Cassandra and Laocoon in The Trojan Horse
These two Trojans with the gift of prophecy fail to hold their countrymen back from dragging certain fate in past the walls. Cassandra is a beautiful princess who used to get down with Apollo, but he cursed her by spitting in her mouth so that she would be able to tell the future, but no one would believe her. Laocoon also tries to check the Trojans before they wrecked themselves, but Poseidon sends a couple of snake thugs to choke him out.
