Then why did LTT/Rand not do that? Why ask Nynaeve to perform an extremely delicate operation that could fail due to her lack of knowledge and which took nearly an hour, when all that was required was a quick gateway next to a stedding and pushing the boy inside?



Did SH know exactly what orders Elza had been given? We readers may know what orders Verin gave, how Elza interpreted them and that it may not have been required. But even if SH could see the weaves, he might not be able to tell what commands were given. From shadows POV, it would have been better to play it safe in such case, rather than risk having some hidden compulsion command kick in at the worst moment and ruin everything.



I should add that BS has also said or atleast implied that SH's power cutting trick only works on those who have sworn themselves to the shadow. This would mean that even if SH can disrupt tied off weaves of darkfriends, he would not have been able to do so for Cadsuanes weaves since she has not sworn to the shadow. He needed Elza to go and break the wards. The compulsion on Elza was made by a DF (Verin) yes, but again instantly nullifying it could have killed Elza as was said earlier. Bottom line is that as of yet, we don't know the full extent of SH's abilities.
