Squid's BROOKE arrived with LUKE in their first major outing as BF/GF, she wore this dress because she's still a little iffy about showing her scars. She had matching heels and made sure Luke's tie matched her dress. She probably spent the night dancing with him but will have mingled with friends. They gave the couple a gift voucher for a romantic meal for two at their choice of restaurant in the city.
CAROL came to the reception with AMERICA, she wore a soft pink dress, put her hair up and spent the night trying to mingle with people. She probably wound up meeting with GAMORA and NEBULA at some point to talk. CAROL and AMERICA went halfers on a HIS&HER bathroom gift set including soaps, bubble baths, a bottle of champagne & 2 glasses and matching bathrobes and fluffy towels, all marked HIS and HERS
CLINT arrived with GAMORA for the ceremony, they were almost matching but CLINT went with a dark blue shirt instead of blood red like greenie. He would've met up with NEBULA and NAT after the ceremony, he would've been at the reception on and off because there was 100% a lot of sneaking off with NATASHA and he's not apologising for it. They know you've got your wedding rings, but CLINT and NAT got them promise rings for him and her.
DAPHNE came with VELMA, and wore her signature colour with light purple heels. She undoubtedly got VELMA to dance a few times and was mingling a lot. She would've danced with anyone who asked her to.
ELLIE came with GWEN, she wore this black mesh panel dress with low-top Chuck Taylors, and brought a carefully build origami tower of 1000 cranes adored with two swans with their necks entwined. The couple can use the 1000 cranes to make a wish.
JULIAN wasn't really sure about coming, but attended the reception. He was actually a little less formal than he usually is. He would've likely sat quietly, but made conversation with anyone who stopped by.
BUTTERCUP, EMMA & ST JOHN didn't attend for various reasons.
