Russell didn't have to try too hard; Derek was worn out and couldn't put up much of a fight. He normally spent his moons locked up in the dungeon at Hogwarts, waiting for morning. He was quite fit as a human, at first to ease his transition as a tamer and then just incidentally from racing after various creatures and kids. But as a wolf, he was out of shape. As Russell caught ahold of his scruff he collapsed on the ground, panting, tongue flopped out of his mouth.
