This is simply ment to support what perringoldeneyes
was saying about our friend Moiraine.
There are several things early on that are so bleedingly obvious it amazes me people arent buzzing about them.

Lets take a trip down memory lane untill we end up
in TDR. We have Perrin, Lan and of course Moiraine.
Fail and Loial are also in the scene I will refer to but they play no major role.
Perrin and co. arive in Illian in search for Rand
and stop at an inn. They are attacked by greymen(whatever happened to them anyway?) and once they are disposed of Moiraine goes out into the city to look for information from unknown sources.She returns some time later and tells everyone that Sammael is the ruling lord in Illian,or the next thing to it.Does this seem strange? She goes out and finds that not just one the Forsaken rules,but she knows EXACTLY who he is.Not information even Thom could pick up in gossip over wine in an inn.

They flee the city being chased by Darkhouse.They esscape Sammaels darkhounds by Moiraines use of balefire...where did she learn how to do that?
forbiden by tower law,alot of Aes Sedi not powerfull enough to use it undoutedly and wouldnt teach it to her even if they knew it.
You might be thinking right now that this is just coincedence.

Lets skip ahead shall we?Perrin and co get to Tear.
And as you no dout have guessed its the same story here. Moiraine leaves,comes back to tell everyone that she knows that Be'lal is the highlord Samen.(Spelling?)

Our little Aes Sedi is becoming less inoccent by the chapter.

Lets jump forward to FoH.Its from Rands view after the scene on the docks.He is reading Moiraine letter.In it she reveals that she knows about Asmodean.She never refers to him by name but its obvious she knows the situation.This is not explainable by her going through the arches because
Asmodean identity disscused prior to the scene on the docks, or afterword for that matter.

I hate to give you so many questions with no provable response but I suppose we shall just have to wait to see what this chicks dark secret is.
