In The Blacklist episode ‘Gaia’, while Red (James Spader), Liz (Megan Boone), and the task force try to track down eco-terrorist Gaia (Louis Cancelmi) who has mysterious ties to Alexander Kirk, they meet Dr. Sebastian Reifler. It seems Red has Dr. Reifler right where he wants him — but this isn’t the last time we see Reifler.
Dr. Sebastian Reifler is portrayed by Matt Servitto. He’s known for his roles on Banshee (Sheriff Brock Lotus), Harry’s Law with Kathy Bates (Judge Lucas Kirkland), Law & Order (U.S. Attorney Horvath), Brotherhood (Representative Donatello), The Sopranos (Agent Dwight Harris), and All My Children (Trask Bodine), among others. The Blacklist airs Thursdays at 10pm on NBC.
