I'm not sure if this has been posted before or not, but I think there's a chance that Moiraine is a darkfriend. Seriously, I don't think Moiraine is a darkfriend, but there's still a little bit of 'evidence':

"The sight of Lanfear hit her like a blow. Not surprise, but the shock of seeing what had been in her dreams so often since Rhuidean."

- I'm sure Lanfear talks to Kadere in the waste about how she was in his dreams. Maybe Lanfear had showed Moiraine how to set up the angreal in Moiraine's dream so Lanfear could take it & use it against Rand. Everyone just assumed that Moiraine sees this future in Rhuidean, but unless I'm mistaken, it doesn't say anything about 'seeing' this scene in Rhuidean, just about seeing it in her dreams since then. She also says she took the angreal out of Rhuidean even though she didn't like it - perhaps darkfriends, etc, have a list of angreal/ter'angreal that if seen must be gathered or something? Perhaps not, but just a thought.

Why hadn't Moiraine killed/done something to Rand? Lanfear had told Moiraine she wasn't allowed to touch/kill Rand, but to gather as much information on him & help him with all her ability to defeat the DO so they could rule together.

Also, maybe Moiraine didn't like being a Darkfriend, or was like some kind of 'double agent' a good person playing the on the bad side to see what their plans are? That might be why she set up the door, knowing about finnland from her first visit, and that the finn would kill Lanfear if they caught her or something? Okay, maybe not...but we'll never know until book 12, if then.

So it's not the most concrete of evidence, just something that had me thinking all the same. Any other thoughts?
