Johnlock Wedding Headcanons:
Double proposal!
John and Sherlock both separately purchase rings. The proposal isn't a complete secret on either end though, as Sherlock deduced that John had bought one and John found out one evening when out for drinks with Mike Stamford
John would tell Mike all about how he thinks it's time. He's bought a ring. Mike would then absent-mindedly say "You're the second person to say that to me today"
They both wait patiently for the other to propose, wanting to see what he has in mind for a special proposal. But because they're both being polite and waiting, it takes months after they've both bought the rings for it to finally happen
Eventually John gets impatient and decides to just propose to him
One day, in the middle of a case that isn't too serious or time sensitive, John sets his plan into motion
In the lab of Barts Hospital, John stands in the exact spot he stood over a decade ago and waits. When Sherlock is done at the microscope, he walks over to John. His work is done for now and it's time to go home. But John isn't going anywhere
John attempts to give a smooth transition into the proposal, but words fail him. So instead, he gets down on one knee, pulls out the velvet box, and asks the question that he's been dying to ask for about six months now, "Sherlock Holmes, will you marry me?"
Sherlock is almost rendered speechless as he blinks at the love of his life, stunned. But he quickly recovers and remembers his part of the plan. He clears his throat, attempts to blink away the moisture forming in his eyes, "That depends, John," he pulls out his velvet box and bends down on one knee, "Will you marry me?"
John finds moisture creeping it's way into his eyes as well, a strange lump forms in his throat as he chokes out "Yes" to which Sherlock responds with his own "Yes"
They then slip the rings onto each others' fingers and fall into an embrace, followed by a deep, passionate kiss. By this point, Sherlock is crying. He doesn't see a point to hiding it. He just lets it happen. They pull away for one second to share an elated giggle, before pressing their lips together again
Molly is of course the first person they tell, as she walks in during their kiss. They are both bursting to share the great news with anyone and everyone, so they both blurt it out in almost perfect unison within seconds of her entering the room
They decide to take the rest of the day off, so that the second Rosie gets home from school, they can tell her. She is of course ecstatic when they tell her and starts planning an imaginary wedding for them on the spot
When they tell Mrs. Hudson her response is "It's about bloody time"
The date for the wedding is January 29th, 2023 in honor of the day they first met
The Pinterest-esque signs that have the date the couple met, the date they proposed and the date of the wedding, will be there. But inspired by Indefinite Lines by @arwamachine, the number of days they've been in love will also be included
For Example: 29/1/2010 - The First Day, 30/1/2010 - The Day We Fell In Love, 11/6/2021 - The Day We Said "Yes", 29/1/2023 - The Day We Said "I Do", 4,748 Days In Total
Rosie would be the Flower Pal (Shout out to Sims 4 and your adorable gender neutral for flower girl which I am so going to use from now on!)
Archie would be the ring bearer again, because let's face it. There's no way that John and Sherlock know any other children to fill in the role. Archie would be about 15 now, but he'd agree to do it because Sherlock. Because he's still waiting for the headless nun picture he was promised
Sherlock does keep his promise and shows him the picture during the rehearsal. It was well worth the almost nine year wait
Archie and Rosie become friends and have a lot of fun being the only children at the wedding. All the shenanigans they get up to...
Lestrade is Sherlock's best man and Mike is John's best man, although they spare Mike from having to do a speech
Lestrade tells the story of how the duo fell in love during his best man speech, as he was a witness to their relationship from the start
Sherlock sits Mycroft and Lestrade together during the reception because he ships Mystrade so hard and they haven't made any efforts to meet on their own. So he introduces them to one another and the slow burn begins...
Although they don't want to admit that they have a crush on each other, they do agree to dance as there's no one else for them to dance with. The magic begins during their dance
Also bonus Mystrade headcanon I want to sneak in. Mycroft proposes to Greg on Christmas day the next year. This is significant because Christmas day, 2010 was the day that Greg found out his wife was cheating on him. Now that day will be remembered as the day Mycroft proposed rather than being tainted by his ex
At the wedding, there is a seat reserved for Mrs. Hudson with a sign that says "We know you'd be here if Heaven wasn't so far away"
I don't want to bring down the mood of the post, but since Una Stubbs died in real life on August 12th, 2021, I made that Mrs. Hudson's in universe death date as well. As sad as this is, she was 84 years old and damn she lived a long life
So in universe she lives long enough to see the dynamic duo become engaged. She lives long enough to see her ship sail
RIP Una Stubbs
I'm definitely stealing this from someone, then again most of these headcanons I'm technically stealing
John goes first with the vows. Sherlock's vision becomes blurry halfway through
Sherlock struggles to get through his part of the vows as he attempts to talk around the sudden emotion building in his throat
Sherlock's wedding vows will include the line "I was so alone and I owe you so much" which gets the tears to come out of hiding as John is reminded of that time, when he'd thought he'd lost Sherlock forever
Sherlock holds John's hand, to ground him and remind him that he hasn't lost him. He's still here
To offset the emotion a little with some humor, another headcanon I'm stealing is that the officiant says Sherlock's full name when they ask him if he takes John as his lawfully wedded husband, because in all of his meticulous wedding planning, Sherlock forgot to tell the officiant not to say his full name
"Do you William Sherlock Scott Holmes, take John Hamish Watson..."
it throws the duo off for a second, but there's no point in fretting over it. The wedding must go on
When it's time to kiss, they are both fully crying. Tears of healing and bliss as they finally reach the moment they've been planning for years. The point that at many points throughout their lives they never thought they'd ever get to see
Sherlock would go out of his way to remove as many of the heteronormative and amatonormative traditions as possible
Even though he's in a romantic relationship, going as far as to get married, he's still greyromantic and can't stand all of the silly traditions
They both take Watson-Holmes as their last name
