A ghoulish hitman uses a laser to blind any witnesses to his killings. Fawkes and Hobbes trace him to a blind model who the killer is romantically involved in, but the assassin escapes, blinding Fawkes in the process. Since he was turning invisible when the laser hit him, the effects are temporary, and he can still see if he covers his eyes with the quicksilver formula. Unfortunately, that aggravates his growing insanity. The blind model helps him to deal with his blindness, and the two become romantically involved. Fawkes figures out that the assassin's most recent victim was merely a lure to get his real victim to the man's funeral. Fawkes, overwhelmed by Quicksilver Madness, throws the assassin to his death.

Allianora (from ""Ghost of a Chance""), the Woman in Black, contacts Darien and invites him to join the Organization (i.e., Chrysalis). He is understandably reluctant, but she shows him top secret Agency files that show they are planning to replace him with a more cooperative Gland recipient. He investigates and finds the information to be true, but also discovers that the plan was for him to be the replacement for his predecessor. Remaining loyal to the Agency, Darien attempts to infiltrate Chryalis, and even takes up their offer to ""kill"" Allianora, suspecting the bullets are blanks. They are, but she is wary of him once he ""proves"" he is willing to kill her. Darien then tries to infiltrate Chrysalis' computer banks, but is caught. Before they can remove the gland, Allianora frees him, setting the HQ building on fire. She disappears once more.

Thanks to a leak in Chrysalis, Hobbes and Darien get the goods on a politician that Allianora is trying to bribe. Realizing they have a leak, Chrysalis takes unspecified measures to stop the leak. Allianora visits Darien and tries to force him to give up the name of their contact, but he refuses and the two end having making (invisible) love. The next morning Bobby and Darien meet with the contact, only to have him killed by a Chrysalis ambush. The Keeper soon realizes that Darien was bugged with nanobots during his...encounter with Allianora. They transmit everything he sees and hears. The Official fake-executes Darien while they put an insulated helmet on him to make Chrysalis think he's dead. They then investigate a pharmaceutical firm and discover Chrysalis plans to attach the nanobot bugging devices to students at an elite school. While Hobbes and the Keeper stop them, Darien tries to lure off the Chrysalis strike team to the school pool. Using a pair of goggles, he prevents them

The Keeper is accidentally injected with an experimental serum that could cause her to become permanently insane unless she can be given an antidote in time.
