Let us make the circle of suspects wider. People mentioned here are Lanfear, Padan Fein, Moridin and fellow Chosen. I propose to add Aviendha, Moraine.Aviendha. Asked "Should I kill him?" Was it before or after Andor? I do not remember. I thought it was Rand she meant. But she does not say it anymore. I wonder if something in her warrior code makes her kill the witness of her "shame". Or probably she guessed who he was when they came back from Seanchan place. Was she stupid enough not to understand? Weak point is Asmodean's reaction. Could he be afraid of Aviendha? Moraine. She knew. She disapproved. And she won't be in for a while. Weak point is the same. Lanfear. All reasons here are good, but it seems she appeared somewhere in the DO dominion with somebody that looks like Asmodean? Padan Fain. Nothing points to him beside the fact that he is that sort of fella'. And has a knife for the job. Fellow Chosen. They are undistinguishable for the case. Full symmetry, no use to guess. Moridin. Suspect #1.
