Forsaken

Forsaken is the eighteenth episode of the sixth season of Stargate SG-1.

Plot
SG-1 is on a planet for scientific researches when O'Neill suddenly finds a photo. O'Neill and Carter are then contacted by Jonas, who has found a crash-landed ship, which they can't identify. Suddenly three persons arrive and threaten them with weapons. They introduce themselves as the Hebridans and tell them how they crash-landed. While they talk they are watched by two unknown aliens. SG-1 agrees to help them repair the ship.

While Carter and the ship captain named Aden examine the ship, the people outside are attacked by the two aliens. During the shootout one crew member is wounded and one of the aliens is killed when suddenly one of the crew members activates a loud sound and the other alien is forced to flee. SG-1 is then informed that the aliens are a deadly enemy and killed the other crew members.

Back at Stargate Command General Hammond is informed about the situation and where they might have come from. SG-15 also comes to the planet to help. The wounded female crew member is in the infirmary of SGC and talks with Jonas about her life and the Stargate, which the Hebridans don't know. On the planet, Carter helps repair the ship, while talking with Aden. Outside, the other alien sneaks to his dead partner but is confronted by O'Neill, when one of the crew members shoots at the alien, who then runs away but is chased.

At SGC Jonas tries to learn about the ship, which is named Sebrus, while Hammond informs him that someone tried to hack into the computer. Back on the planet O'Neill and Teal'c find the camp of the aliens when they hear weapon fire. Carter is in the meantime able to repair several systems from the ship, while she talks with the captain about their life and their families. Back at SGC Jonas shows the female crew mate his room, where they kiss. Suddenly Jonas is called by General Hammond and leaves.

Back on the planet, Sam repairs more systems and suddenly sees a video of an emergency call, in which a person calls the Sebrus a prison transport ship, much to Sam's shock. Outside Teal'c and O'Neill are confronted by the alien. He tells him his name is Warrick and that he is the captain of the Sebrus. Inside the ship Sam confronts Aden with her Zat and informs him about what she learned. She then ties him up while he tells her that he helped the prisoners to gain control over the ship. He also tells her that the aliens are his prisoners. Outside Warrick tells them that three years ago they transported the prisoners but then they crash-landed on the ship. When he and his first-mate went looking for food, the prisoners then escaped and since then they are fighting constantly. O'Neill then shows him the photo of the woman which he found in the beginning and Warrick identifies her as his wife. He also asserts that his species, the Serrakin, once freed the Hebridans from the Goa'uld.

Afterwards they are contacted by Sam who is then beaten down by another prisoner. At the Stargate Jonas and the woman named Reynard come through. Aden is in the meantime freed and he then stuns Jonas. Reynard informs him of criminal opportunities on Earth. They then tie up Carter and use her as a hostage, but her team mates are able to free her. Back at the gate the prisoners use Jonas as a hostage and try to flee through the Stargate to a stolen address, but they find themselves at SGC (Jonas having arranged for them to steal that address) and are imprisoned.

In the end SG-1 says goodbye to Warrick, who thanks them. Afterwards he leaves.
