The Doctor's Knife

A compact, utilitarian blade with a dark handle, its edge worn from frequent use and honing. The Doctor employs it in the Starliner reception to probe the properties of the river fruit, twisting it slightly as he examines the specimen. When he turns away, an amphibian deftly removes it from his grip, demonstrating both the creature’s precognition and the planet’s covert threat level. The knife’s loss halts his investigation and marks the first physical confrontation with the amphibians’ territorial defiance.
