Airdate: July 13, 2001

On Velona, SG-1 finds a deserted world and the ruins of an ancient civilization. As Carter begins to examine an unusual alien device, she inexplicably passes out, and is ordered to take some time to rest. At home she is confronted by an enigmatic young man who is able to pass through solid objects and who explains that he is Orlin, from Velona. He exists in a non-corporeal state, and has followed Carter back through the gate, professing his love for her. Surveillance cameras are set up at Carter's home, but because Orlin appears only to Carter, the others are doubtful that the alien exists.

At the SGC, Colonel Simmons has arrived from the Pentagon to demand testing of the alien device on Velona, which has been determined to be a weapon of great power. Orlin takes human form in an attempt to remain close to Carter, but he warns her against testing the weapon. He had been banished by the Others of his race for breaking their most sacred rule. He had helped the people of Velona to build the advanced weapon for self-defense, but their use of the device for conquest led to their destruction by the Others. Now SG-1 is about to repeat their mistake.

As SG-16 prepares to power the alien device on Velona for testing, Simmons continues unauthorized surveillance of Orlin, whom he is determined to take into custody. In an attempt to prevent further destruction, Orlin builds a small working model of a stargate in Carter's garage, and uses it to escape to Velona. However, SG-16 prevents him from deactivating the device, and he is mortally wounded. As his spirit fades, the Others grant him a second chance. He is allowed to ascend once again, and as he returns to his non-corporeal form, he carries the weapon away moments before its detonation.
