Dexter is chasing Arthur and sees that he is stalking two siblings with their nanny and kidnaps the boy Scott Smith in an arcade by pretending to be a cop and telling Scott that his parents have been in an accident. Later, Dexter learns that there are several ten-year-old boys missing and they begin Trinity's cycle of four victims, not three as Lundy believed. Dexter meets Jonah, expecting to discover where his father might have gone and hold the boy captive. Dexter asks Jonah to help him by looking through his computer and desk for information to help him.
Dexter has to confront the real possibility that he may have more in common with Trinity than he'd like to admit. Secrets abound - from Cody, who is forced to defend one of Dexter's lies, Masuka, who can't bring himself to confess what he witnessed at Thanksgiving, and Debra, whose recent discoveries force one of Miami's finest into making an impossible decision.
Meanwhile Debra gives an interview to Christine and asks Angel to check the journalist's reaction when she asks how she could have been so fast to arrive at the crime scene. Angel sends samples of Christine's DNA from a toothbrush given to Debra by Quinn to Masuka and after the DNA analysis, they find that Christine and Trinity are relatives and Christine is arrested.
