Majorino will play Special Agent Genny Shaw, who, as we previously reported, will assist Booth (David Boreanaz) in his search for vigilante sniper Jacob Broadsky (Arnold Vosloo). Agent Shaw's inexperience, however, will quickly become apparent when her cover is blown by Broadsky during a stakeout. Ultimately, her mistake will put both her and Booth in Broadsky's crosshairs.

Besides her work as Mac on Veronica Mars and her recurring role as Heather Tuttle on Big Love, Majorino is best known for playing Deb in Napoleon Dynamite.  She most recently starred on ABC's short-lived legal drama, The Deep End and guest-starred on the soap opera-themed episode of Castle.
