Why This Matters Across Episodes
The longer arc this connection carries
Both events involve the group uncovering sinister scientific or technological artifacts (DN6 insecticide, helmet communication device) that reveal the depth of human vulnerability and the fragility of civilization. Barbara and the Doctor’s analytical response to these discoveries ('We must get her back to the ship' vs. 'He was murdered!') mirrors their roles in confronting systemic threats.
