Percy & Alicia & OPEN
Percy spotted Liam and Islan before he did Alicia. Lucy greeted them with squeals of joy, then between gross-out touchings, she showed off the wings of her winged horse costume which were charmed to flutter and flap in time to her movements, as well as a tail charmed to move back and forth. He didn't have to be within hearing range to know Lucy was asking the twins about their costumes, and as he highly suspected at least one of them had Muggle origins, he could already anticipate an argument with Allegra over the Muggle knowledge.
"Happy Hallowe'en," he replied with a nod. He looked down and lifted up the tie he was currently wearing, which featured a number of multicoloured automobiles, and winced. "Thankfully, today is the last day. You look lovely, by the way. How were the twins with the excitement?"
