Why This Matters Across Episodes
The longer arc this connection carries
Kellman’s sabotage of the transmat system in Part 2 is the enabler for the Cybermen’s detection of the transmat beam, which triggers their boarding party and their refined plan to destroy Voga. This chain of cause (sabotage) and effect (Cybermen retaliation and countdown to destruction) directly leads to the peril Sarah and Harry face in Part 4.

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.
