Justin, Ernie and Hannah (Puff Trio Time)
Justin has spent the night having fun, going around from person to person and handing out leis with as many variants on the 'Would you like to get lei'd?' line as possible. He of course meant every single one of them, but he always said them in such a way that people could roll their eyes and fob it off as a joke if they weren't interested. He was glad, however, at his choice in outfit - the grass skirt, no shirt, and straw hat and leis - as the more people entered the Atrium, the warmer it got.
He'd had so much fun that he eventually realized he hadn't even sought out his best mates yet. It didn't take long, however, particularly with Hannah's gorgeous Hufflepuff-coloured gown. He made his way through the crowd and approached them from behind, then suddenly slung an arm over each of their shoulders and hugged them to him.
"I've been having a wonderful time!" he said, the few drinks he'd had beginning to show in his voice. "How's yours been?"
