The Conflict - S3-E1
Other mistake: While Martha Corinne is standing in front of the bathroom sink in the new house, we see her height compared to the mirrored medicine cabinet above the sink, and Martha Corinne is quite a bit shorter than the mirror's knob, even with her bonnet. When she reaches up to open the cabinet door, in the next closeup from behind her she is now taller than that knob. For this specific closeup The Actress was presumably standing on a stool, in order to have the perfect shot of her turning her head, then being surprised by her own reflection in the mirror.
