Question: Did Diane Farr sign on to Numbers before or after she shot the season finale of Rescue Me? I guess what I'm asking is, will she be written out in the Sept. 13 season finale or will her exit be explained in the beginning of the third season?

Answer: Farr's story line will be wrapped up in the finale. "I told them at Episode 8 [that I was leaving], so they had five episodes to finish the arc of my character," she says, adding that, "The whole relationship [between Laura and Franco] is laying the groundwork for my exit."
