Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's instruction to K9 to compute a reverse transition and guard the TARDIS (Episode 13) is directly referenced in Episode 15 when K9's data access system is used to unlock Rassilon's tomb."

Why This Matters Across Episodes
The longer arc this connection carries
K9's role as the TARDIS guardian and his computational skills are established in Episode 13. In Episode 15, K9's ability to bypass security via a magnetic card system (a logical extension of his role) enables the Doctor to access Rassilon's archives, completing the arc of K9's utility in navigating their predicament.
