Doctor examines Romana’s spider venom origin

The Doctor and Adric confront Romana’s mysterious coma following her exposure to spider bites. He rules out a simple toxin, suspecting a psychochemical agent from the marsh creatures. Recognizing the need for microscopic analysis to understand the venom’s alien origin, the Doctor shifts focus from their failed search for K9’s severed head to an immediate investigation in the science unit. Romana’s debilitation forces them into unraveling the deeper interstellar conspiracies masked within the Starliner’s fragile ecosystem. key_dialogue: [ DOCTOR: She's still alive. Some kind of coma. Did you find K9's head?

After: Determined not to be in the cave, eliminating that line of inquiry
Spider Tissue Sample

Spider tissue from Romana’s wounds is identified as the critical sample requiring analysis. The Doctor determines it contains a psychochemical agent rather than a simple toxin, making this microscopic evidence central to diagnosing and treating her coma.

Before: Biological contaminant on Romana’s skin, source of coma …
After: Identified as alien psychochemical venom meriting microscopic investigation
