Why This Matters Across Episodes
The longer arc this connection carries
Ian and the Doctor's immediate loss of Barbara during the Zarbi breach (Episode 17) creates the animus-driven conflict in Episode 18. The Doctor’s focus shifts from securing the TARDIS to locating Barbara, driving the negotiation with the Animus to extract her whereabouts. This is a direct cause-and-effect chain linking the two episodes.
