S2E4 Crackers Don't Matter

The crew arrives back from a Commerce Planet, bringing along a timid alien named Traltixx and a stash of Crackers. Traltixx claims he can modify Moya's electromagnetic signature to render her invisible to detection. Crichton is doubtful, sensing that it sounds too convenient. While navigating a cluster of pulsars, the crew begins to succumb to an overwhelming paranoia, leading to violent confrontations among themselves. Crichton must confront his own irrational fears to uncover Traltixx's true intentions and find a way to thwart him.
