The team, now designated SG-1 are planning their next foray through the gate as they try to map out the variety of sites available to them and locate their missing friends. O'Neill asks that Teal'c be allowed to join his team but Gen. Hammond thinks that will be unlikely given that he is the host for a Goa'uld. Unknown to anyone, however, is that O'Neill's close friend, Maj. Charles Kawalsky, leader of SG-2, has been infected by a Goa'uld, an immature version that has not yet taken complete control of the host. Kawalsky is having regular blackouts during which the Goa'uld is trying to return to the gate. An MRI reveals what is wrong but it's unlikely the creature that has fused itself to Kawalsky's spine can be surgically removed. Meanwhile, Col. Kennedy arrives to question Teal'c who has pledged his loyalty to his new world. Written by garykmcd

A Step Up from the Pilot
31 March 2017 | by George WoodSee all my reviews

This was another good episode, and a direct continuation from where the pilot left off. Although this episode is much more small-scale and mainly focuses on Kawalsky, I thought it was better than the pilot because it was more focused, and continued to develop the main characters. It is tense and exciting throughout, and there are some really sad moments. Aside from Kawalsky, I liked the continuation of the Teal'c story line, and of what would happen to him. The ending is very emotional and satisfying, but well deserved, and there is a very good line said by O'Neill that will stick with me. Overall, a step up from the pilot, and one that leaves me excited for what is ahead.
