Rita (Bennett) Morgan
Rita Bennett (then later on Rita Morgan) is Dexter’s girlfriend and eventual wife, who plays a vital role in the hit television series Dexter on HBO. She is portrayed by actress Julie Benz, and is a loving and warm character on the show.
Quick Bio from Wikia:
Dexter Morgan’s “significant other”. She has two children (from a previous relationship), Astor and Cody Bennett and much later in the series, a third child named Harrison.
Rita often plays the role of a concerned mother who comes from a damaged relationship and, like Debra Morgan, she has her own story-line which progresses along with the main course of the plot. While she tended in the first season to be naively unaware of Dexter’s flaws, a complicated situation involving Lila West, after which she and Dexter grew apart and eventually reconnected, changed the fundamental nature of their relationship; where she had previously paid his long absences and flimsy cover stories no mind, Rita began to pick up on Dexter’s lies and occasionally questioned his erratic behavior. Ultimately, however, Dexter’s attachment to Rita and Rita’s devotion to Dexter continued to grow throughout their relationship and eventual marriage.
