The Enemy Within

01.03 Episode 3 (#3955)
Airdate: August 1, 1997

Earth faces threats on many fronts following SG-1's return from Chulak. Teal'c, the Jaffa who risked his life to rescue SG-1, is met with suspicion and interrogated by military intelligence. Meanwhile, Major Kawalsky has been taken as a host by a Goa'uld larva which is demanding to be returned through the Stargate. Kawalsky's only chance is surgery, and with Teal'c's guidance, the larva is removed, but not in time to prevent the Goa'uld's control of the host. In a final confrontation, Kawalsky loses his life as Teal'c must prevent his return through the gate.
