Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Tegan's psychological trauma from Deva Loka (Mara possession) directly fuels her escalating frustration and vulnerability in the TARDIS (Episode 13), which manifests as open conflict with the Doctor. This tension persists into Episode 14's cellar escape, where Tegan's agitation and distrust likely intensify the group's dynamic."

Why This Matters Across Episodes
The longer arc this connection carries
Tegan's confession of the Mara's psychological violation to Nyssa in Episode 13 establishes her unstable mental state, which later contributes to her volatile reactions during the TARDIS argument and the cellar escape. The trauma is both a precursor and a complicating factor in the group's cohesion under pressure.
