The team, now designated SG-1 (there will be nine exploration teams in all) are planning their next foray through the gate as they try 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. Unbeknown 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
Did You Know?
There is a scene in which Kawalsky is given a medical scan with his head inside a large ring device - approximately 6ft x 6ft x 2ft. This device is a real medical tomographic device manufactured in the early 1990s in Knoxville TN, USA. This device is a PET (positron emission tomography) medical imaging device - likely a model 953. As the radioisotope undergoes positron emission decay (also known as positive beta decay), it emits a positron, an antiparticle of the electron with opposite charge. Such equipment can actually show unusual biological activity in the body as a 3D volume image. At the same time the 3D medical images in the next scene showing the parasite wrapped around Kawalsky's neck vertebra are at least partly made-up computer animation. See more
The second doctor ordered an MRI; however, the machine used was a CT (CAT) scan. See more
