Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s mental colonization in the duplication chamber in Episode 13 directly causes his later vulnerability and reliance on Stien in Episode 14, which in turn enables Tegan and the group to reclaim the TARDIS."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor’s suffering in Episode 13 forces a bond with Stien in Episode 14, which allows the companions (including Tegan) to secure the Duplication Room and progress toward liberation. Tegan’s presence in both events ties her arc to the Doctor’s fate.
