الموسم 1، الحلقة 6: A new physician arrives in Camelot and stands to threaten more than just Gaius's job. A mysterious and scarred man enchants a bunch of flowers which are then delivered anonymously to Morgana. As she sleeps, an enchanted beetle creeps from the bouquet and enters her ear, making Morgana seriously ill. Gaius is summoned to help but, unaware that it is magical, cannot find the cause of the disease. Edwin, the scarred man, arrives at the palace – he is a physician and claims to have a cure for all ills. Desperate for answers, Uther urges him to start examining Morgana right away. Edwin secretly uses magic to remove the beetle from Morgana's head, thus curing her of the illness. Though grateful for his help, Gaius is suspicious of the mysterious stranger and his methods. Uther, meanwhile, is impressed and encourages Edwin to stay on in Camelot. Merlin is curious about Edwin and takes it upon himself to see what he can find out about this mysterious stranger. Snooping around the physician's chambers he finds a wooden box of "dead" beetles. Reading the spell on the lid, Merlin accidentally conjures the beetles to life. Edwin catches Merlin and realises he must have magical powers to be able to perform such a feat. Meanwhile, Gaius starts his own investigation, and enlists the help of his old friend, Geoffrey of Monmouth. Gaius manages to get his hands on a copy of an old records book from the time of the Great Purge. Studying the book from dusk till dawn, Gaius finds what he was looking for – evidence of Edwin's true identity. Deeply concerned for the King's safety, Gaius visits the Great Dragon looking for advice, but doesn't like what he hears and leaves Camelot. Merlin is devastated.
