Karifean referred to people the same throughout the flavour text. The blond man was the blonde man throughout, as was the old man. A girl was referred to the same way in both the protect and the kill description. Lends support to the idea that the girl mentioned in both paragraphs are the same. Or maybe it is a red herring.

That doesn't mean that there is only one girl in play though. If we assume that the girl is the same in both, that brings a total to 7 players mentioned. Two players did nothing during the night. One of them could be a girl.
