Mahershala Ali (The 4400) guest stars in the March 12 episode of FOX's Alcatraz as a man who was wrongly convicted back in the day, but is now seemingly doing bad things in the present. The episode will undoubtedly answer the question about "why" he had a change of behavior.
FOX has released six images from the episode, which is titled "Clarence Montgomery" after the escaped Alcatraz prisoner in question. The new images feature Mr. Ali, Jorge Garcia, Sarah Jones, and Sam Neill.
Note: This episode was originally scheduled for February 27; it will now air on March 12.
