I feel like the lady who shares similar looks/smells is actually a shape/shifter and is most likely masking their scent based off the girl... i have a feeling next chapter the lady is going to reveal herself as some grotesque monster shes been hiding something for 3 solid chapters now and they both know the scent is weird i have a feeling shiori saying that she knew she was listening to the conversation hence why she left abruptly.. either way i cant wait to see what happens its gonna be so good
