But doesn't Rand's power as a ta'veren/dragon reborn make it so he can identify darkfriends? Remember when he lined up all the High Lords and Ladies of Tear and was able to know exactly which ones were enemies? And wasn't Alivia present at the classing, something that Lanfear noticed because she was suprised at her incredible strength? Wouldn't she have attempted to kill Rand and stop the cleansing like the rest of the forsaken. The idea that she was ordered to spy on Rand and be off the collar by sul'dam has merit, but I just don't see it. Damne freak out whenever they are off the collar, going insane and lashing out with the power whenever they are out of their collars. I definitely agree with the fact that Alivia is strange though, her mannerism is completely opposite that of normal damne. Maybe she just has an adnormal disposition, but is there any chance she might be reborn soul who has awakened former memories? Just an idea, I don't see her as necessarily bad. 

Has anyone else thought that Sammael could have killed and replaced Taim after his somewhat sketchy disappearance in Shadar Logoth. As I recall, Rand never actually saw Sammael hit by balefire. Not only that, but in the The

Fires of Heaven

Chapter 34, "A Silver Arrow"

A compact man of middling height, with a livid scar across his face and a square golden beard, leaned forward angrily. His chair was heavy wood, carved with columns of armored men and horses, a steel-gauntleted fist clasping lightning at the back's peak.

the emblem on Sammael chair is the same on as the Asha'men have. If Rand didnt make this emblem, could it be Sammael rehashing it? and I believe there was a strange quote by Taim regarding a fish he once saw drowning in Illian. He's Saldean, discounting the fact he may have traveled abroad, could be possible evidence. Plus the idea that Sammael likes his armies, and could have easily killed the original Taim when Rand wasn't looking.
