John has been painfully quiet throughout this whole ceremony. Maybe he feels odd being in attendance — he hardly knows the happy couple — or maybe he's just not quite ready to accept that he's here because he feels like he needs to prove he's not reverted back to a social awkwardness that's plagued him since he joined the police academy.

Dressed in his best — that's the clothes he arrived in, basically — he spends a good amount of time with a glass in one hand and his other hand plunged into the pocket of his trousers to keep him from fidgeting too much. He's people-watching and quietly contemplating his place in the universe (which happens to be lightyears and lightyears from where it used to be in more ways than one).

And, in fact, he probably wouldn't say anything to anyone if he hadn't just seen someone drop a drink moments before. "Hey, hey, watch your step," he says to one person in passing. The night will be full of helpful, handy hints like that.
