The information is too interesting for Peridot to truly beef it, even if Herbert doesn't laugh. He reconsiders the small woman, not as an overenthusiastic costume party attendee, but as an alien this time. An inorganic alien, somehow. It would be incredibly fascinating to get his hands on a dead member of her species to determine exactly how that translates to the interior. Are organs not required? Could he translate anything from their method of functioning to prevent death in humans?

He really wants to ask about the other part, though.

"Do you mean this isn't Earth?"
