Summary
In The Enemy Within, it is discovered that Kawalsky has become possessed by a Goa'uld. The SGC must find a way to remove the parasite without killing him.

Kawalsky fought against being possessed by the Goa'uld, but eventually took complete control over him after an attempt by surgeons to remove the Goa'uld from him. The Goa'uld controlling Kawalsky escaped from the medical center where he is being restrained and activated the Stargate and tried to escape to Chulak, but Teal'c held him off. During this fight, the back half of Kawalsky's head was through the Stargate. It was then shut off, meaning that half of Kawalky's head was separated from his body, killing him and the Goa'uld inside him.
