Mr. Kaplan’s (Susan Blommaert) war on her former employer and friend Raymond Reddington (James Spader) reaches a fever pitch in a two-hour The Blacklist season finale airing Thursday night.

Reeling from double blows from Kaplan and obsessed FBI investigator Julian Gale (Enrique Murciano), Reddington visits Liz Keen’s (Megan Boone) grandfather Dom (Brian Dennehy) to unearth something that he’s always said he would only do as a last resort. It seems this is exactly that.
