Jack, Sam, Daniel and Teal'c visit a desert planet with skyscrapers and buildings but no living soul. Out of the blue, they are attacked by giant bugs and Teal'c is stung by one insect. The SG-1 needs to flee back home when a swarm of bugs fly toward them. Dr. Janet Fraiser examines Teal'c's infection and realizes that the virus left by the bug is killing Teal'c and his symbiotic is not healing him. Further, in his blood there is also a different DNA. Sam suggests to General Hammond to summon the prominent Dr. Timothy Harlow, who is an authority in DNA research. Soon Colonel Harry Maybourne comes to the SGC to take Teal'c with him. Hammond does not succeed to contact the President to overrule the order and Maybourne and his men take Teal'c in a van. However, Teal'c manages to escape and hides in an old building where the girl Ally helps him. Meanwhile the SG-1 returns to the planet to capture one bug alive for research and discovers what has happened to the inhabitants of the planet that were covered by a cocoon and transformed into several bugs. When Ally meets Teal'c against, he is covered by a cocoon. Will Teal'c be transformed into bugs too?
"Bane" is a good episode of Stargate SG-1, where the strong Teal'c is affected by an alien bug. The story is engaging and the detestable Maybourne has an important participation with his arrogant attitude. My vote is eight.
Title (Brazil): "Bane"
