Grady arrived just in time for the ceremony, stood quiet, and based on whatever Pepp and Jo were being told to say tried to figure out where in the ceremony they were cause he doesn't speak a lick of French! He had a semi smile at times that anyone who's known him for years would know isn't his real one (Pepp and Meg I think would notice if they wanted to.)
Afterward he went out for ONE drink and a bit of food with the gang, and only on prompting so someone plz have prompted him, and cut out before the others went to the "high-energy dance places." But he'll have promised to show off moves some other night and claimed not wanting to impose on his baby sitter much longer. Gift to the both of them was ..gah I dunno. I'll figure it out later. But he mustered up enough happy to pass on a "make sure they're sober" joke that Pepper would get as something Allen had once said to them ('He'd have to be drunk to get married'). One of those big, manly hugs with the pat on the back with a 'congrats, mate' to Pepp and another one for Jo if she'll take it before he apparated off to make sure Ted/Andie/kidlets were still alive.
