The frantic, desperately hungry chattering escalated into a screech as he was suddenly attacked by the Dark Boy. He scrabbled viciously at the hand that held his throat, possibly landing a few cuts in the process. The screeches escalated as he was shaken, and then all at once he was dropped.

He fell to the ground with a hard thump and for a moment simply sprawled there, gasping for breath and calming the frantic noises he made. His voice died off and he fell silent for a moment, sharply turning his head toward the voice that was calling out now. He stared at the human with a malignant glow to his yellow eyes, and then lunged back onto his feet, hurrying awkwardly after the Dark Boy.

His chattering started up again as he rush-wobbled past the human who'd called in his general direction, shooting him a hungry glare and going so far as to slash at him as he passed, though he could only feel the catch of cloth on his claws before he was past the human. He stumbled once and hissed as he almost lost balance completely - but managed to regain what little composure he had to begin with, and pursued the teen, hissing and chattering angrily at him, but not going so far as to actually confront him.

Heartless lingered several feet behind, and simply followed.
