Good to see Egwene back also - if it is a little jarring and obvious retcon, it needed to be done and I am happy.

“Thank you very much for the advice,” Elayne said, “which I will ignore, as I ignored Birgitte when she said the same thing. Mother, what is it you wished to discuss?”
Egwene handed over the letter she had been working on.
Elayne scanned the top of the letter. “To Rand?” Elayne (she) asked.
“You have a different perspective on him than I. Tell me what you think of this letter. I might not send it to him. I haven’t decided yet.”
Elayne's face gave nothing away as she read the letter. She looked serene. As an Aes Sedai should. As a Queen should. How would she react to this? Egwene placed much trust on Elayne. The woman was in love with Rand, but Egwene trusted her to place the rationality of their arguments above her feelings. At least, she added to herself, I hope I can.
“The tone is . . . forceful,” Elayne noted. She did not seem surprised.
“He doesn’t seem to respond to anything else.” Egwene could well remember their arguments as they grew up in Emond's Field. Him saying the most infuriating things. Her trying to make sense. At least, that was the way of it most of the time.
They had thought they would marry, then, yet that hadn't stopped them from rubbing each other the wrong way every so often. Now... now we stand as leaders of the world. An ancient man in the mind of a boy, and a girl bearing a title almost as ancient. They couldn't walk away from each other in a huff this time.
After a moment of reading Elayne lowered the letter. “Perhaps we should simply let him do as he wishes.”
“Break the seals?” Egwene asked, startled. “Release the Dark One?”
“Why not?”, Elayne asked, as if asking why there should be no rain from clouds.
“Light, Elayne!, Egwene said, troubled. If her closest friends doubted her course, what chance did she have of convincing Rand? And Perrin too, as if one mule headed stubborn man weren't enough. All they needed was for Mat to appear, and the entire lot of them could talk sense till they were hoarse, and nothing would change.
“It has to happen, doesn’t it?” Elayne asked. “I mean, the Dark One’s going to escape. He’s practically free already.”
Egwene rubbed her temples, thinking. She chose her words carefully. Elayne's point was not without merit. Perhaps if she had she not had that dream before Rand came, she would have seen things differently too. But now... now she knew. This was not instinct. Not even just the Dream, which she hadn't even revealed to the Wise Ones. The Tower was a treasure trove of obscure knowledge, and on this issue, she had found plenty of useful nuggets. Time to see if they were worth anything.
“There is a difference between touching the world and being free. During the War of Power, the Dark One was never truly released into the world. The Bore let him touch it, but that was resealed before he could escape. If the Dark One had entered the world, the Wheel itself would have been broken. Here, I brought this to show you.”
