Hannah is still wearing the same clothes as when Sean had first met/summoned her. For the most part anyway. Draped over her shoulders is a
short, old-fashioned coat that looks incredibly dated. Try as he might, Sean can't really figure out when she put this on, much less how or where she got it from. Hannah meanwhile doesn't seem to acknowledge it either and for all Sean can tell it just kind of appeared on her.
"I don't recognize it, but it
feels familiar. If that makes any sense..." she says, looking out over the woods.
