Peter and Wendy
Such a good friendship scene between them! It sort of reminds me of S1, when Linds was going to marry Mr. French, only right this time bc it's Mel she's marrying instead.
Brian gives her the tickets for their honeymoon (do you think he decided this on the spot, right then?). But Lindsay would rather him go and have a good time. It's so sweet that both of them are ready and willing to give up what they want to make the other happy...and it says a lot that Brian was willing to give up his fuckfest tickets as a gift for a wedding he supposedly thinks is dumb. I think part of him, however small, really is sorry that he won't see her glide down the isle...and I feel like the kiss is an ILY and in small part a "goodbye" to his friend, a send-off into married life.
Lindsay gets it completely, and when he shuts the door behind him, says "I love you too, Brian."
