Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Master's taunting of the Doctor in Castrovalva as the Portreeve (a disguise used to manipulate and trap Adric) echoes the Doctor's later vulnerability to the Terileptils' powerpacks in The Visitation. Both episodes feature the Doctor's companions being compromised by external devices under the antagonist's control, mirroring the Master's earlier psychological and spatial manipulation."

Why This Matters Across Episodes
The longer arc this connection carries
The Master's 'powerpack' via the tapestry and the Terileptils' powerpacks represent two distinct but thematically similar tools of domination—the former through temporal-spatial distortion and the latter through direct mind control. The Doctor's recurring role as the one targeted by these devices ties the two antagonists' schemes to the same conflict arc of the Doctor versus external domination.
