Sarah's frustration boils over in the conduit

Sarah’s panic and exhaustion surge as she physically struggles in the cramped conduit, her desperation breaking through Harry’s hollow attempts at distraction. His forced humor highlights their widening disconnect—her genuine fear versus his refusal to confront the stakes. This moment cracks the surface of their partnership, exposing how their divergent coping mechanisms could undermine the mission when every second counts. The pressure of the Wirrn’s invasion and the life-or-death stakes amplify the fracture, forcing Sarah to question whether his comfort is enough or if she must face the conduit alone. key_dialogue: [ SARAH: I keep getting stuck! HARRY: (OC) Marvellous thing about old Sarah. Terrific sense of humour. ]
