Hernandez will play a cop on the series, and the site speculates that she will be working in Miami Metro's homicide department. While it wasn't said how many episodes of the upcoming fifth season Hernandez would appear in, the site did also speculate that this was the last of the new recurring roles for this new season.
Hernandez joins new casting additions such as Julia Stiles, who will play a potential love interest, Maria Doyle Kennedy, who will play the new nanny to care for Dexter's son, and Shawn Hatosy, who will play "a bad guy," according to an earlier report. It was previously speculated that Hatosy was playing a new FBI agent.
