Why This Matters Across Episodes
The longer arc this connection carries
By prioritizing human revival under threat in Part 3, Vira sets off a chain of escalation (Wirrn growth, pupation) that requires desperate countermeasures. This crisis logic necessitates Sarah’s perilous journey through the transport ship conduits in Part 4, as the plan to electrify the chamber demands outside intervention.
