Don (Rob Morrow) and Charlie (David Krumholtz) find themselves in conflict over their differing beliefs in this week's emotionally charged season finale of Numb3rs, screening on Sunday, May 24th at 9:30pm on 3.

This week fans will not only have to say goodbye to the fourth season of Numb3rs, but will also bid farewell to yet another cast member.

After Sabrina Lloyd left the series in the first season, Diane Farr stepped in to fill the void as FBI agent and psychological profiler Megan Reeves. But after three years on the forensics drama Farr has opted not to renew her contract.

This week's season ender titled "When Worlds Collide," will see Megan face a crisis of conscience and leave the team to pursue another occupation.

"I think after three years, most actors feel the need to see what else they can use their brain for," Farr tells American TV Guide of why she decided to leave the popular forensics series.

However fans will just have to stay tuned to find out how this will pan out. Meanwhile, Farr reveals her reason for leaving Numb3rs has nothing to do with creative differences or the fact that she recently gave birth to twins.

"I'm not leaving because I'm having babies. I'm leaving because I'm going to do a different job," she explains.

And while the actress is looking forward to her new projects she still acknowledges the fact that her Numb3rs stint was great experience.

"Numb3rs was such a perfect job. It was easy and it was fun and it was good people," she says, remembering her most memorable moment as "when Megan was trying to seduce Larry, it was really fun because Peter MacNicol was very afraid of the love story."

Make sure not to miss Diane Farr's final ever Numb3rs episode when the series concludes its fourth season on Sunday, May 24th at 9:30pm on 3.
