Nimueh knows who Emrys is, so it won't be her. The only people, other than Gaius & Morderd, that know who Merlin is... are dead. lol Nimueh ain't comin' back. Mordred however MUST be kept alive die to the legend. With everyone who knows Merlin's secret dead, the only one who CAN return is... MORDRED!!! LOL
