Towers of Midnight Book Tour, Harvard Coop, Cambridge, MA 7 November 2010Edit
Report by RDDK
I asked BS how, now that Mesaana is braindead and all, she got around the oath rod. He told me that one of the three ways the Aes Sedai had surmised was correct. Considering it probably would have been mentioned if they found an oath rod among her things, that it probably was the weave the investigators had rediscovered.
Addendum to report:
Also, for any RPers out there, I asked for clarification of Aiel male channelers. BS said that once they learned the taint was cleaned, no Aiel men were/would be sent to the blight.
