At the end of the tenth season of CSI, Langston was stabbed and left for dead by serial killer Nathan Haskell (Bill Irwin). At the Television Critics Association press tour, Robert David Hall revealed that his character, Dr Al Robbins, will share an emotional scene with Langston when he visits the wounded CSI in the hospital. Meanwhile, Haskell will be back for the premiere, and he’ll also appear in three more episodes during the season that lead into the introduction of Langston’s wife. “Toward the end of the season, Mrs. Langston will play a pivotal role,” explained showrunner Carol Mendelsohn.
