Martin Whitly (Michael Sheen): The Surgeon

[Driad]

What makes Martin tick?  What makes him kill?  What makes him smile?
Spoiler tags are not needed for episodes that have aired (U.S. eastern time).

I just want to go on record as saying that I ADORE any role that Michael Sheen plays.  And he is DELICIOUSLY diabolical as "The Surgeon."

From IMDb page: “Claremont Psychiatric Hospital is fictional. Its exterior shots belong to the Findlay Teller Apartments in the Bronx, New York City.”
