Paradise Lost

"Paradise Lost" is the fifteenth episode of the sixth season of Stargate SG-1.

Synopsis
Harold Maybourne leads SG-1 to an arch on another planet, where he transports himself to "paradise." Unfortunately, Colonel Jack O'Neill is also stuck with him. As they have to cope with each other, Major Samantha Carter tries her best to find the two. Meanwhile, O'Neill suspects Maybourne is starting to act paranoid.

Previously on Stargate SG-1
Colonel Harold Maybourne of the NID is imprisoned for treason. After assisting Colonel Jack O'Neill, Maybourne managed to get himself transferred to a less secure facility allowing him to escape.

Plot
Colonel Jack O'Neill is visited by Harold Maybourne, a man notorious for his illegal NID operations. Maybourne tells O'Neill that he knows about the goal of Frank Simmons: when Simmons tried to steal the Prometheus, it was to find a planet with a cache of weapons. Maybourne tells O'Neill that he knows the Stargate address of that planet.

SG-1 visits the planet P5X-777 without Maybourne. There they find out that the writings on the planet aren't of Ancient origin but instead belong to the Furlings, another one of the Four Great Races. However they don't know how to unlock the seal to get to those weapons, so they have to trust Maybourne, who later goes with them to the planet. Unbeknownst to SG-1, Maybourne has his own agenda in mind as he escapes from SG-1 and flees through the alien door, which turns out to be a transportation device; however, he is immediately pursued by O'Neill. Major Samantha Carter and a team of scientists try to activate that device again, but fail. Searches come up empty; O'Neill and Maybourne are nowhere to be found.

The two adversaries are in the meantime spirited away to the planet's moon (though no one is yet aware of this) where Maybourne explains to O'Neill the significance of the moon, described in legend as an "alien utopia" where Maybourne had hoped to hide away from his checkered past on Earth.

As Carter begins a frantic project to reopen the alien portal, O'Neill and Maybourne discover an empty shell of a civilization with no survivors left to explain their demise. They both realize they may be stuck on this alien world indefinitely and begin to dig in for the long haul, which Maybourne doesn't make easy for Jack. After a week the scientists have to give up (much to Carter's protest) and even the Tok'ra don't find anyone on the planet.

O'Neill begins to uncover clues to the utopia's fate and notices increasingly paranoid behavior from Maybourne. Maybourne hears something at night, demands Jack's pistol and even runs away after a few days. Finally, O'Neill discovers Goa'uld skeletons in some of the houses with a mysterious plant nearby that he identifies as the substance he saw Maybourne eating all throughout their stay on the alien moon. O'Neill returns to discover that Maybourne has taken weapons that O'Neill hid with the very intent of keeping them from the delusional Maybourne. However he also starts to become paranoid.

Back at the SGC, Carter is crying over O'Neill's absence; Teal'c comforts her. Later, Carter realizes that O'Neill and Maybourne were sent to the alien moon from MALP playback footage. By this time, however, Maybourne's paranoia has erupted into a firefight with O'Neill. When O'Neill tries to explain how the plant has affected Maybourne's mind, he is answered with more gunfire from Maybourne. The fight ends with O'Neill shooting Maybourne, subduing him. O'Neill cares for the wounded Maybourne who now, with a cleared mind and injured body, can understand that O'Neill isn't trying to kill him. Soon afterward, a Tok'ra Tel'tak, whose aid was enlisted by Carter, flies over O'Neill's position, rescuing him and Maybourne from the empty paradise. Jack also says he will convince the Tok'ra to bring Maybourne to a nice planet on which he can retire.

Goofs

 * The "Goa'uld" skeleton that Colonel Jack O'Neill picks up with his knife is clearly that of a snake.
 * After almost a month on the moon, O'Neill has only a light stubble on his face. He should have something more resembling Harold Maybourne's beard.
