[Movie] Merlin (S1E06) A Remedy To Cure All Ills
Morgana falls ill with an unidentified brain disease which Gaius is unable to cure. A mysterious healer, Edwin, proves that his ‘remedy to cure all ills’ seemingly helps her, but actually removes the cursed black beetle that caused the illness. Uther retires Gaius and instates Edwin as the new court physician.
Gaius secretly gets court archivist Geoffrey to give him access to the sealed records of Uther’s purge of magic, proving Edwin’s parents were executed as sorcerers. Edwin threatens to expose Merlin if Gaius tells Uther, leaving Gaius with an impossible choice. After consulting with the Great Dragon, Gaius decides to step down and leave Camelot (calling Merlin the ‘son he never had’). Edwin uses another beetle to condemn Uther to an agonizing death. Gaius returns at the last minute, but it takes Merlin to save the day.
