SG-1 is captured whilst trying to destroy the Goa'uld ships that are approaching Earth. They join up with Teal'c's mentor Bra'tac in order to save the day. And Teal'c gets to fly a Death Glider. Hooray!

Teal'c shoots the assassin (Ashrak) that is holding Jackson at gunpoint after killing Jolinar (a Tok'ra who had melded with Carter).

When O'Neill is pinned to the wall by the mysterious orb, Teal'c keeps him company. Undomesticated equines would not drag him away!

Bra'tac tells the SGC that Rya'c is in danger. SG-1 goes to Chulak, where they find that Teal'c's wife Drey-Auc had married his old friend Fro'tac. Eventually they rescue the boy, who's been brainwashed with Nishta. When they've got him back to Earth they discover he's got two teeth containing viruses which when combined would have had disasterous effects. Teal'c uses a Zat gun to reverse the brain washing, and mother and child are sent to live in "The Land of Light".

Teal'c gets stung by a big ugly bug, and his DNA starts mutating. The dastardly Colonel Maybourne takes him away, but he escapes and removes his larva so the tranformation will be quicker. He hides in a deserted building in Colorado Springs where a girl named Ally befriends him. She calls O'Neill and they manage to reverse the process.

SG-1 discover a device which swaps Jackson's consciousness with that of its inventor, Machello. When O'Neill and Teal'c are sent back to recover the device THEY swap. Teal'c has to nurse O'Neill through the ritual of Kel'no'reem in order to save his body. Carter eventually figures out how to get everyone back into their own bodies.

Teal'c's old boss Apophis is brought back from a planet, and turns into a prune. His body is sent through the Stargate to the rather grumpy Sokar.

SG-1 have been captured, and Teal'c wakes up in the SGC after a long period of unconsciousness. When he finds out they've given up looking for SG-1, he asks if he can leave Earth.
