EVERYONE loves hitting a balcony after a reception. This be-sashed dude is the acting Mayor of Mons (which is where this balcony is located) and HE IS HAVING THE BEST TIME HANGING OUT WITH HARRY. You and everyone else, dude. I'd love to tell you all the minor scandales and fascinating details of his life, but he doesn't have a Wikipedia page and therefore I guess maybe he's just a hologram.
So much pointing. Anyway, here is Harry's suit and apparently this is part 87 in his attempt to slowly take over William's life, by dressing in an identical manner.
"I CAN ALSO POINT, KATE. Do not fall for Harry's whimsical, point-y ways." Maybe there are MANY POINTS OF INTEREST to be viewed from this balcony. I don't know. I've never been on a balcony in Mons to be able to confirm or deny this.
Maybe this is actually a choreographed dance routine? There IS no better way to bring peace to the world than through dance.
