In Episode 15 of Season 4 of The Blacklist, Reddington awakens in a hospital bed and discovers that he has been poisoned and may only have hours to live. Dembe is nowhere to be found. Reddington believes that one of his 11 closest associates betrayed him. Reddington believes that the Apothecary is the only person who could have concocted the lethal agent and he asks the task force for their help finding him. Liz and Ressler try to find the Apothecary while Reddington retraces his steps alone, trying to reconstruct the events of the previous night. Reddington is fading in and out of consciousness but he learns that his attorney Marvin Gerard did not appear at the meeting of his associates and that Marvin was leaving the country. A wine bottle sent by Marvin appears to be the method of poisoning. The task force finds the Apothecary and convinces him to provide the antidote to spare him the death penalty. Reddington is cured but the Apothecary doesn’t know who hired him. Liz reveals that the laboratory testing showed that the poison was not in the wine, but in his scotch. Dembe is now the prime suspect.1
