Dexter manipulates Migual into believing that Ramon can't be trusted with the secret.  Rita declines Dexter's proposal initially but accepts it in the end.

Shopping at a grocery store with Rita, Dexter becomes suspicious of a stranger talking to Astor; he proceeds to check the guy's background and finds out that his name's Nathan Martin, a pedophile recently released from prison. Dexter

sneaks in Nathan's house, but doesn't kill him. Debra finds a new victim, who is killed the same way as the previous Jane Doe, and assumes Freebo is the killer. Miguel attempts to bond with Dexter, but Dexter is unsure whether he is sincere.

The fact that Rita is pregnant distracts Dexter from his work. Through Freebo's victim, Dexter finds out where Freebo is hiding. He prepares the ritual before stabbing Freebo in the neck. Also aware of Freebo's whereabouts, Migual, carrying a gun, is on his way to killing him, too. Dexter encounters Migual, making him believe that he kills Freebo in self-defence. Migual hugs and thanks him for avenge his brother's death.

On his way to finish Freebo, Dexter stabs a stranger in the chest after being attacked. He panics since he has never killed someone who isn't a confirmed criminal, and this also breaks Harry code. Miguel Prado, the victim's brother and a powerful prosecutor, claims that his brother died a hero, but Dexter doubts it, and the story begins.
