I think you're right. Cadsuane will march into the middle of the last battle and give S.H. a good spanking which will shock the dark one so badly that he will die of embarrassment. "There, Boy, I've done it all for you." Oh, and Rand will laugh so hard that he falls over and hits his head on a rock, thus spilling his blood then Nynny will bring him back from the brink of death.
