The only thing that really bothered me in this episode was that the two people Raki, Easley, and Priscilla met while nearly Pieta knew that Claymores had ranks, and moreover, that the lowest was present. Earlier in the series, it's made abundantly clear that the common people know nothing about Claymores, other than what they do, and what they charge, and they are headquartered in the ruined wastes of the east (where obviously no one else lives).

Ranks, that Claymores don't call themselves Claymores (name instituted by the common people), "voracious eaters" versus Awakened Beings (something Clare didn't seem to really know having never hunted them previous), black cards, etc. These are all things we learned directly from higher ranking Claymores, or their handlers.
