Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's synchronization with the computer core in Episode 4 directly causes Tegan's distrust in Episode 10, as her questioning of his dismissal of the TARDIS's malfunctions ('pointing out the engines are failing') reflects lingering trauma from seeing him prioritize system overrides over safety."

Why This Matters Across Episodes
The longer arc this connection carries
This causal link underscores Tegan's internal conflict: witnessing the Doctor's self-sacrifice in Episode 4 makes his later dismissal of her warnings in Episode 10 a breaking point, fueling her disillusionment and driving her to assert her own judgment. It foreshadows her future agency in choosing her own path amid cosmic violence.
