This guy's ulcer is giving Brimley an ulcer! In this exclusive clip from this week's episode of The Blacklist, Teddy Brimley (Teddy Coluca), Red's (James Spader) malady-prone go-to guy when he needs to do "enhanced interrogation," didn't account for the source's own medical issues while torturing him, and now they have a body to get rid of and no information. Dang. Tough break for poor Walter Higgins.

The clip also introduces Laura Sohn as Agent Alina Park, a young FBI agent Liz Keen (Megan Boone) is taking under her wing. Welcome to the Task Force, Agent Park! This is your life now! She'll be guest-starring for the next few episodes.
