The old woman that Yamino and Loki talk to say that her mistress-who died in a fire-used to always carry around a doll. (specifically, the doll that Mayura found). she claims the doll never left the mistress's sight. However, if the mistress [who remains unnamed] died in a fire, then shouldn't the doll have burn marks, at least? And what was it doing in the clock tower, if it never left the girl's sight?
