I am happy to spoil that when Castle returns in the new year, another Browncoat will be guest starring along side fellow Firefly alum Nathan Fillion. Gina Torres has been cast for the 14th episode, reports TVLine. Torres' character, Samantha Foster, is a devious fashion mogul who stars on a "Real Housewives"- type reality show. As always, I'm sure we look forward to many Browncoat Easter eggs when Captain Mal reunites with his second in command. Gina currently plays the a managing partner of a high-powered law firm on Suits.
