‘The man of war will end this house.’
Obviously foreshadowing. I wonder what he means by “end this house”. Literally? Possibly. Maybe something happens and the house is burned down? More likely figuratively. I think whenever Pierce moves out, so might Emma, though I can’t imagine what circumstance would cause her to leave Lapis Lazuli. Then again, this could be a red herring and Pierce is not the “man of war” at all.
That said, this does make me believe that Emma will eventually no longer live in Lapis Lazuli.
