Risu looked at Alex shiftily. "You have a devious mind, Mr Miner," he said, making a mental note never to supply any advice, atomic batteries or semi-conductive bits of metal to the kid. He'd shrink the Whomping Willow and sell it as an "especially lively bonsai tree" to some poor Muggle in London.
That's exactly what he'd do.
"Shrink rays..." he said musingly, a grin playing on his lips. "I'm afraid I'm not authorised to say whether those exist or not." He clapped into his hands. "And what a pity, Mr Miner, that the lesson seems to be over just
now."
He couldn't suppress a little smirk. "Homework will be on the blackboard, make sure to tell the fellow students in your house if they missed these two lessons, aaand..." Risu glanced at the clock on his desk. "Well, I will be around for at least another 30 minutes or so to answer your questions if there is anything unclear from what we talked about. Great job, everyone, I'm really pleased with how much you understood."
He nodded, satisfied, and turned to wave his wand at the blackboard. Scrawled writing appeared.
