what Tony had told him.

"Kurt…" Blaine started.

"I didn't know you were afraid of capes!" Kurt blurted.

Blaine snapped his mouth shut as his eyes narrowed noticeably. He turned to face his dad with a glare. "You did not tell him."

Tony scratched the back of his neck as he tried to think of a way out his predicament. "Tell him what? We were working on the car and…"

"You told him about my sixth birthday party?" Blaine whined loudly.

"I…ah." Tony looked for an out but couldn't find one. So much for being a genius, he thought.

"Tony," Pepper pinched the bridge of her nose. "Did you just tell him, or did you tell him and show him pictures?"

Tony took a step back. "I…" He bumped into the table, accidentally turning his hologram computer on again. A 3-D image of a much younger Blaine wearing a torn red cape appeared; he was covered in chocolate ice cream from head to toe. "Shit!" he hissed as he frantically shut off his computer.

"Tony!" Pepper called sharply to get the man's attention.

Tony closed his eyes for a second before turning and facing the angry duo and a slightly confused, slightly scared Kurt. Remembering the smirk on Blaine's face, he realized he wasn't the only one—He's whipped, too. Well, misery loves company and all that crap... He faced Pepper. "Yes, Beautiful?" he asked, trying to add as much charm as possible.

Pepper clicked her tongue and shook her head. "Nuh-uh. That's not going to work this time, Tony."

Blaine leaned over to Kurt and whispered, "He's in so much trouble with my mom." Kurt just nodded, not wanting to get into any more trouble himself.

Tony looked around and spotted exactly what he needed. He cleared his throat and ran to the side of the lab where his Iron Man suits were. He suited up into his newest model and faced the three other occupants in the room.

Kurt blinked a few times. "Does he usually do this to avoid getting in trouble?" he asked both Blaine and Pepper.

Pepper nodded. "You'd be surprised how often actually." She turned and faced Kurt with a smile. "It's nice to finally meet you; Blaine talks about you all the time." She pulled Kurt into a hug. "You are a cutie."

Kurt blushed and heard Blaine's cry of "Maa," but hugged her back. "You're quite beautiful yourself, Ms. Potts," he responded, getting his confidence and composure back.

"Thank you, Sweetie." Pepper smiled at him and shot Blaine an approving look. "I like him."

Blaine grinned.

"Hey! No hitting on my wife, pointy ears!" Iron Man yelled.

"I'm gay," Kurt replied sardonically as he blinked slowly. "I'm dating your son." He pointed to Blaine.

"Yeah," Blaine voiced. "The son you embarrassed and are now hiding from inside your metal suit."

"Hey!" Tony started ranting in his defense as Kurt gained a mischievous smirk after thinking about Blaine's words. Metal suit—interesting. I should've thought of this sooner. He looked up in time to school his face into a look of neutrality as Tony started walking towards them. Perfect, Kurt grinned mentally.

"Dad, get out of the armor," Blaine insisted.

"No." Tony stepped forward and promptly fell forward onto his face—well, Iron Man's face. He stayed on the floor a moment before standing up. He took a cautious step forward and audibly sighed in relief at not falling again. He shrugged and walked forward again only to fall on his face again. "What the…?" He stood up—again.

Blaine started to bite his lip to keep from laughing. "Everything okay, Dad?"

Tony retracted his face armor and frowned down at his suit. "Yeah, just tripped, I guess."

"Tripped? Twice? Over nothing?" Amused, Blaine crossed his arms and looked at his dad, unconsciously mimicking his mom's pose.

He's a lot like his mom. Kurt turned back to watch Tony try to figure out what was wrong with his suit.

"There's never nothing, B." Tony waved his hand around. "Molecules and such." He took a few cautious steps forward and fell backwards. "That's it! Suit off!" he yelled, getting up only to frown when nothing happened.

He was still trying to figure out what was wrong with his Iron Man suit; he couldn't understand what could possibly be wrong with it that would cause him to repeatedly lose balance and fall. Pausing in his frustrated examination of his suit, he looked up, staring suspiciously at his son. "What's so funny, B?"

Blaine giggled and hid slightly behind Kurt. "Nothing."

Tony narrowed his eyes at the boy. "Then why are you giggling?"

The boy tucked himself further into his boyfriend's side and shared an amused look with his mom. "You can't figure out what's wrong with your own invention," he said quickly as Kurt grinned, putting his arm around the shorter teen's shoulders.

"Don't make me ground you, Kid," Tony warned, taking a step towards Blaine.

Blaine laughed loudly. "That won't fix your suit," he pointed out, causing Pepper and Kurt to laugh at Tony's pout.

"Not funny," Tony grumbled.

Kurt laughed, realizing he'd had enough fun and wouldn't interfere anymore. Man, Finn would think this is funny!

Tony cautiously walked around, noting that nothing was causing him to trip. "Suit off." He was slightly surprised when the suit actually came off, and he stood there confused for a moment. Then he shrugged and announced, "I want a snack. Who else wants a snack?"

Kurt and Blaine both raised a hand before turning to Pepper who rolled her eyes at the boys. "All right, come on. Let's go to the kitchen."

Both Starks grinned in unison as they replied. "Awesome!"

"So, you're Blaine's boyfriend?" Steve asked before biting into his muffin, waiting for Kurt to reply.

"That would be correct," Kurt answered, feeling everyone look at him. Weird... Natasha had been staring him as if he was some mark she needed to eliminate. …that's unsettling.

"How long have you two been together?" Bruce asked—thankfully without giving Kurt the same look Natasha and Clint were giving him.

Kurt put his muffin down so he could speak. "Six months," he replied, shooting a smile to Blaine, who returned it.

"Oh!" he said, suddenly remembering as he dug into his pocket. He pulled out a leather-corded necklace that had a platinum pendant. "I…ah…I made this for you," he said, offering it to Blaine.

"Really?" Blaine took it and studied the pendant. "It's beautiful, but what's the design on it?" he asked, securing it around his neck.

"I…um…" Kurt blushed. "Nothing special, really, just something I came up with."

Blaine smiled, looking down at his necklace before looking back up to Kurt. "Well, I love it. Thank you." He reached over and squeezed his boyfriend's hand. He tucked the pendant under his shirt and didn't notice the slight blue glow it emitted after touching his skin.

"You're welcome, B." Kurt squeezed his hand in return as they resumed eating their muffins, ignoring the adults who were watching them.

Pepper cleared her throat, effectively getting everyone to look away from the two teens. "So, what car did you guys work on, Tony?"

"Well…"

"We didn't work on it much; mostly I just yelled at him for messing up a perfectly good car before I remedied the situation," Kurt explained while Tony paused. He added a quiet "thank you" as Blaine poured juice into their glasses.

Blaine snorted and looked at his dad sadly. "Dad, don't take this too badly, but Kurt knows cars better than anyone I know." He patted his dad's shoulder. "Which car did you show him?"

"The silver bullet," Tony grumbled.

Blaine nodded in understanding. "Well, that explains it."

Tony's forehead scrunched up. "How?"

"You customized it." Blaine flatly pointed out.

"So?"

Blaine shook his head. "No, that's it. It's self-explanatory."

Tony huffed. "Whatever." He stuffed more muffin in his mouth.

Clint turned to Kurt. "You yelled at Tony because of a customized car?" His expression showed his confusion.

Kurt shrugged. "He messed up a perfectly good car, and I ended up fixing it." He shot a look at Tony. "For some reason, he wanted custom bolts that didn't work right for the engine."

Tony rolled his eyes and flapped his hand. "I really thought you were going to end up killing yourself at the cutting table. I have a 'no spilled blood in the lab' rule."

"Why did you use the cutting table, and why did Tony let you?" Bruce started feeling the need to hit Tony over the head with something hard—preferably something made of metal.

"I made him some custom bolts that actually worked." Kurt tilted his head to the side. "Oh, and he didn't really get much of a chance to stop me; he was too busy listening to himself talk while questioning my capabilities and intelligence." He knew he might be sounding arrogant, but it was the truth; besides, he knew he would get a rise out of Tony. Sure enough…

"Was not!" came Tony's muffled defense since his mouth was full of muffin. Pepper scolded him.

"Exactly how smart are you?" Bruce wondered as he tried to put together the puzzle known as Kurt Hummel. "Blaine told us you were smart, but still..."

Kurt raised an eyebrow and looked from a sheepish Blaine back to Bruce. "Really depends. Are we talking about grades, IQ, SAT scores, proficiency in certain fields of study, number of languages I speak, random knowledge? Then again, there are numerous definitions of "smart"—we can refer to book smart, people smart, and so on. I'm sorry, but you need to be more specific with your question, Dr. Banner."

Thus began Kurt's inquisition by the team. The teen answered their questions, being careful not to give away anything important or make them suspicious.

It all came to a boiling point with Kurt and Natasha arguing about the merits of different pistols and proper ways of concealing them while wearing a short, strapless dress.

Loudly.

In Russian.

"Uh, what are they even arguing about now?" Steve asked as his eyes darted back and forth between the two people debating in the middle of the living room. His eyes vaguely looked as if he was watching a pong video game.

Bruce looked somewhat frightened for Kurt, but mostly he was just confused. "I have no clue."

Pepper looked towards Blaine and gave him an expression that clearly implied, Really? "Curly," she said, "you're totally into this."

Blaine blushed. "He's hot when he's aggressive or using another language—and now he's doing both," he admitted, feeling his ears burn when he realized he'd admitted this to his mom. "Forget I said that!" he added quickly, not bothering to move his eyes from his boyfriend.

"He just looks scary to me." Steve put in.

"They both look like angry badgers." Tony piped up.

The two in question halted their argument and turned towards Tony and Steve.

*"Du Idiot!"

"Du siehst aus wie eine Ziege mit einem tan!"

"Er tut."

"Einverstanden."

"German." Steve pointed out awestruck. "They switched to German."

Tony just frowned. "I'm positive they were insulting me, though."

Kurt and Nat rolled their eyes in unison, inexplicably intimidating Steve, Bruce, and Clint.

Kurt turned to Nat and switched languages again, to Dutch this time. "Je ziet er fantastisch in leder." He nodded approvingly.

"Blauw is je kleur." Natasha pointed out as she eyed his apparel.

"Een pistool past bij jou."

"Ik vind je leuk."

Kurt raised an eyebrow. "About time you admitted it." He leaned forward and whispered into the woman's ear, "Your eyes burn fiercely when you speak your native tongue," referring to their first argument. He pulled away and stood in front of Natasha with a small smile.

A genuine smile found a home on the assassin's face, stunning the audience. "Oh, I am definitely keeping you!" she said, tossing an arm around Kurt's shoulders. They turned to the others, who were watching open-mouthed.

"Oh fuck, they're friends."

"There's two of them."

"I repeat: 'scary'."

Blaine regained his cool, stood up and grabbed Kurt's arm, tugging him away from Nat and into his arms. "Nope, mine. Find your own, Nat." She opened her mouth to speak. "Not sharing either!" he said pointedly before she could come up with a reply.

Nat reached over and ruffled Blaine's hair. "You're lucky I like you both." She threw a wink at Kurt; the teen just raised an eyebrow—pondering the underlying threat of what she would be like if she didn't like him—as the side of his mouth quirked upwards.

The look in the teen's eyes caused Natasha to blink quickly, recognizing the look as one she knew she personally wore during missions. Simply put it was I'm not the only one being tested here, and that alone was enough to make her all the more curious about the chestnut-haired boy.

"Sir, Master Kurt's family is here to see him," JARVIS interrupted.

Kurt looked down at the watch Blaine had given him earlier. "They're early." He frowned.

Tony shrugged. "The more the merrier and all that crap."

"Tony!" Pepper admonished.

Tony shrugged again. Like they don't hear worse on TV. "Let them in, JARVIS. I want to meet the Hummels."

It didn't take long before Finn was leading the charge into the living room, running to Kurt. "Kurtie!" He yelled, lifting the other teen. "We're in the Avengers' Tower! This is awesome!"

"Stark Tower," Tony corrected, but he was drowned out as Clint stood up and yelled, "Enemy mutant in the tower!"

Natasha pulled a dual set of guns—out of god knows where—while Clint suddenly had two throwing knives in his hands. Steve assumed a boxing stance, and Bruce stood up—unwilling to Hulk out unless absolutely necessary—as Tony called his suit while protectively standing in front of his wife and son.

Finn and Kurt blinked in unison and turned towards where Clint was staring; Kurt sighed and squirmed out of Finn's grip. "He's no enemy mutant." He shot Blaine an abashed, worried smile. "That's my grandfather."

Tony removed his face armor. "That..." he pointed to a bored-looking Erik, "is your grandpa?"

Kurt nodded and turned to the older mutant. "Hi, Opa." He received a smile and hug from the man.

"Hello, Grandson." Erik squeezed the teen once more before releasing him.

There was a tense silence as the team eyed Erik as though he was going to attack them at any moment. Blaine looked at Kurt questioningly. The Hummels wondered what the heck they'd walked into exactly. And Kurt—well, he was doing a good job of hiding his panic as he studied everyone's defensive tactics while conveniently avoiding Blaine's eyes.

"Hey, I don't appreciate weapons being aimed at my kid and my father!" Burt's slightly angry voice broke the silence as he eyed the Avengers; he didn't look the least bit impressed.

Pepper turned to the team. "Boys…" She paused before adding, "and Natasha."

Slowly the team lowered their weapons, while not quite relaxing their guarded stances.

"So," Agent Coulson prompted, having arrived while the stare-down was occurring. "Who wants to explain why Erik is here and why you all aimed weapons at unarmed citizens?"

"Shit. The babysitter's here," Tony grumbled before clearing his throat and speaking up. "Magneto waltzed into my house, Clint yelled about an enemy mutant, and we reacted. Apparently, though, my son's boyfriend claims Magneto is his grandfather," he said while eyeing both Magneto and Kurt. Then his eyes landed on Burt, and he blurted, "Wait, you're Kurt's dad?" He looked between the two, trying to find the resemblance before getting hit upside the head by Pepper. "Ow!"

Burt and Kurt simultaneously crossed their arms and grunted, "Huh!"

Tony nodded in understanding. "Yeah, I can see it now."

"Tony!"
