"Scott: She’s the one who keeps looking at her watch and tries to ensure that the house is all respectable and well-oiled. A bit annoying, but she dies and everyone misses her.
Robin: The guy who was wearing a suit before, who looked like he wasn’t used to wearing a suit and is a really nice guy [Tom]? That’s her illegitimate child. He doesn’t know, but she knows, and she’s got a job in this house to watch over him. And then one day, it will be revealed.
Richard: Maybe that’s [Bates’] sister, actually. She’s taken on the duties after he went to prison.
Tom: That’s the housekeeper. She also knows all of their secrets. Unlike [Carson], she may disapprove of them somewhat, but she’s more concerned about their lives, tries to keep the peace. She quietly works behind the scenes to try to smooth over all the drama whilst struggling with her own internal dilemmas about being a lesbian.”
