What do you think Min is theorizing about Callandor. I can't quite remember what she was saying to Rand, but she was telling him to be careful about his interpretations about the prophecies relating to Callandor.

In TGS, Min was focusing on the fact that the seals have to be broken, but in this book, she was really focusing in on Callandor and the prophecies about it.

Any theories on what she is thinking about, or how/if Callandor will come in to play when Rand "takes on" the Dark One or tries to seal the bore?

Personally, before ToM, I really didn't think Callandor would play a part in Rand's role sealing the Bore. I thought it would be used as a tool to help defeat the Shadow's army, with Narishma linked to a couple female channelers. Now I am not so sure with a few instances in ToM dedicated to Min talking about Callandor.
