William was fervently in favour of this plan. Privately, he was of the opinion that his mongoose had been onto something by riding around on Pete's lion all the time. "That sounds wise," he agreed, checking the girls' lavatory for any stray students (or slavering, cannibalistic hideaways) before moving on to the Prefects' bath.
"Should we just drain the tub and block the trapdoor?" he asked, looking at the pond-sized basin of steaming, floral-scented water. They could always swim to the bottom to check the antechamber, but personally he wasn't very keen on diving into anything in the current climate without knowing exactly what he was going to find in there. He hoped the students would feel the same way.
