Waiting for Jocko - S2.E4

Jocko, a man whom Dr. Hyatt recommended be remanded to a psychiatric facility for treatment at his parole hearing five years earlier, still holds a grudge, believing that Hyatt wanted him confined for life as a psychopath. On his birthday, Hyatt gets a surprise visit from Jocko, who holds him at gunpoint with the intention of forcing him to concoct nitro for deadly use.
