So as soon as the professor man began the lesson, he asked them what they would do if they were without their wands and in danger. Firstly, he hadn't been parted from his wand since he got it, but if he was disarmed, he supposed it made sense. Also, was he really asking them how they would react if they were muggles? Having thought he was a muggle most of his life, he had a relatively good idea of how to react if something happened.

Yup. Raising hand. "If the person in question is bigger or tougher, they'd also likely be heavier. Which means that they would have a greater inertia. In which case I could probably use either my speed or their centre of gravity against them." Yup. That was the scientific viewpoint. Playing dead didn't normally work on humans. "If the attacker already had a hold on me, I'd drop to the ground which would cause them to -y'know- fall over. But otherwise the SING thing works too." Brilliant idea, that one. He'd just write it down for future reference.

As for wandless magic, Brian probably wasn't going to try just yet. He was having enough issues with regular magic with wands, something that would require more concentration seemed unattainable at the moment.
