Why This Matters Across Episodes
The longer arc this connection carries
After the Doctor integrates K9 into the Argo's systems in Ep 17 (cand_evt_scene_5abfc628e32caf0b_3), this intervention directly enables their survival maneuver during the crash-landing in Ep 18. K9 takes on a central navigational role, reflecting the Doctor's foresight in Ep 17 becoming the technical salvation in Ep 18.

A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
