Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Autons created during the Nestene invasion in Episode 704 remain dormant on Earth after the Nestene brain is destroyed. The Master later discovers and reactivates one of these Autons, directly exploiting the leftover alien technology."

Why This Matters Across Episodes
The longer arc this connection carries
The existence of Autons as physical agents on Earth originates from the earlier invasion; their re-use by the Master demonstrates the persistence of alien threats beyond a single defeat.
