Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"In 'Snakedance,' the Doctor fears the Mara's awakening after centuries, a threat tied to Tegan's subconscious. In 'Terminus,' the Doctor faces the immediate threat of the Terminuses' raiders commandeering the TARDIS, a physical manifestation of external danger."

Why This Matters Across Episodes
The longer arc this connection carries
