The Enemy Within

Plot: The personnel of the SGC must fight to save Major Kawalsky's life after it is discovered that he has been infested by a Goa'uld.

An important part of this episodes is the establishment of Earth as the home of the people of the Tau'ri, the birthplace of humans within the galaxy. The advancement of the people of Earth may be the galaxy's only hope for freedom from the Goa'uld, who hold power over hundreds of planets, maybe more.


While the fate of Major Kawalsky is met with unfortunate consequences, the episode facilitates Teal'c proving himself to the higher ups in Washington and Langley, allowing him to join SG-1.

There is no gate travel during this episode, which creates something of an anti-climax following the excitement of the pilot episode. Still, good seasons are built on solid foundations (see Heroes season 2) and this episode really helps to add intriguing levels of depth to the Stargate universe.
