When Ammy asked about the staffing, Lydia replied sadly, "Many instructors, and students, come and go. Though it seems like more often than not, most are going."
She then listened intently as Ammy mentioned the rumors and noticeably winced as she spoke the word 'vampire'.
When Ammy mentioned the 'sunscreen', Lydia knew that she was only trying to help, but her eyes were still narrowed in cautious hesitation. "If I did have such an allergy..." she began, always determined to deny, "I do not believe I, myself, would be willing to take such a gamble on my life to test it." After pausing momentarily, she continued, "But I do know of some acquaintances that might be willing to try it."
She realized that her defense of 'I have a friend...' probably sounded suspect, but her words were true. Although Lydia hated this curse, she did not want to risk her life for a possible cure, and she did know a few others of her kind that would jump at the chance for an opportunity to roam in the sun once more, no matter the risk.
