Normally such a short night, even one filled with Rose, might leave him yawning and hard to get going in the morning. But today was Halloween, and it was Dennis' birthday, which they'd been hoping to be able to celebrate properly for quite a while, without letting him know it, of course. And of course there was dressing up later that night, and getting to go out.
Rolf hmmmed and pondered for a moment. "Let's go with Belinis," he said after a moment. "I like those better, adn I think he might too." Though they had stuff for both, so if it turned out wrong, he'd just pop back to his flat to get it. After all, must back the birthday boy happy!
