Rita and Dexter then go to a marriage counselor, who allows them to sort out their problems and instigates peace between them.
However, their neighbor, Elliot, begins to fall for Rita, kissing her and pointing out that Dexter is never home.
Dexter is a forensics expert and blood spatter analyst employed by the Miami Metro Police Department, but has a double life as a vigilante serial killer.
As young boys, he and his older brother Brian witnessed the murder of their mother, Laura Moser, and were left for two days in a shipping container filled with blood. Soon afterwards, Dexter was adopted by Harry Morgan, who hoped to help repress his memory of the death of his mother.
Rita Bennett was Dexter's girlfriend and later wife.
Rita begins to notice a pattern of lies from Dexter, including deceiving her about the concussion he suffered in the car accident and the ownership of his old apartment.
Animals do not like Dexter, which can cause noise problems when Dexter stalks a victim with pets.
He is quoted as having once had a dog that barked and growled at Dexter until he was forced to get rid of it, and a turtle, which hid in its shell until it died of starvation rather than have to deal with Dexter.
These thoughts distract him while he is waiting for an intended victim, which thoroughly annoys him.
In the TV series, Dexter also takes a detour in his code of only killing murderers in order to dispose of a pedophile who is stalking Astor.
Rita tentatively starts a relationship with Dexter, while remaining unaware of his extra-curricular activities.
