Why This Matters Across Episodes
The longer arc this connection carries
The Doctor’s acceptance of Katarina and his urgency to care for Steven after the Troy adventure sets up Katarina’s role in Episode 10, where her trust and naivety enable Vyon to infiltrate the TARDIS and manipulate the situation.
