Chloe is beautiful but has always been insecure. She has not moved on from Daniel and Kate knew just which buttons to push. If a person has PPD she has lost perspective and thus open to suggestion, graping ast sny reason to explain her feelings. That said, Chloe should know better than to accept Kate’s advice. Then again, her stongest ally Philip just told her that he didn’t believe her, chosing Melanie over her.
It ws kind of dumb having her fold laundry–if she has PPD, she wouldn’t care about that.
