"Pure attempted detective story thinking.  I infer that Leah woke somebody up, we don't see them, neither you nor Emily seem eager to leave Pelican town or to leave the status quo undisturbed or to not wake anybody else up... people where I come from don't usually kill, but maybe Leah convinced herself that you weren't real people, or hadn't finished turning into real people.  She had a lot to lose, the way she sees things.  People don't usually murder where I come from, maybe partially because most people don't want to--but, I bet much more so, because it's hard to be sure you'll get away with it.  Pelican Town, I bet, doesn't have police who can run DNA tests on stray hairs around the site of a murder scene or disappearance.  I never considered killing you or Emily, but I think I'm probably unusually ethical for a person from my world."
