Jay Ryan joined the series in the second lead role, Vincent Keller (the character was originally called Vincent Koslow, though in the original series, Vincent had no last name). Max Brown signed on for the role of Dr. Evan Marks, a medical examiner who has feelings for Catherine. Brian White was the last actor to sign onto the series. White joined in the role of Joe Bishop, Catherine and Tess' commanding officer at the NYPD, who becomes romantically involved with Tess.
