Bennett reasserts control after Duggan’s breakdown

The oxygen rating readout is a small but vital detail in the departure procedure, confirming the safety of Laleham and Vallance’s mission. Vallance’s verification of the ‘green indicators’ is a fleeting moment of normalcy amid the chaos, but it also underscores the station’s reliance on technical checks to mask deeper failures. The object’s steady glow is a false reassurance, contrasting with the crew’s unraveling trust and Duggan’s despair.

Before: Functional and displaying safe oxygen levels, confirming the travel party’s readiness.
After: Unchanged, but its significance is overshadowed by the station’s collapsing cohesion.
