I’m just now, apparently 3 years or so later, finding out about Sanderson saying this, well, this horrid thing. Frankly, as far as my own personal head canon is concerned, I’m going to have to continue thinking of this whole situation as if I never heard about BS saying Lanfear is alive. Why? Well, like most, it would seem, I think it detracts from Perrin’s character arc and makes him seem like a stupid pawn and Jordan and BS spent 13+ books telling us that Perrin only SEEMS slow but is in fact just thoughtful and careful. Also, BS is spouting bs when he says there are clues about this in the buildup to it. Lanfear/Cyndane didn’t seem to be acting out of character to me; she just seemed like she was becoming more and more desperate as a final conclusion was getting closer and closer and that final, ultimate rejection from Rand seemed to really push her even further over the edge. As it is, the scene reads perfectly as her underestimating Perrin, just like most do when they don’t bother to really look at him, and her being rushed and super desperate. Also, it’s a perfect ending for her.
