The name meant nothing to Philia, at least for the moment. From the context, she could likely assume that not only was he a priest serving under the Cardinal at St. Steven's Cathedral, but also that he was more aware of the darker side of the world than most priests - most likely involved in some sort of supernatural business. 

The homunculus' question, however, seemed to displease Karen, as for the first time since the pair arrived in the Cathedral her expression twisted into a minute frown, though the expression swiftly faded. When she spoke, however, there was a hint of tension in her voice. "Alas, Father Josef knows more about tending to the souls of lost lambs such as yourselves than about any such shadowy figures who would invite such dangerous individuals into our fair City of Dreams."

Well, that seemed to imply that Karen was not [i]actually[/i] answering to this 'Father Josef' directly. But before either Servant or Master could consider that in more detail, the nun continued. "In any case, I had thought that the Einzbern clan was [i]sure[/i] to be keeping tabs on all individuals who might be involved in such an endeavor." She adopted a tone of mock-surprise, though her expression remained as bland as usual. 

"Perhaps you might consider seeking out your own clan's records - ah." She lifted her hands to her cheeks in a gesture of (likely false) embarrassment. "My apologies. I had forgotten." [i]That[/i] was a clear lie, but it seemed rather pointless to challenge her on it.
