Rebecca Mitchell is a character in DEXTER. A girl cut off from the rest of the world at home, she is the daughter of Arthur Mitchell and Sally Mitchell while also being the younger sister to Jonah Mitchell. Because of the solitude forced on her by her father, she apparently lacks awareness of social norms, which leads her to inappropriately flirt with Dexter Morgan. Unfortunately she is just another victim in Arthur's madness, often referred to as "Vera Mitchell" rather than by her real name and treated so protectively just like Arthur wanted for his sister.
