Why This Matters Across Episodes
The longer arc this connection carries
The fatal incident at Earth Control establishes the immediate threat (toxic substance/seed pods) and triggers the Doctor's analytical process, which ultimately exposes the broader invasion strategy. This escalates the conflict from isolated sabotage to a coordinated Martian attack.
