Doctor defies quarantine protocol

The Doctor challenges Stevenson’s plan to execute a plague-infected crew member, asserting medical authority over institutional panic. Stephanie and Lester defend quarantine with grim efficiency, while Kellman escalates rhetoric by labeling the Doctor’s companions as contagious threats. Sarah dismantles accusations with logic, exposing the tenuous foundations of the quarantine doctrine. Reluctantly convinced, Stevenson permits an examination but removes it from the vulnerable control hub. The exchange forces Stevenson to confront the logic of his own restrictions amid rapid escalation of the station’s mortal crisis and the lurking presence of traitors manipulating fear.
