Why These Connect
The narrative assertion
"The discovery of the slime trail (evidence of an alien organism) drives the Doctor's deduction that the station is more than mechanical — it's biogenic. This realization directly leads them to search for Sarah, believing she was taken by an organism, not just machinery."
