Louise Lombard Returning to CSI

Louise Lombard will return to CSI for one episode, TV Line reports.
The former series regular, who left in the eighth season, will reprise her role as Sofia Curtis during the CSIs' hunt for escaped serial killer Nate Haskell (Bill Irwin) in a May sweeps episode. Curtis, who's now a deputy chief, will meet Langston (Laurence Fishburne) for the first time, but they don't exactly get off on the right foot when she suggests calling in the feds after Haskell sightings in Mexico.

"Of course, Langston begs to differ. The episode is really about where is Nate Haskell," executive producer Carol Mendelsohn says. "Sofia actually blames Langston and Catherine [Marg Helgenberger] for Haskell's escape. And she blames Brass [Paul Guilfoyle]. ... [Brass then says] 'Hate to rain on your tirade, deputy chief, but we're not going catch Haskell debating ancient history.'"Though Lombard is currently attached for one episode, Mendelsohn teases, "You may see her in the finale, too."
