Now, I guess most people here thought that Moiraine would be needed to teach Rand laughter and tears. Considering that Moiraine's death is one of the things Rand most regrets, and her name is the first one on the list of dead women in Rand's head.

But, thankfully, it seems that Rand has now resolved his issues.

So, what purpose does Moiraine have now? Obviously she has some part to play, otherwise there'd be no reason to rescue her. Even if she can channel, she's no more among the strongest channelers, so her OP skills probably aren't the reason. I thought she would be needed to tell Rand that the Forsaken (Lanfear/Cyndane) are being resurrected, but now Rand knows that, too.

So, why do we need Moiraine? Does she know something important, perhaps concerning Rand's plan to seal off the DO?
