Why These Connect

Why This Matters Across Episodes
The longer arc this connection carries
Tegan's fear for their safety and desire to escape the corrupting yacht's atmosphere (E18) drives the Doctor's impulsive decision to accept Marriner's ominous invitation in E19. This escalates the physical danger of their situation and tests Tegan's loyalty to the Doctor's judgment.
