Towards the end of Gillian Flynn's book, which makes its last turn a little longer than the series, Camille continues to meditate on Amma's motive. "Of course, you can make another 4000 assumptions about why Amma did that," she muses. "In the end, the fact remains: Amma enjoyed being hurt. I like violence she shouted at me." Finally, Camille concludes, "I blame my mother, a child who has been weaned from poison regards harm as consolation.
But after hearing Adora's story about the abuse she suffered through her own mother, it seems certain that the guilt in the branches of that particular pedigree is high
Camilla's sacrifice to save Amma and find out once and for all whether Adora is poisoning her children is heroic. It is also the ultimate expression of the particular illness she grew up in Crellin's household – and Wind Gap, a city whose violent, sadomasochistic tendencies were influenced by Adora's ancestors, the Calhouns. Instead of playing her mother's game by cutting into her own skin, Camille became both the attacker and the victim, both Adora and Marian. Unlike Amma, however, she repeatedly took away her aggression against herself.
Camille certainly has more in common with her mother and sisters than she would like, and though she may not share anything of Alan's DNA, she seems to share some of his denial. On Adora's ivory floor, she fights for her life. She has a strange vision that I believe is a flashback: There she is with Marian as a child on the same floor. It is a room she was only allowed to go into while ill and cared for by Adora. And just before the vision ends, Camille's eyes widen. At that moment, I think Camille remembers something that blocked her. Has not she always suspected that her mother caused Marian's death?
I imagine many viewers will be disappointed with this ending. If you asked, "Where is the murder mystery?", You could argue that you guessed this result weeks ago. But that's what I love about "Sharp Objects" and what makes it more resonant than so many other thrillers: it's a story about a woman who finally sees the scars of the trauma she endures in her family and in the city had to mirror this family.
