Theory so far
working theory at the moment:
camboy Trevor works for his killer as a con for a company that extorts women going through divorces.
Trevor, then with his friends decided to do a side hustle to also extort money from clients. Trevor’s killer runs a company that relies on men going through divorces to hire them to extort the wives so the men can get full custody.
My theory is that Paula’s ex-husband/new wife hired this company to extort Paula to gain full custody. while Trevor wasn’t supposed to die, Trevor only got killed because he was using the same clients for his side scam and his employer/pimp views this as stealing money.
