At about the two minute mark, the background riff sounds just like the intro theme.

I was rewatching season 1 when me father walked into the room.  He asked what I was watching and I told him WOT.  He said, "Cool how they reworked that Zeppelin song."  When I asked what he meant, he said go listen the the third Led Zeppelin album, the song 'Friends'".  I did, and damn if he is not right.  I am looking for others thoughts.  Listen all the way through the song.

Sanderson's tidbit that he can share in a few years is about Nakomi.  And he refers to it as small as the answer has been in front of us the entire time.  Think about the the letter Moraine leaves for Rand following the confrontation with Lanfear that was associated with her "Death".  Then re-read the words Nakomi speaks to Rand at the end of the books.  (TFOH) "You will do well."  (AMoL) "You have done well."  Figure it out yet?  As to why Aviendha could not sense Nakomi channeling, Nakomi wanting to ensure that Aviendha took a double dip, and why she was there for Rand in the End; it all ties together with Rand's pipe (the future of magic is not about using weaves) and thinking about who was the most dedicated to Rand's cause (willing to submit and die for him and carried the cause from the moment of his birth to the moment of his "Death").  It is future Moraine.
