Don't need to be terribly formal on Halloween, after all. Come on, Tybalt - it might be safer to carry things by hand in this crowd than to try levitating over people's heads, and you're big enough to break trail."
"Great, relegated to being Bigfoot again," Tybalt grumbled, although his eyes danced with amusement. He stood, regretful of losing Severus' hand. "Hold that thought," he told his husband, then he and Remus walked off toward the bar to retrieve food for the rather large and hungry Snape brood.
