Dr. Bill Thompson was assigned to the scientific team on the moon of a gas giant, designated as M4C-862. He was very excited about the discovery of the Small energy being which inhabited the moon, but, unfortunately, the lifeforms swarmed against him and began attacking him with vicious intent. Initially their behavior had been peaceful and curious, but due to reasons unknown to the Stargate Command personnel, they turned angry and dangerous.
But the beings had turned against Thompson, stinging him and causing him great pain. Dr. Bill Lee who had accompanied Thompson managed to get back to the research facility and call for help. While Major Samantha Carter was tasked with keeping the scientists inside, Colonel Jack O'Neill and Teal'c raced to the clearing area where they found Thompson lying on the ground. Unfortunately, it was too late as Thompson was already dead. (SG1: "Prodigy")
