Why This Matters Across Episodes
The longer arc this connection carries
The TARDIS infection in Part 1 (cand_evt_scene_069b78db6d65e6c3_2) establishes a direct causal pathway to the Doctor's vulnerability in Part 2 (cand_evt_scene_734d082701d11cb3_1). The Nucleus's parasitic nature, introduced through Safran's actions, now targets the Doctor directly, elevating the threat from external invasion to personal mental warfare.
About Causal Connections
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.
