William -- no, not William, the human, the wizard, no names were needed for this, dammit. Anyway, he'd just waved his wand in the air, but nothing had happened, apart from the few snowflakes that had been blowing about turning to rain. Gerard didn't much care about that. There'd been no explosions or jets of flame, nothing painful or distracting. Really, Gerard was overall unimpressed -- but then, the man apparently knew enough to retreat into higher and thinner branches just when Gerard had been about to make an attempt at climbing up after him. One point to the scrawny human.
He swiped his wet hair out of his eyes and resumed pacing around the base of the tree, scowling up at his quarry, and then amidst the dripping and rustling of tree branches, there was a different sound. A crackle of ice, a crunch of snow. Gerard snapped his head around, nostrils flaring, and then bared his teeth in a smile.
Something was moving nearby, something big. Something biteable and not in a tree, but on the ground. Excellent. He couldn't see anyone, not yet, but they were there, watching him, he could feel it in the rise of his hackles and the scent of the wind.
He melted back into the shadows of the encroaching forest, not too far from his friend in the tree, and waited to see what the new human would do next.
