Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Keeper's warning in Episode 21 about the 'all-pervading evil' (a concept also framed as something beyond Traken) resonates in Episode 26, where the TARDIS's Cloister Bell—a signal of doom—tolls again, this time due to the Master's interference, echoing the Doctor's need to address a pervasive threat."

Why This Matters Across Episodes
The longer arc this connection carries
The recurring motif of a 'presence' or 'evil' that the Doctor must confront links Episodes 21 and 26. The Keeper's warning about an abstract evil on Traken parallels the TARDIS's mechanical and existential instability in Episode 26, reinforcing the Doctor's role as a guardian against unseen, creeping corruption.
