Solitary

S1, E11: With Beta and Gamma sounding an unearthly duet between the Antares and Venus, the crew confronts loneliness and isolation – each in their own way. In flashbacks to the Ascan training process, Rollie helps Jen overcome her fear of the sensory deprivation tank, while the normally composed Nadia fights her own issues with the isolation experience. Donner tries desperately to perfect the planetary landing, driven by his terror of repeating the Mars disaster and the fear of losing Zoe. Nadia finally comes face to face with her hallucination, the resulting shock finally cracking her icy composure and sending her to Donner for comfort.
