Lisa Edelstein continues to make the rounds on the small screen. Her latest stop: ABC's Castle. Edelstein's character, the tough and highly skilled federal investigator Rachel McCord, plays a crucial role in determining the future of NYPD detective Kate Beckett (Stana Katic) and crime novelist Richard Castle (Nathan Fillion). In the season-five finale, Beckett was toying with relocating to Washington, D.C., to work on a task force at the U.S. attorney general's office, a dilemma complicated by Castle's proposal of marriage.
