Do we know it’s a wedding? I mean, it could be, ... but it could also be a high school reunion or something like that. I guess I’m missing something...? Even if it is a wedding, it clearly isn’t either of them getting married. So that means it is likely one of their friends getting married - the ‘cool’ lesbian girl, the ‘cutesy’ girl, the older ‘soccer’ guy, the ‘cross dressing’ guy or his younger sister. All are possible. Personally, I wouldn’t mind if it ended here... with our main characters reuniting at a unspecified social event... leaving a bittersweet, yet hopeful, open ending.
