Why This Matters Across Episodes
The longer arc this connection carries
Romana’s identification of the dwarf star alloy in the Great Hall (E19) directly informs her realization in E20 that the ship’s hull could trigger a 'huge mass' capable of distorting time and space. This causal link bridges her growing expertise and the Doctor’s reliance on her analytical skills.
