lisa edelstein castle gi 'Castle' Season 6: Lisa Edelstein puts on a badgeFormer “House” star Lisa Edelstein will play an important role in “Castle’s” future in the coming season.

Edelstein will appear in several episodes of the ABC drama in the fall, TVLine reports. She’ll be playing a federal agent who could have a big say in Beckett’s (Stana Katic) professional future — and thus the future of the Beckett-Castle (Nathan Fillion) relationship.

You’ll recall that Season 5 ended with Beckett deciding to take a job with a federal task force in Washington — right before Castle proposed to her. Katic has said she knows the answer, and that it’s a “perfect one for the character and for the show,” whatever that may mean.

Whether, and how, Edelstein will influence that answer remains to be seen when “Castle” returns to its familiar Monday-night home in the fall (ABC hasn’t announced premiere dates yet).

Edelstein was most recently seen on another ABC series, “Scandal,” and also guested on “House of Lies” and “Elementary” last season.
