THE RETURN OF JARED HARRIS!
Jared Harris played David Robert Jones a major villain in season one. He was a vicious killer, and enjoyed playing mind games with the stars of the show. Jared's character died in the finale, when he went to teleport into an alternate univese, but was stopped by Peter (Joshua Jackson). He stopped him with a device called a "plug" that could close the portal. It closed as Jones was halfway through, slicing him in half.
