We have two debatable examples of Keiko possibly threatening us with harm because we offended her, and probably half a dozen when she responded by closing in on herself and/or diving into the Frozen Skein. She is probably a much bigger danger to herself than to Hazou at the moment.To expand, we've already seen Keiko try to kill us at least twice, for much smaller transgressions. That may have been been entirely for comedic effect, but I would prefer to hear it straight from the QM's mouth(s) before I assume that she isn't going to attempt to at least commit bodily harm to us.
Notice, also, that she took the time to give us the scroll and let us read it. This is not a crime of passion.
