Plot Overview

The SG-1 team travels through the stargate to planet PX3-987, where another SG team has been making preparations to observe a black hole. But, when they get there, they discover that a strange disease has wiped out everyone on the planet. Everyone that is, except a little girl named Cassandra. As O'Neill and Teal'c remain on the planet to observe the black hole, Carter and Daniel return to Earth with the girl. Carter grows especially close to Cassandra and is shocked when she discovers that the chest pains Cassandra is experiencing are caused by a metallic device growing around the child's heart. Daniel and Carter are certain that the Goa'uld planted the device as part of a scheme to destroy the Earth's stargate. As the time bomb ticks down, Carter is torn between her love for the little girl and her knowledge that the child is being used as a Trojan horse by the Gou'ald.

Allusions and References

• Cassandra:

Cassandra was the most beautiful of the daughters of Priam and Hecuba, the king and queen of Troy. She was given the gift of prophecy by Apollo, who wished to seduce her; when she accepted his gift but refused his sexual advances, he deprived her prophecies of the power to persuade. At the end of the Trojan War, Cassandra foresaw the danger posed by the Trojan horse; the people of Troy ignored her warnings and the Greek soldiers hiding inside the horse were able to capture the city. During the sack of Troy, Cassandra was raped by the Locrian (or "lesser") Ajax, and was then given as a war prize to Agamemnon. She returned to Greece with Agamemnon, and tried to warn him of the danger which awaited him there; once again her prophecy was ignored, and both she and Agamemnon were murdered by Clytemnestra and Aegisthus.

Goofs
