Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Romana's demonstration of expertise in reassembling the Key of Time fragment (Episode 9) establishes her competence and independence, which later creates tension when she goes missing in Episode 10. The Doctor's reliance on her abilities foreshadows his desperate search for her."

Why This Matters Across Episodes
The longer arc this connection carries
Romana’s unexpected skill in the TARDIS directly contrasts with her sudden disappearance in Part 2. This sets up the Doctor’s urgency and emotional vulnerability in searching for her, linking her competence (Episode 9) to her peril (Episode 10).
