At one point I had the vague idea that She would help him silence the voice of LTT in his head and that would be letting LTT die like he wanted so badly. Of course the fusion of the two dragons thing or "Super Rand" kills that dead (not that I gave that much thought after TGS, anyway) So if Demandred is going to kill Rand, then whats Ally going to do, distract him by yelling "Hey, Randdy-poo!"??? Just askin'
