MORDRED

Mordred (played by Asa Butterfield and Alexander Vlahos) is a child apprenticed to a Druid. His master is executed on Uther's orders but Morgana and Merlin protect the boy. Morgana claims to feel an inexplicable link with the boy which drives her to keep him safe. The Great Dragon later tells Merlin that Mordred will one day kill Arthur. Mordred is telepathic and calls Merlin "Emrys", claiming he knows who Merlin is and that they are "the same". Despite the dragon warning Merlin not to save Mordred, Merlin eventually helps Arthur to escape with the boy and return him to the Druids. He returns again in season two when Morgana goes in search of the Druids. By way of her telepathic connection to Mordred, he is able to sense that she has been bitten by a scorpion and needs medical help. It is also shown that Mordred's magic is powerful enough to kill four or five armed soldiers with a single spell, and Merlin, who was also present, appears to show concern over this. He returns in "The Witch's Quickening" when he, allied with a group of renegades, seeks an ancient crystal with the ability to show the future to those who wield it, but he is forced to flee when the bandits are discovered. As he escapes, Merlin attempts to stop him by causing a branch to trip him up, but Mordred retaliates by impaling two knights in the back with spears, grimly informing Merlin that he will not forgive nor forget this. Mordred's trademarks are his icy blue glare and green cloak. It is presumed he was about 11 in "The Beginning of the End", and about 13 in both "The Nightmare Begins" and The "Witch's Quickening".
