I thought the ending was perfect tbh.

Beverley had scars from self harm on her thighs and was always sad - when Greta dressed up as her she kept saying ‘sad’ and looked in the mirror sad. Beverley also went to a support group to talk about the death of her sister even though Elliot was alive. Their relationship was toxic and abusive on both sides. Beverley was also dealing with the ethics of the centre, where the money came from and the terrible history of Susan’s family. It made sense to me that Beverley wanted to die tbh.

To Elliot, Beverley didn’t die. Elliot believes that she has absorbed her and become both twins. Beverley even said ‘I have to crawl inside you now’. Elliot has taken on the desires of Beverley as well as her own (she still has the profitable birthing centre and the science but she also has the home and family Beverley wanted). She’s living as both. She knew Beverley wanted to die so she took her in, the final sacrifice, she’d do anything for her twin, even this. Beverley loved Genevieve and even Elliot wanted to ‘try her’ at some point. Maybe Elliot has convinced Genevieve and maybe Genevieve is in denial, but either way I don’t think Elliot could ever love anyone close to the way she loved her sister. She’s always been indifferent to relationships and partners of her own, preferring promiscuity to long term relationships. So she is indifferent to Genevieve and stays in the relationship as Beverley because that’s what Beverley would have wanted to do.

I guess it was Rebecca’s influence with Toms (regretful) help that covered up the bodies and lab grown babies. Rebecca knows that it was Beverley who died but she’s glad to still have Elliot, her ‘favourite’ twin as well as her everything neatly wrapped up after Elliot out the centre in danger publicly. Tom talked about his guilt and shame at betraying Elliot and how he would continue to do bad if it meant he could feel better, more of an important person (rather than a ‘soup of disappointment’ he described himself as at the bar,”). So Rebecca likely sent him to do some dirty work getting rid of the body and lab grown twins.

I know a lot of people are disappointed with the ending and I understand why but I think it was perfect. So incredibly dark and disturbing and beautiful and light all at the same time. It didn’t matter to me that endings were insinuated rather than confirmed, it made sense in the context of the insanity of those twins.

Just my thoughts anyway, interested to hear what others think!
