As part of the plan to fill the void left by Diane Farr's departure, Sophina Brown - who most recently was part of the Shark ensemble - is joining CBS' Numbers this fall.

Brown will play Nikki Donat, a former LAPD officer and adrenaline junkie who joins Don's FBI team as a junior agent. Brown's gig is recurring, says the Reporter, with the potential of becoming regular. - Matt Mitovich
