Vianna had a very difficult time hiding the amusement from her blue eyes as she watched Ferris slowly turn around and narrow his eyes suspiciously at her, the corners of her lips twitching just slightly as she tried her best not to fall into another fit of giggles. As Ferris then asked what she was trying to say, suggesting that perhaps she wanted to see his 'pale, horrible scrawny Professor-chest', Vianna found it impossible not to smile anymore and laughed lightly at his words, completely amused by such an inaccurate description. "Maybe..." said Vianna, playfulness still sparkling in her eyes. "But... I wouldn't want you to catch a cold either," she said with a sigh, resorting back to her evil ways once again, changing her opinion once she thought she had the boy convinced to keep his shirt off. "I'd be devastated if my adorable, caring Professor caught a cold!" she added, giving him another pout, trying her best not to giggle mischievously as she was dying to do at that moment.
