Hermione would've liked to admit that she'd been harder to break, but she wasn't. A human being can only take so much before they cracked and between months on the run, watching her best friend be murdered before her eyes, weeks in a broom cupboard where she didn't know what her fate would be, and then having her mind savagely ravished by Lord Voldemort, she wasn't at her strongest to begin with. While there would be many more times in the future that she would incur Antonin's wrath when she disobeyed an order from him or because she simply displeased him, never once did she eat in his presence without his permission.
