Laurence
Obviously William Laurence was here. At his wedding. We got married in his dress uniform (bars on the arms instead of epaulettes, no hat), and did not look at all like Christmas next to his husband's red robes shush.
He was all smiles pretty much all day. Lots of laughter. Lots of long, fond looks with Lan Xichen. He likes to dance and while he would've mostly liked to dance with his husband, he'd have happily danced with anyone who wanted to and could help teach the English country dances for anyone who wanted to learn.
He had a fair amount of champagne and was pleasantly tipsy and gregarious.
