Throughout most of books 4 and 5 (ever since Rhuidean), Aviendha sticks as close to Rand as his shadow. He thinks this is because the Wise Ones have set her to spy on him, but
after they sleep together somewhere in Seanchan, he starts to fall in love with her and we realise that she's falling in love with him, and that ever since Rhuidean she'd known she was going to.
So why was she really hanging around him? Maybe going to is the operative word here, and she resented him for this before it actually began to happen - which was when? Unclear since we don't get any of her PoV until book 6. I did always think that her apparent hatred of him might conceal an entirely different feeling... On the other hand, I think we have proof that the Wise Ones did order her to stay close to him. Was this so that she could spy on him for them, or in the hope that they would fall for each other? Or even in the hope that other people would think they were sleeping together (as Isendre did in tFoH), cementing Rand to the Aiel in the eyes of others?
The following passage (tSR, pp. 834-5) seems to have hidden depths of meaning:
[Rand to Wise Ones] "You must know that I know. About her. That you set her to spy on me."
"You do not know as much as you think," Amys said, for all the world like an Aes Sedai with hidden meanings she did not intend to let him see.
Melaine shifted her shawl, eyeing him up and down in a considering manner. He knew a little of Aes Sedai; if she were Aes Sedai, she would be Green Ajah. "I admit," she said, "that at first we thought you would not see beyong a pretty young woman, and you are handsome enough that she should have found your company more amusing than ours. We did not reckon with her tongue. Or other things."
"Then why are you so eager for her to stay with me?" There was more heat in his voice than he wanted. "You can't think I will reveal anything to her now that I don't want you to know."
"Why do you allow her to remain?" Amys asked calmly. "If you refused to accept her, how could we force her on you?"
"At least this way I know who the spy is." Having Aviendha under his eye had to be better than wondering which of the Aiel were watching him. Without her, he would probably suspect that every casual comment from Rhuarc was an attempt to pry. Of course, there was no way to say it was not. Rhuarc was married to one of these women. Suddenly he was glad he had not confided more in the clan chief. And sad that he had thought of it. Why had he ever believed the Aiel would be simpler than Tairen lords? "I'm satisfied to leave her right where she is."
"Then we are all satisfied," Bair said.
He eyed the leathery-faced woman leerily. There had been a note of something in her voice, as if she knew more than he did. "She will not find out what you want."
"What we want?" Melaine snapped; her long hair swung as she tossed her head. "The prophecy says 'a remnant of a remnant shall be saved.' What we want, Rand al'Thor, is to save as many of our people as we can. Whatever your blood, and your face, you have no feeling for us. I will make you know our blood for yours if I have to lay the-"
What 'other things'? 'Lay the' what?
Thanks in advance for any answers!
