Episode 4.06: Nocturne
Airdate: February 9, 2005

It’s Dawn of the Syd after Ms. Bristow is bitten by a crazed operative infected with an experimental drug, which is slowly driving Syd out of her mind. And has her out for blood once Vaughn and Jack move in to stop her from killing everyone around her. Meanwhile, Dixon lets Sloane in on plans for bringing him down.

Sydney becomes infected with a mind-altering and potentially deadly hallucinogen, causing her to slowly lose touch with reality. Vaughn and Jack must scramble to find an antidote before Sydney’s hallucinations, paranoia and resultant violent behaviour threaten her life and the lives of those around her.
