S1·E20 Diseased

Hobbes and Darien meet with one of Hobbes' contacts to set a trap for their arch-enemy, Arnaud. Arnaud manages to escape Darien with the aid of a smoke canister, which turns out to contain a biological weapon. Darien is soon displaying flu-like illness symptoms, and is excreting black, contaminated Quicksilver. The Official and the Keeper send him to a military hospital...which Arnaud has already infiltrated. He plans to remove the Quicksilver Gland from Darien's skull via surgery, but the illness complicates matters. He must kidnap the Keeper to cure Darien so he can gain an uninfected Gland. Darien manages to escape and, overwhelmed by madness, almost kills Arnaud. The Keeper manages to stop him but Arnaud escapes. (Copyright 2002 Steve Crow)
