Exclusive: Diane Farr's Numbers Up

Looks like Numbers will be minus its female star when it returns next fall.
Sources confirm to me exclusively that Diane Farr has opted not to renew her contract and will leave the CBS procedural later this season. Farr joined Numbers in 2005, filling the void left by Sabrina Lloyd. Prior to that, she spent two seasons lugging around heavy equipment and making goo-goo eyes at Daniel Sunjata on FX's Rescue Me.
There's no word on how her character, G-woman Megan Reeves, will be written out, or in which of this season's six remaining episodes she will last appear ( Numbers returns April 4). In what could be a clue, Megan's on-again/off-again romance with Peter MacNicol's Larry is expected to heat up as the season winds down. Perhaps they'll head off into the sunset together?
Producers, meanwhile, are already searching for Farr's replacement. On Monday, Numbers began casting the role of Nikki Donati, a 27- to 35-year-old ex-LAPD officer who joins the FBI in search of a "bigger and badder" challenge. She's described as a full-blown adrenaline junkie whose gritty street perspective makes her a great foil for her boss.
Now, help me out with this math problem: Farr Numbers = What? A sucky development? A fantastic opportunity to reenergize the show with some new blood? The worst thing to happen to Peter MacNicol since the final season of Ally McBeal? Crunch the Numbers and post the results below!
