There was going to be a wedding - no details about who or anything like that, but Gregory didn't care. Help set some things up and clean afterward, that's all he'd been told. After he put up the chairs and tables and shit, he kept to the kitchen for the most part, nipping from a bottle of beer, even though it was early in the day. When people started coming in, Gregory peeked out of the kitchen and saw a bunch of those stupid red-headed Weasley folk... Hermione was there, so was Harry.
Huh.
He went back to sitting in the corner and drinking until the music started playing to herald the beginning of the ceremony. Again he peeked out, and saw it was Hermione and Ron standing there at the front, saying their vows.
Huh.
He didn't feel any particular emotion for or against them. Sure, they were enemies in the past, at Hogwarts, and yeah, he was kinda sore at the things they'd done to him, but more or less, Gregory just felt meh.
"Stoopid Weasleys," he muttered to himself just because. "Wit their stoopid red hair."
Then he saw it: in the far end of the bar there stood a whole fucking PILE of cupcakes! And more cakes! And MORE!
"Maaaaan," he drawled, his eyes fixated at the spot. He just had to get one. Or two. Or seven. Not now, though. There wasn't a way for him to sneak over there, unnoticed, and though his manners often left something to be desired, even Gregor knew better not to walk right through a wedding he wasn't invited to, just to get to the dessert table. 'Sides, the boss would probably get pissed off.
Gregory waited for the ceremony to end, all the while meditating on those cupcakes. A peek out the door confirmed that the ceremony was over and people were mulling around, celebrating. Now was his chance. Emerging from the kitchen, he moved slowly along the back wall, not really trying to sneak, since he wasn't clever enough for that, just trying to be out of the way as he steadily reached his goal.
