"Can they get at you in the cages?" Heath turned his attention to the telly for about two seconds before he took the cold beer off of his stomach and sat up properly beside Merton so he could drink it. "I'm not sure you can though, mate. They don't let vampires go down in those cages, though. Sharks and scenting blood or something, wouldn't want to make the thing sick."
Mostly, Heath just didn't want to get dragged to go and pet a shark, and that was generally where Merton's little obsessions lead if he didn't forget about them completely in the next few days.
