Culture Shock! (comic story)

Summary
As the Doctor sits on a beach and ponders his rootless life, he hears a telepathic cry for help from what appears to be a small mammal. In fact the animal is only a host for a sentient cell culture, which is under attack from a virus. The Doctor injects the animal with a cure, and carries it to the ocean, where the culture can achieve its full potential. Touched by the culture's boundless gratitude for its saviour, the Doctor returns to the TARDIS and resumes his journeys.
