Young Doctor


The team, now designated SG-1 (initially there will be nine exploration teams in all, more will be added later) 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

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 »


Jack O'Neill: Listen, um, I gotta ask you something. It's not easy for me.
Major Charles Kawalsky: We're friends.
Jack O'Neill: If you don't make it... can I have your stereo?

Dramatic and Tragic Episode
17 April 2015 | by (Rio de Janeiro, Brazil) – See all my reviews

Colonel O'Neill asks to General Hammond to let Teal'c join his SG-1 team but Hammond is reluctant since the alien hosts a Goa'uld. The arrogant Colonel Kennedy comes from Langley and wants to use Teal'c as a guinea pig to study the Goa'uld. Meanwhile, Major Charles Kawalsky is not aware that he has a Goa'uld inside him and has headaches and blackouts. He goes to the infirmary and kills the doctor, trying to escape through the gate. However he is captured by O'Neill and Dr. Warner finds the alien form around his spine. He decides to submit Kawalsky to a surgery to remove the Goa'uld. Will he succeed in the surgery? And what will be the fate of Teal'c?

"The Enemy Within" is a dramatic and tragic episode, with another great story. Kawallsky was a promising character and his loss was very sad. The attitude of General Hammond shows that he is a qualified leader, protecting his men. My vote is eight.
