Ok I just got this really exciting and extremely unlikely theory, but the exciting is bigger then the doubt...

What if Grendal is helping Taim, not teaching him, but instructing and guiding. Taim then in turn doing the same to his men...

There is little to no evidence to back this up, so rip this to shreds if you want, no hard feelings :)

A bird cannot teach a fish to fly, nor a fish a bird to swim. Saidar and Saidin are too different - opposite genders cannot teach each other.

This is true Beckon, but I don't think the OP is referring too the One Power...

^ The OP not refering to the OP, what is this? :lol: Of course he means the True Power. However, replace Graendal with Demandred, and you have my theory right there.

I'm really sure its YOUR theory lol.

 

Like I said, I don't think she is teaching him how to use the OP, just using him as a pawn. Tell him where to go, what to do, and when, all in the name of the Shai'tan.
