Chapter 27: All's Well that Ends Well

The trip back to the Upstate facility was relatively uneventful. Tony alternated his attention between staring longingly at May and cuddling with Natalia, who was curled up clinging tightly to her father. Steve and Bucky had made a little huddle with their three youngest in their laps and Rebecca snuggled into Bucky's side. Natasha sat next to Tony, her eyes focused on her daughter in Tony's arms. Bruce held Natasha's hand, offering her emotional support through what had to have been her worst nightmare. Clint and Laura had made a similar huddle to Steve and Bucky's, their three children clung close.

Agent May had offered to fly them back to the facility so that Clint could reassure himself of his family's wellbeing. Peter and Ned hung out in the cockpit peppering Agent May with questions, something that had Natasha wondering what had happened with the woman over the past few years that she was so much more tolerant of a couple of teenaged boys.

When they finally got back to the Upstate facility, the children were asleep or near to it. Bucky and Steve took a few seconds to situate themselves. Steve, being the taller of the two, carried George and Rebecca, while Bucky took Sarah and Joseph. Natasha claimed Lila as she knew that Tony wasn't going to hand over Natalia. She was okay with that as she had seen first hand the impact having the little girl had had on Tony. Although only a few months had passed, Tony was completely changed. Natasha idly wondered how she could have ever believed that he was a narcissist when she had first met Tony Stark. She thought about it for a second and figured that an apology now would just make things awkward.

It took them a half hour to get the children all settled into the bedrooms that the facility had for them. Peter and Ned volunteered to keep watch on them as Tony had deactivated FRIDAY. Tony declared that he would have to create a new, completely clean AI for running everything. FRIDAY had been outdated to begin with, the precursor to JARVIS. It was little surprise, in hindsight, that Jenkins had managed to hack the system. He smirked at the thought of having Natalia assist with some of the simpler code writing and then wondered if he could poach Johnson from Coulson to help with the project.

Coulson seemed ready and waiting when Tony, Clint, Natasha, Steve, Thor, and Bruce descended on him. The others sat back and just watched as the original team ripped into Coulson for allowing them to believe he was dead for so long. Natasha and Clint were particularly vocal about how the belief of his death had impacted them. It was just another example of how the children had altered things. Coulson was stunned by how expressive Natasha was when she let lose at him. Natasha had never expressed her emotions so bluntly and thoroughly before.

By the end, it had taken a full two hours for everyone to unleash their emotions before finally telling Coulson they were happy he was alive, giving him hugs, something that stunned Coulson even further as he had never known Natasha or Tony to hug people. Still, they did so now. After that, they all went to bed with the agreement that they would start working on a plan for sorting out handling different situations and the like in the morning.

Two Weeks Later

Tony and Natasha had almost talked themselves out of allowing Natalia to attend Midtown Science. It was only under the consistent reminders from the rest of the team that they relented. Clint even pointed out that Cooper and Lila would be starting elementary school at the nearby private school without any safety net in the form of Peter being present. Of course, all the children had been injected with subdermal trackers that could only be received by Tony's new AI HELEN. Agent Johnson had agreed to assist him with the work of building impenetrable cyber security so that the Iron Family protocol could be safely implemented in the future as well.

All that said, Tony felt he heart break a little as Natalia kissed him on the cheek before getting into the car Happy was driving with Peter, Ned, and Rebecca already waiting. Tony resisted laughing a little at the sight of Natalia's Iron-Man backpack. Natalia smiled and waved at him as the car pulled out of the underground garage.

Natalia smirked as Peter adjusted her buckle on the booster seat for her. She was gleeful at being able to go to school. Oh, sure, she would miss her daddy during the day, but she would get to learn from him afterwards. Besides, this way, Peter had to pay more attention to her. Peter easily shouldered his bag when they got out of the car, the plan was that he would be carrying Natalia's and his books, something that was easy enough, given his physical strength. Natalia's bag would carry mostly her notebooks for the immediate classes.

The first day was always the worst, Peter thought, as they had the dull process of homeroom, getting their full schedules and then going to classes where the teachers just droned on about the syllabus. Natalia was intensely fascinated by the whole process, and the classes that Peter and Natalia shared with Ned and Rebecca showed that Rebecca was of a similar disposition. The girls had never encountered a normal learning environment before.

By the end of the day, when both Peter and Ned were carrying nearly double the books that all the other students were because they had the girls' books too, Ned looked at Peter and smirked, "Now, I'm really glad that Hill made me wear all those weights this summer. It makes this so much easier."

"I'm just glad that Tony made us bags that are tough enough to withstand the weight," Peter shrugged in response.

They all settled into the room that the decathlon team met. Flash, the school bully, arrived a few minutes later and laughed when he saw that Peter and Ned were sitting with little girls, "You get a new girlfriend, Penis Parker? A little young for you, isn't she?"

"Oh, I guess you didn't hear over the past few months. I can't be surprised because you never did pay attention in class. This is Natalia Stark, you know, Tony Stark's daughter. That girl next to Ned is Rebecca Barnes, the daughter of Captain America and Bucky Barnes. Ned and I got internships with Stark industries this past summer, plus my Aunt is currently heading up Tony's new ECHO program… and dating Tony Stark. It's less like she's my girlfriend and more like my super genius little cousin. Nice to see you too, Flash," Peter stated, feeling infinitely more confident these days, at least when it came to dealing with the likes of Flash.

Realization dawned on the bully's face as Natalia stood and walked over to him, "My mommy is the Black Widow too. She's teaching me how to fight idiots who don't know how to respect women. She says it's important that I know how because there are too many misogynists in the world." She looked up with a not so innocent smile at the much taller teen whose face was simply of a stunned expression.

Peter and Ned burst into laughter at the sight. It was going to be a good year. The rest of the team arrived, and Liz Toomes cooed a little over Natalia, to the girl's annoyance. Peter sighed, Liz was going to learn quickly that Natalia was big on being taken seriously.

Six Years Later

Peter tugged awkwardly at the bowtie of his tux. He hated these things, though he had definitely gotten used to them, between working for Stark Industries and being the nephew of Tony Stark's girlfriend and then fiancé. He fixed his hair a bit before sighing. It was for Aunt May, he reminded himself. The woman who was nominally his mother in all aspects. He was doing this for his Aunt.

With that, he left the dressing room and stepped into the room where the rest of the groomsmen and the groom were waiting already. Steve was attempting to calm Tony who was pacing impatiently. Peter smiled at the sight. Tony was formerly the consummate playboy. This was a whole new experience for his soon-to-be Uncle.

"Alright, I'm going to check on Aunt May, you guys have this handled?" Peter asked Clint who was attempting to restrain Nathan long enough that he could get the little boy into his tux jacket. George and Joseph had point blank refused to be part of the wedding and were with Bucky, already seated. So, it had been Nathan that ended up as the ring-bearer for this wedding.

"Yeah, we're good. We have a half hour, so make sure everyone is dressed, the rest of us have to start escorting guests to their seats," Clint waved Peter off.

Peter walked down the hall and knocked on the door that held the women. Natasha cracked the door to check who it was before opening it to let Peter into the room. Martha's Vineyard was an odd place to hold a wedding, Peter couldn't help thinking, when the groom was a recovered alcoholic, but then, most of the people attending the massive wedding weren't and Tony was trusted by this point not to fall off the wagon. His life was simply too happy for him to turn back to alcohol as a coping mechanism.

Peter glanced around and smiled at the sight of Natalia and Sarah decked out in flower girl dresses. His Aunt was pacing much like Tony was. She gave Peter a smile, "How are they all doing over there?"

"Good, all the guys are dressed. I just wanted to check-in, make sure you don't want to pull a runaway bride," Peter joked. "I'll help if I have to, but then we might need to change our identities, which I'd rather avoid, having just gotten my first doctorate."

"Oh, I'm nervous, but I know I want this. Tony's pacing too?" May asked, a little relieved she wasn't the only one nervous.

"Of course, he is. Unlike you, he hasn't married before. Never mind that up until you, he had commitment phobia. It will be fine," Laura reassured. "You two have been living together so long already that there isn't going to be much of a change, just a few bits of paper and a few vows."

May nodded and smiled more brightly, "I'm genuinely happy about this, it's just been a while since I was married, you know, and the last time… well no one was going to anticipate an Alien Invasion at that time."

"It will be fine. Everything will go swimmingly," Darcy stated patting May on the back. She and Jane had moved into the Avenger's tower officially three years prior, after a lot of cajoling from Tony. "And if it doesn't, well we have enough bad-asses here to make whoever ruined your wedding regret ever considering the idea."

May laughed at that. Still, she paced a little more, until a knock on the door gave the signal that it was show time. The bridesmaids and flower girls flowed out of the room leaving just Peter and his aunt. Peter kissed her on the cheek, "Uncle Ben would have wanted you to be happy, no matter how you found that happiness." He stated sagely.

"You're right, he would have. Ben was amazing like that," Aunt May gave him a smile. "Well, ready to walk me down the aisle?"

Peter gave a soft laugh, "I've been ready for three years, Tony took way too long to propose."

May snorted as they left the room, "Well, he had some lingering trauma to work through."

"Very true," Peter nodded, recalling how his Aunt met Tony in the first place.

They walked carefully out of the building and down the path until the reached the bushed where everyone else was lined up. Peter glanced at his Aunt again and smiled as the music started and the groomsmen and bridesmaids slowly walked down the aisle. His Aunt looked stunning in a classic, timeless A-line dress, her sleeves just a bit of lace on the very edge of her shoulders.

As Natalia and Sarah turned around the bend, Peter refocused, eying Nathan carefully. The boy stood straight when it was his turn and he puffed out his chest proudly, making May and Peter giggle a little. Then the music changed, May took Peter's arm and they turned the corner. Peter resisted smirking as Tony's jaw dropped open a little. It was hilarious. Of course, he knew that his aunt was equally amused. The make-up had been light, intended to look as natural as possible, her hair carefully braided into a beautiful crown of sorts around her head. May insisted on no veil, pointing out that it was stupid when she was clearly no virgin and Tony knew what she looked like. Instead, there was circlet made of sapphire jeweled hair pins circling around her head, holding the braid in place. Altogether, it made his aunt look more like a fairy queen then a bride, but Peter had liked the look on her.

When they reached the alter, Peter swiftly got out of the way and Tony was a little too eager to take May's hands. Peter went and took his seat in the front row and pulled out his cell to snap a few discreet shots of the couple. Thankfully, neither May or Tony were religious, so unlike Steve and Bucky's wedding, it was devoid of the prolonging prayers throughout the ceremony, making it much shorter as a result. Peter glanced back at his girlfriend a few rows behind him. MJ rolled her eyes and gestured for him to pay attention.

When the ceremony ended, Peter was among the first to congratulate Tony and May, MJ was quick to join him and slid her arm into the space where May's arm had been while he walked her down the aisle, "You know, I like you in a tux, you look good all cleaned up. Of course, I also like you in your other suit too, that's still sexy as fuck." MJ's comments made Peter laugh a little. He was glad that Liz Toomes had pissed off Natalia early in the school year that first year he knew the little girl. It made things… cleaner when he learnt her father was the arms dealer that he had been trying to take down. It also made it less awkward as his previous crush had died quickly at the sight of her being a little too patronizing to Natalia. MJ had gotten in Natalia's good graces quickly though and had ended up being the better choice for a girlfriend too.

Later on, at the wedding reception, Peter eyed Daisy Johnson, who had gotten recently engaged to Sam Wilson, she refused to drink and his spidey senses told him there might be a new baby Avenger sooner rather than later, though, his Aunt was suspiciously not drinking either. He would have to ask her about that later, then he smirked. Natalia could use a little brother or sister, it would keep the tiny mad scientist out of trouble for a little while.

MJ poked him in the side, "What are you thinking about?"

Peter turned and smiled at her, "Just that a few interesting people are avoiding alcohol tonight."

"Oh. Well, that's disappointing. I was hoping you were contemplating this ring that was burning a hole in your pocket," MJ smirked at Peter's stunned expression when she held up the box holding the ring that he had be carrying around for the last few weeks. She could tell that he was trying to figure out how she had gotten it out without his realizing. "I felt the box earlier. I slipped it out while you were distracted."

"Are you going to let me ask, or you going to steal that from me too?" Peter asked finally.

"I suppose that depends, are you going to keep lingering or just ask the damn question that you already know the answer to?" MJ's teased, dangling the box in his face.

Peter snatched it from her quickly and then opened it, "MJ, will you marry me?" He looked so hopeful.

"Oh, I don't know, this ring is awful gaudy…" MJ teased again before taking it out of the box. "But I suppose it will do."

Peter snorted and took the ring back so that he could slide it on her finger, "I suppose I should be grateful that you didn't decide to make a spectacle and use the damned thing to propose to me." Peter kept a firm grip on her hand one the ring was in place.

"I'll admit, it did cross my mind, but I figured it would be tacky to make a scene at your Aunt's wedding. We should probably wait until they get back from the honeymoon to tell them," MJ stated.

Peter snorted again, "It's my mother's ring, Aunt May kept it for me, she told me that if I didn't tell her immediately after you said yes, she would castrate me in my sleep. If we wait a few weeks, she will kill us both."

Steve was close enough to watch and overhear the whole exchange between Peter and MJ. He resisted the urge to laugh when the pair went over to May and Tony and informed them of the good news. Tony wasted no time redirecting the attention away from him and May by cutting off the band, taking over the microphone, and announcing the engagement for everyone to hear. That led to a lot of laughter. Once the commotion died down, Steve looked over to where Bucky was dancing with their 14-year-old daughter, Rebecca. A small part of him, a very, very small part of him, was grateful to Hydra, after all, for all that they had put Bucky and their children through, without their actions, Steve wouldn't be sitting here, truly happy, in a way he had never imagined possible before.

The End
