Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Arbitan's warning to the Doctor ('If when you return, you find the Voord have taken this building, do not let them get the keys. You understand? Destroy them!') foreshadows Barbara's desperate struggle to destroy Morphoton's influence when she alone sees the city's decay."

Why This Matters Across Episodes
The longer arc this connection carries
Both events involve a companion (Barbara) being the sole resister to corruption or control, with Arbitan's ominous command echoing her later fight against Morphos' illusions.
