It seems to me that Rand has realised that Egwene is actually in command of the Rebels and not just the puppet he thought she was in WH. Wonder what brought about that change? My first thought was that it was due to Brandon, but I don't think he could make that big of a mistake in perception. Harriet and RJ assistant's would undoubtedly have caught such mistakes.

I wonder if Nyanaeve might actually have told Rand about the real situation in the tower. That alone would not have changed his perception but he would have to know that Egwene is the real power in the rebel camp. Otherwise, there would be no need to be so paranoid about Egwene.
