I appreciate you taking the time to respond to my questions. No, spoilers are no issue, as this is my 5th or 6th reread of the series at this point.
Thoughts:
#1- Makes sense.
#2- I dunno, That may be the reason, sure, but unlike Egwene, Aginor had hundreds of years of training with the power. I believe you, but it still feels very odd to me that he would be foolish enough to manage that. Also, I find it hard to believe that the Dark One would revive a minion who killed himself. That seems like the epitome of weakness/idiocy.
#3- Makes sense; the Tower deceives about everything else, and we know they lie to their own members, so no big surprise.
#4- Alright, thanks. Kind of disappointing that nobody knows, but it has always felt different from the other things Rand achieves later on; I've always felt that the Eye was a remnant from earlier visions of the story.
