Justin was dressed comfortably in a white button-down and jeans, his hair loose and falling to just shy of his collar. While he wasn't feeling incredible, he was certainly feeling better after the time he'd spent with Anthony. He closed his eyes and let the sea-salt wash over him for a long moment before he stepped inside. The music and the gaiety immediately lifted his own mood. He'd been deprived of that for so long, and combined with seeing so many people from Hogwarts at once, it was nearly too much.
He steadied himself with the help of a fruity pink cocktail, and started weaving aimlessly through the house. He paused upon seeing an unfamiliar mane of obviously Weasley-red hair. A relative? He was wondering who it might be when they turned in profile. He smirked a little to himself, and it came so naturally he was a little amazed. He stepped close, to one side of Ron, and spoke over the music.
"You were so jealous of my long, pretty hair you decided to try it for yourself?" He asked with that same slight smile. It was good to see him, good to see any of them, he actually wanted to burst into laughter, but it still caught in his throat, and he took another sip of his drink.
