Mark,

I don't think a double bond situation would allow the non-foretelling channeler to "use" foretelling   It is not a Talent that can be used.  It simply happens to the person.  This is what makes it difficult to determine if it is power related.  Like Min's ability, she has no control over it.  Now take Dreaming, Egwene was able to control that Talent. Would the double bond have the Talent-sharing effect on that?  

Come to think of it, all the abilities to view the pattern have little to do with channeling.  Min, Egwene, and Perrin all have ways of seeing glimpses of the Pattern with their specific abilities.  So maybe foretelling is just another way of doing this, but for channelers. 

@Jack of Shadows,

What about Mat? He is a commoner and has become the Prince of Ravens. According to Fortuona's thoughts, Mat could potentially want to assassinate her to ascend to the throne. Which means a spouse has the ability to reign. And Elayne granted Perrin titles and stewardship, above even other Andoran Lords. Which means he is not a commoner anymore. So the possibility of Perrin wearing the Broken Crown and being King is there.

@Metal Head and Gwennifer,

I have felt that the "three shall be as one" line to refers to the Rand/Lews Therin/Moridin situation. Since the crossing of the balefire streams, they have been connected, yet apart from each other. With Rand and Lews Therin complete now, Moridin must somehow be fully connected to Rand in AMoL.
