Wedding Headcanons

Notice that before the ceremony, the grooms served tea to their family. That's a Chinese wedding tradition that my cousin also have at her wedding. 

I've been kind of obsessed with weddings lately. While I fully support the idea of same-sex marriage, I honestly prefer the pomp and circumstance rather than knowing the actual marriage part. I know what marriage entailed and at this point in my life, I have no plans to get married. While I don't mind dating, I have no current desires to marry. I think one of my cousins is going to be a bride sometime in the future, considering we actually met the guy at a family gathering and family gatherings are a huge thing. And even then, that might not actually go through with a wedding-thus-marriage.

I'm just going off pair-by-pair, I supposed. I'll add when I think of a pairing.

Note that these probably include non-canon couples especially if/when canon debunk it.

Klance: I will update this as the series go on. 

Please note that this concerns potential thoughts of the future seasons and yes, this takes consideration of the major character development and probably some major plot developments.

• Lance prepared one of those big marriage proposals (like fireworks) but it was Keith who proposed first...spontaneously because he thinks it is natural. Lance still proposed anyway.
• Technically, it's a destination wedding but it's actually a wedding with a local involved. 
• Both Lance and Keith planned the wedding; mostly Lance but Keith still input something or put his foot down when ideas are too ridiculous (like a huge wheel or an artist). The overall atmosphere was semi-formal. 
• Wedding rings were engraved heartbeat rings. 
• The theme is the relationship, the progression and thereof. The color scheme is red, blue, and black. Lance is making sure it's not looking like Fourth of July. The flowers are red. The bridesmaid dresses are blue while holding the red flowers. The groomsmen wore black suits with the mismatched blue/red tie/bow depending on the groom's side. 
• The cake is wildly different (a four tier separated with each tier almost touching each other) and Hunk needs to take consideration of the temperature and the venue (outdoor beach open-top tent wedding in Varadero Beach). Instead of being stacked on top of each other, Hunk decided to make a 'staircase', leading to the apex of the relationship. The topper is basically a specially made figurine with the couple in their Paladin armor. While the wedding colors are there (red, black, blue), there are also purple and orange. The cake showed the progression of the relationship through colors. The first tier has an orange frosted line at the very bottom that slowly climbed into blue; it's blueberry filling. The second tier still has a shade of blue but grows into the red; this cake is red velvet with strawberry. The third tier was a red and blue in an almost watercolor fashion; this tier is strawberry and blueberry. The last tier is blue and red turning purple with the frosted line as chocolate black; this is chocolate. The couple fed each other a slice of the third tier. Each cake was connected by chocolate sculptures of the Lions they piloted painted with edible. 
• His moms and little brother helped with the cake as well. Hunk was stuffed with Best Man duties, the chef of the reception dinner, and now cake duty. 
• Alien guests stayed in the castle-ship while there is a hotel specifically for the human guests. Lance's family stayed either in their own house or the family house. The grooms stayed separately before the day of the wedding. 
• Before the ceremony, they did Japanese wedding traditions; the sake ceremony for example. Shiro personally bought the sake in his trip to Japan to meet with relatives. 
• Private Ceremony is at Varadero beach with close friends and family, held in the afternoon. 
• Vows are incredibly sappy, especially from Keith's end who rather than sprout out flowery vows, he bluntly stated the truth of how much Lance meant to him and Lance in his life. 
• Reception is also at the beach with an open-top tent, with hanging chandeliers. The newlyweds wanted the guests to enjoy the stars. They also invited Shay, Kolivan, and other aliens they befriended. 
• Shiro's Keith's Best Man and Hunk is Lance's. Allura is also one of Lance's wedding party alongside his siblings. I fell in love with the Allance/Allurance dynamic in S3 and hoped that it continued. Pidge and Axca are part of Keith's wedding party alongside Lance's other siblings. His nieces are the flower girls and nephews are the ring-bearers. 
• Lance's parents walked him down the aisle while Shiro walked Keith. I am making Shiro walk down Keith because I don't know at this time would Keith let his parents walk him down. 
• Hunk and Lance's family who even has the culinary talent was in charge of the reception dinner. Hunk wanted to make the cake so badly; Lance and Keith knew that he'll make the perfect cake anyway and after trying on flavors that he wanted to add to each tier. 
• A mix of Japanese and Cuban culture into the mix; this is an interracial couple after all. Since this is a western wedding, they still chose to implement certain Japanese wedding customs. This is also part of the reception's dinner as well. Yes, there's an open bar that also has an alien bartender who mixed drinks for the aliens or any human willing to try. Thankfully, the bartender is also ethical so he will make drinks for the adults or the drinks acceptable after getting quite a discussion with the grooms and wedding party. 
• Shiro and Hunk gave embarrassing Best Man speeches although it's still heartwarming. 
• Lance wanted a big wedding that he went all out with. There were monograms on napkins/programs/guestbook/etc, practical wedding favors that he knows for certain the guests will use (notepad), and so much more. The color scheme was black, red, and blue. There are other wedding traditions such as the first dance, bouquet toss 2x (one was tossed to Shay and the other to Allura), unity ceremony. Hunk was blushing all the way through. Tables designation were actually places important to the pair; the seating chart was mostly pictured with the names listed below. The main table is actually Team Voltron in general with the grooms' chairs having their respective color ribbons (Keith has a red/black) and Lance has blue/red with the red tying them together... Now that I realized that, it's almost like the red string of fate.
• The grooms have two speeches. One as a thank you and the other was a toast to their parents or family figures. This does not include Team Voltron though. 
• There's crowd games as well as games involving the grooms. There's even a game involving the grooms to kiss at the reception. Shiro, Pidge, and Matt tried to abuse it in a way that didn't look too suspicious. 
• There are wedding videos and photos from the hired photographers, one of which was short and the other was long. There is one similar to the Tiff and Case Wedding Video, showing the important parts. 
• Coran wanted to wed the couple so he actually went to get a license to marry them. 

As for the Nation-tans, if the country they represent ever have same-sex marriage, they will take it gladly. Both Alfred and Arthur married in every state that has same-sex marriage available before the Supreme Court's decision where they then married in the remaining states. If one of the countries still banned gay marriage, then they'll marry in their significant other's country if they have it. If either didn't have it, they'll wait. Knowing the Nation-tans' petty grudges, I don't think they'll want to marry in other countries. The show may look like it pushes xenophobia when really these guys can only spend time with each other because of their lifespan and they don't really hate each other as they proclaimed, judging by the comics. I'm by this headcanon.
