I don't like his back story nor was I impressed with his latest on-screen appearance (i.e. "Grrr! Lews Therin is mines! Because he was always a second earlier than I was, a bit more handsome, an inch taller...and if Semirhage has harmed him before I could, blah blah etc etc.".

If he is behind all the events in Murandy, I will be very annoyed about all of the build up he was given. At this point, I will only be satisfied if he went to all the mirror worlds to bring back multiple versions of Rand to destroy everything as a massive army of clones, raised a massive army of channelers from the Isle of Madmen or conquered the rest of the planet while everyone else diddled around in the Westlands.
