Calla, who was busy eating, looked up from her small meal in the direction of Kelvin as she heard him think aloud, however she couldn't quite make out what exact words he had spoken. "Keep talking to yourself like that and people will start spreading rumors that you're crazy." she commented with a small smirk before her attention returned to her meal. Being rather lazy at the moment, she leaned against the counter of the table she sat at and stretched her back out as she briefly fixed her posture. 

Calla being Calla, she naturally knew at least everyone's name in the guild. Partly because she was nosey and would bug Kage about it every time she saw a new face at the guild. Plus she was pretty good when it came to names. Of course, she wasn't quite the friendly type which is why her knowledge of guild members usually stopped at there names. For now at least.
