* NightmareFuel: IT has been sabotaging the cleaning suits for ''decades.'' Every person sent out to clean before Juliette could have survived, but IT deliberately swapped out the suit materials for faulty ones. The IT department is literally playing executioner.
* PrimalFear: Loads: claustrophobia AND agoraphobia, fear of the dark, sense-loss (by wearing thick blinded space-suits), asphyxiation (especially by choking on your own fumes).
* {{Squick}}: Solo's living conditions. For example, the toilets have stopped flushing in his Silo, so since Solo's the only one around, he just uses a bathroom until it gets disgusting before moving to another.
* TheWoobie: Solo, who is 50 years old and has been alone since he's been 16. Mentally, he's still a (smart, shy, kind) little kid.
