this is my version of how Merlin's magic could be revealed: Morgana attacks Arthur with magic, believing that his death will ensure that magic returns to Camelot, but Merlin, disguised as an old man (Dragoon the Great), arrives and blocks her attack with his magic, briefly knocking her out. Merlin then transforms back into a young man, revealing himself to have magic, with Arthur, Gwen, and even the Knights of Camelot watching, much to their shock. However, Morgana, who has recovered, also witnesses that and stares in shock at discovering that her worst enemy Emrys is actually her former friend Merlin who she thought was just a servant. Then Morgana is angry and engages Merlin in a fierce magical duel, but when realising she cannot defeat him, attacks Arthur again and Merlin takes her blow, attacking her at the same time with his magic, forcing her to flee. Arthur takes the dying Merlin back to Gaius to be saved but is shocked and resentful that Merlin never told him the truth. Gradually Arthur accepts that Merlin had a reason to hide his magic and thanks Merlin for saving his life when Gaius cures him. Finally realising that magic can be used for good, Arthur then returns magic back to Camelot, so in my version both Merlin and Morgana play a part in returning magic back to the kingdom.
