 Rita later tells Dexter that he provoked a fight shortly thereafter with another inmate, who beat him to death with a pipe.In the book series, Rita's ex-husband is mentioned but never makes an appearance (or is named) since he is dead before the events of the books.In the TV series, by contrast, Paul appears in the second half of the first season and in the first episode of the second season, and his interactions with Dexter lead to a key plot point.
