Everyone feels offended and they think maybe the others got invited but the truth was nobody did.
They eloped winter break junior year, but everyone thinks they got married after graduating.
Until Bitty is stressing out planning his and Jack's wedding and Ollie is like "this is why we eloped junior year" and Bitty freezes and stares at him.
"yeah. My student visa was expiring for the year and we had plans to get married anyways, so Pace' suggested eloping earlier than planned so I could get a green card. Fuck, Tango was literally the only one there as our witness and to tell immigration "yeah they genuinely love each other, it's kinda gross how in love they are with the PDAs" so. We never had a real ceremony, just did paperwork for it. It helped that we were broke college students who had been dating since our freshman year."
He texts the others asking if they knew.
They are all HORRIFIED to know they've been thinking the worst of Ollie and Wicky when the only person who went was the freshman that was the honest and genuine tadpole that Wicky pretty much adopted, and probably because there was no way immigration would not believe the kid.
Bitty hesitantly asks if they'd want a ceremony, and Ollie shrugs.
"it's not a big deal to me overall. I think it'd be nice, but I don't need one. I think Pacer would like it though, but his family is also kinda fucked up so I don't know for sure how he'd feel about it. I've offered though. He said no."
"He and his cousin planned their weddings when they were eight, Bitty. He wants a ceremony. He doesn't need one, he knows that, but he wants one, he just doesn't want Ollie to think it's something he needs to do to like, prove they love each other or something. It's from the fucked up childhood. His mom was kinda stupid. Said weddings were proof that they love each other. So Wicky says no when Ollie offers 'cause he remembers that and doesn't want Ollie to feel like he has to do it as proof, because he already knows Ollie loves him. It's stupid. People are stupid. Why are people so stupid?"
"Good Lord, that's the million dollar question, Tango."
And so he talks things out with Tango.
Tango gets in touch with Wicky's cousin.
She gives him the old baby wedding planner they did as kids, and the one Wicky had started when he and Ollie first made plans to get married after graduation (the baby one was for cute little laughs at what 8 year old Wicky wanted, it wasn't actually what Tango asked her for. Nobody is complaining).
She sits Ollie down. Tells him what their moms told them as kids, and that Wicky will never tell him he wants a ceremony because of it, and especially since they're already married.
So Ollie has to finish planning things. They can have the ceremony on the day they actually got married ("Make it romantic! He'll love it!") And it can be in their backyard, even ("where doesn't matter, so long as the people you both care about are there!").
SMH is invited, that much is clear.
Bitty is Ollie's best man, Tango is Wicky's, because Ollie knows Wicky wouldn't want anyone else there unless it's Johnson (which is true).
But Johnson is allowed to wed people legally, they have no idea why, but he can, and Ollie knows Wicky would LOVE that.
The ceremony really is in the backyard, and it's covered in snow, and Wicky comes home from work to their friends and families over and holy shit Ollie did all of this?!
And his dad just grins, gives him the suit he got married in, and his own father got married in, and his father had married in, and Wicky is crying by the time he's standing with Ollie at the end of the aisle, with Tango as his best man, and Johnson is the one marrying them.
He whispers thank you before Johnson starts talking.
It's absolutely everything he could have wanted for their wedding.
