When a druid and his young boy apprentice are caught in Camelot, the terrified pair make a desperate bid for freedom with the palace guards in pursuit. Merlin hears the boy’s telepathic cries for help and ushers the child inside the nearest door, only to find Morgana and Gwen hiding there. To his surprise, Morgana covers for the boy and the guards pass.

Though the boy is saved, his druid master is caught and executed in the main square. Before the axe falls, Uther makes a strong speech, declaring that whoever is hiding the boy will be severely punished. The distraught boy refuses to speak, but continues to communicate telepathically with Merlin.

Merlin goes to the Great Dragon to ask him about the boy. The Dragon reveals that the druids predicted the boy’s arrival and that the boy is dangerous. The next morning, the boy is unwell. Morgana begs Merlin to ask Gaius for help and Merlin reluctantly agrees.

Later that night, Morgana attempts to free the boy but they are both caught and the boy is sentenced to death. Merlin returns to the Dragon. He wants to know why the Dragon warned him against the young boy. The Dragon is angry that Merlin defied his earlier advice and tells him that this boy is Arthur’s nemesis, Mordred.
