Alien parasites cause hallucinations to various members of the Destiny crew. The situation gets out of hand when the parasites jump to new hosts.
- Freak Out! a corporal starts shooting up the mess after hallucinating "snakes under the skin". Rush hallucinates the blue aliens invading the ship, and attacks Wray and Greer thinking they are blue aliens.
- Through the Eyes of Madness we see various characters hallucinations as they interact with them. Lt. Scott and Chloe have sad hallucinations, but James thinks she's committed murder, Greer thinks he's dealing with another mutiny, and Rush sees the blue aliens invading the ship.
