Exclusive: Fox's The Finder Recruits Chuck Badass, Teen Newcomer

Mercedes Masöhn, a onetime member of Chuck‘s deadly-sexy C.A.T. Squad, will continue to exact justice — on the Fox midseason series The Finder, TVLine has learned exclusively.

Also joining the cast of the Bones offshoot is 16-year-old newcomer Maddie Hasson.

Masöhn has landed the series regular role of Isabel Zambada, a Deputy U.S. Marshal who enjoys a “vigorous friends with benefits” relationship with “Finder” Walter Sherman (played October Road‘s Geoff Stults). The romantic wrinkle: Forever wooed by the FBI and with her eye on one day becoming the first female Hispanic Attorney General of the United States, Isabel knows that Walter’s brazen, corner-cutting P.I. tactics could prove to be a liability to her career path.

In addition to her appearances as Chuck‘s “Zondra, the bitch,” Masöhn’s credits also include CBS’ short-lived Three Rivers. (Fun fact that a peer just noted: Mini Anden, who on Chuck played Carina aka another member of the elite C.A.T. Squad, guested on the Finder pilot.)

Hasson, meanwhile, will fill the series regular role of Willa, a “manipulative, cynical and extremely bright” girl born into a family criminals, where she learned way more than a thing or two. Currently out on parole (!), the teen is committed to help out Walter and Leo (Michael Clarke Duncan) at the Ends of the Earth bar, while more often than not also lending her scrappy, con girl skills to their investigations.

The two cast additions fill the void left by Saffron Burrows (Deep Blue Sea), who appeared in this spring’s backdoor pilot episode of Bones, but is not continuing with the series.
