I'm not sure if this is a theory or a question. I've just discovered the WOT on the web so this may have been discussed already - if so forgive me. In LoC it seems to be established that men cannot detect the ability in other men, p. 112: Taim channels and "Rand could feel the power in Taim, though only a small amount, and could see the thin flow of Fire the man wove. The flame brought a startling relief to Rand, startling because it was proof Taim really could channel." this seems to show that male channelers cannot detect the inherent ability in other men. then on p. 116-7 Rand has Taim seize saidin in order to sense how much Taim can hold - again another indication that the inherent ability is not detectable, only when power is actually being held.

later - after Nynaeve Heals Logain, he tells her "You know, I saw a man once who will cause more trouble than I ever did. Maybe it was the Dragon Reborn I don't know. It was wqhen they took me through Caemlyn after I was captured. He was far away, but I saw a. . .a glow and I knew he'd shake the world." (p.602, LoC)

The only other time someone has seen a "glow" surrounding a character is Nicola detecting the ta'veren ability in Mat when he rides into Salidar. Also, in (from what i recall) when we've seen male channelers detecting others holding itis only while holding and a sense of how much they can handle. So, how come Logain sees a glow around Rand when he is just hangin' out on the palace walls and being a pesky tourist? Has this already been discussed to death elsewhere? if not, why should it matter that Logain can see ta'veren as it is a "minor Talent" and pretty worthless since all the AS and pretty much evreyone else in RandLand seems to know that Rand, Mat & Perrin are ta'veren. There can't be too many others walking 'round. Thoughts orcomments?
