Re-reading the series (again) and started to wonder about something in "shadow Rising". Does Rand "know" or have a clue that Lanfear & Ashmodean is in the peddlers(kadere`s) party? He is very suspitious towards Kadere himself, but Lanfear is also mentioned alot in his POV. It seems like he has an idea.

 

What does he know? Is there anything about that in the books.

I think he knows that some forsaken is with them but i dont think he knows for sure who is it until Lanfear and Asmodean showed up in his dream.

and he didnt know which was which because he was surprised when he found out who the were.

He knows Lanfear and Asmodean are with him, but he believes that they're Kadere and Isendre, when they're actually Jasin Natael and Keille. This is why in Chapter 36 he comments on Kadere's eyes and says he's a dangerous man. He believes him to be Asmodean.
