Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Polly's liberation from WOTAN's brainwashing after the supercomputer's destruction directly enables her to be inside the TARDIS and travel with the Doctor, experiencing the revelation of its true nature."

Why This Matters Across Episodes
The longer arc this connection carries
Polly's arc from brainwashed pawn to freed individual is the fundamental cause of her presence in the TARDIS. Without the defeat of WOTAN in Episode 345, Polly would not have joined the Doctor's travels in Episode 401.
