Spoiler warning: Spoilers for the complete 2026 limited series; discussion of addiction and sexual violence.
Ingrid killed Aaron to protect Paige, unaware that he was also her own son. Run Away answers where the missing daughter has been, then makes the mother’s hidden history the final threat to the reunited family.
Is Paige alive?
Yes. She has been in rehabilitation arranged with Ingrid’s help. Simon’s search has therefore been taking place alongside information his wife and daughter have not shared with him.
The revelation does not make his fear unreal. It shows how the family’s attempts to protect one another have also kept them from understanding the same situation.
Paige returns to treatment after seeing Ingrid in hospital. Finding her is a crucial step, but it is not the completion of recovery or a guarantee that the family can simply resume its earlier life.
Why do the cult killings not explain Aaron’s death?
The cult’s agents target male heirs whose existence threatens the division of its leader’s property. Aaron is among those intended victims, but Ash and Dee Dee find him already dead.
Ingrid has acted separately, after Aaron’s abuse and interference with Paige’s attempt to stop using drugs. The wider murder campaign makes a convenient explanation available to investigators without making that explanation correct for him.
Two motives converge on the same man. Keeping them separate is necessary to understand why solving the cult case does not solve the family’s remaining secret.
How is Aaron related to Paige?
They share Ingrid as their mother. During her time in the cult, Ingrid was told her first baby had died; he had instead been placed for adoption. Aaron’s connection with Paige came through genealogy, not a romance between strangers.
Simon pieces that history together after learning Ingrid committed the killing. Paige asks him not to reveal the full truth to her mother.
The final dinner leaves the choice hanging over their apparent togetherness. Ingrid can believe she has confessed everything while Simon and Paige know something she does not. Protecting her from that knowledge would also make their rebuilt family depend on another silence, repeating the method through which earlier attempts at protection became so damaging.
