User blog comment:Longlivemerlin/Temporary? Or Permanently? Magic reveal talk! (SPOILERS FOR EPISODE 12 & 13!)/@comment-204.12.159.225-20121218142759

Merlin's magic is gone only temporary I think. Question is: without magic does he still have his dragonlord powers. I really do think so. I hope he commands the dragons against Morgana. Balinor is supposed to be in an episode I heard. Perhaps Balinor's spirit guides him. Or Kilgarrah dies giving Merlin his magical powers or something.

As for Gwaine. I thought he would have found out about Merlin A LONG time ago. I thought he would have been Merlin's confidant like Lancelot was. Alas I do hope he get to know about Merlin's powers. He is the knight that Merlin is closest to (disregarding Arthur of course).
