AN: Enjoy!

The trip to the Avengers Compound was relatively uneventful. Just a stop for lunch, a few diaper changes for the boys. Vision was glad for the uneventfulness. It gave him time to think about his 'Best Man' dilemma.

Unfortunately, all the thinking in the world did not actually help with his problem. Because, well, Vision was a soft soul and he knew that, beneath the armour, and the gamma radiation, and the masses of Asgardian muscle, his three 'Fathers' were actually soft souls too. He didn't want to hurt any of their feelings by not choosing them to be his Best Man.

Vision sighed deeply. While he had hoped to make his mind up on the trip over, he was still no closer to a decision as he pulled up outside the compound. The gates opened quickly, implying that someone had already been waiting for their arrival. This was confirmed when Natasha met them as they parked the car outside the main building, rushing to the back seat.

"Where are my little Godsons?" She threw the back door open, unbuckling Billy and Tommy's car seats so that she could scoop both boys up. "Hello Myshka, Zoichik. Auntie Nat has missed you."

"And what are Vision and I, ficat tocat?" Wanda smirked as she got out of the car.

"Oh, of course I missed you too.." Nat chuckled, "But you and Vision just aren't quite as cute."

"An' Nat!" Billy cooed, clapping his little hands, and making his Aunt's eyes light up.

"See? He's adorable."

"Okay, you've got me" Wanda admitted with a smile. "There's just no way we can match their level of cute, right Vizh?"

"Oh, definitely not" Vision agreed, pausing as he spotted a fresh, but familiar scorch-mark on the compound's front lawn. "Is Thor here?"

"Yeah, he rainbow bridged himself here from New Asgard this morning after Wanda called ahead to say you might need to talk to him" said Nat.

While Vision loved Wanda too much to ever glare at her, he most definitely frowned.

"What?" Wanda smiled sheepishly. "You really might need to talk him."

"I might.. But I haven't made a decision yet. We might have dragged the poor man here for no good reason."

"I feel like I'm missing something.." Nat raised an eyebrow as she carefully re-positioned the twins in her arms.

"Vision's having trouble choosing which one of his 'three dads' he wants as Best Man at the Wedding" Wanda explained.

"Oh.. Well, none of them are here right this second" said Natasha as they headed inside, "So you've got a bit more time to think about it."

"Where are they?" Wanda frowned. She'd made sure the day of Tony's regularly scheduled visit to the compound coincided with their own visit.

"Tony had a fly-by scheduled for a Make-A-Wish kid, and when Thor showed up he thought it would be cool to take him along" Nat explained. "Bruce went too because he thought Thor needed a more responsible chaperone than Tony."

"Probably wise.." Vision sighed.

"The rest of the guys went to pick up some extra supplies for your visit.. The Spider-kid is here, though.."

"Peter?"

"That's the one" Nat nodded. "He's in the lab mixing up some of his web stuff. Well, the boys have an appointment with their aunties" she smiled at the twins, walking off. "Auntie Carol and Auntie Hope will be happy to see you too! Good luck with the Wedding thing, Vision.."

"Hmm.." Wanda gave Vision a quick kiss before hurrying after her friend. "Hey Nat, speaking of Wedding things.."

Vision watched them go, then, after thinking for a moment, headed to the Lab. Maybe Peter was just the right outside observer he needed.

From both his past experiences as J.A.R.V.I.S, and his present life as Vision, Vision was profoundly aware of the fact that a lab that either Tony or Bruce worked in was likely to contain something dangerous, and a lab in which both of them regularly worked bumped up that 'highly likely' to 'almost definitely'.

So, he was quiet as he entered, careful to ensure that he didn't step on anything dangerous. Making his way through worktables and gadgets until he found Peter working at one, Vision announced his presence with a quiet clearing of his throat, so as not to startle the boy (or set off any of said gadgets. Vision hadn't been here for a while, and he wasn't sure what additions Tony had made to the compound's security in his absence).

"Oh, hey Vision.. Mr. Stark said you were coming Today" Peter looked up from his work, and Vision's synthetic heart was warmed to see that the boy looked genuinely happy to see him. "Do you need the lab? I'm almost done here, I'll get out of your way.."

"Oh no, that's not why I'm here" Vision chuckled. "And even if I were, there's plenty of room for both of us. I'm actually here to ask your advice on something."

"Advice?" Peter's eyes widened. "You want my advice, really? About what?"

"Well.. due to the rather strange circumstances of my coming into existence, I effectively have three Fathers.. Mr. Stark, Dr. Banner, and Thor."

"Whoa.. That's cool."

"I suppose it is.." Vision smiled. "But, it leaves me with a rather large problem. My Wedding is coming up, and I can only choose one Best Man."

"Ah.." Peter winced. "That's a tough one.."

"It is" Vision sighed, sitting across from him. "So, what should I do?"

"Hmm.. Maybe make up a pros and cons list for each person? Like, Mr. Stark has plenty of money to help you pay for the wedding and stuff.."

"Mr. Stark already pays me plenty" said Vision, "But he was probably the first person to believe in what a force of good I could be."

"And he could probably throw you an awesome Buck's party."

Vision paled.

"I definitely do not want one of those."

"Guess that's a con then, huh?" Peter frowned. "What about Thor?"

"Hmm.. Captain Rogers almost attacked me when I was born, but Thor stopped him. I admit that made life easier for me, as if Captain Rogers had attacked, I can't promise that I would not have panicked and reacted unfavourably.."

"On the other hand, Thor's a pretty big party guy, so that's a similar con to Mr. Stark.

"That is true" Vision nodded.

"So.. Dr. Banner?" Peter mused. "Really nice guy, but Wedding planning can be stressful.."

"And stress does not agree with him" Vision sighed again. "I know. I'm still really no closer to a decision.."

"Hmm.." Peter, rather eager to help, thought for a moment. "Maybe don't pick any of them."

"What?" Vision frowned.

"Don't pick any of your Dads to be Best Man, and then none of them will think you're playing favourites.."

"Hmm.." Vision, thinking too, could almost see Peter's point.

"They can be your Groomsmen, then pick a non-Dad person to be Best Man, like Captain Rogers, or.."

"Peter!" Vision's eyes lit up.

"What?"

"You, Peter!" It was the perfect solution. Tony, Thor, and Bruce all liked Peter far too much to be jealous, and the three of them could still be involved as Groomsmen. "Will you be my Best Man?"

"Me?!" Peter was surprised.

"I don't need a Wedding Planner, or a Buck's party.. just someone to stand beside me on the day. Please?"

"Well.. Are you sure? Because if you are.. Sure!" Peter grinned. "I'll just have to hire a new suit."

Elsewhere, Tony, Bruce and Thor sat in the back of a car travelling back towards the compound.

"So.." Bruce asked. "Have we stayed out long enough?"

"Did it work?" said Thor eagerly.

"Friday, progress report" said Tony. "Show me the lab."

"Yes, Boss."

A video feed of the lab lit his glasses. Vision had stood to give Peter a hug.

"Hell yeah, it worked. They're hugging it out as we speak!" Tony grinned at Bruce and Thor, rather proud of himself.

Their Robo-son was a soft soul at heart, worrying so much about what his Father's would think. When Wanda had called ahead secretly with her concerns, he knew he had to fix the problem.

The three currently in the car knew that none of them were the Best Man Vision needed. They could be part of his day in other ways. Peter, however, was the perfect candidate, and it would mean so much to him.

All Tony had to do now was make sure the compound was stocked with Natasha's favourite Pop Tarts as thanks for pointing Vision in the right direction
