Rereading the section with Ramshalan, am still a little unsatisfied with Graendal's demise.

A man appears from the Dragon Reborn, alone, at _her_ palace door. After Compulsion, the interrogation inevitably would have to lead to what the Dragon had said to him, and the very strange riddle the Dragon had queried: "How do I outthink an enemy I know is smarter than I am." That by itself and given that the Dragon had woven a hole in the air directly to her palace, AND the fact that Rand outrightly identifies her: "My current foe understands the others in a way that I cannot hope to match. So how do I defeat her?" (567) would she not be in the least bit suspicious immediately?

Yes the chess game of wills is one thing, but effective the moment she compelled him and discovered the dialogue that the Dragon had said, she's knows he knows where she is.... Why stay at all? Especially when she's got to think to herself how is he getting back to Rand (with no horse, or entourage....)? The thought that the Dragon has got to be somewhere in the vicinity has to have crossed her mind, right? Her hiding place has been compromised, that is an immediate fact.

Add to that, that if Aran'gar were there, wouldn't Aran'gar have felt the buildup of saidin for the balefire; it was a lot of balefire after all.... (the passage reads that it was a moment to be sure, but a long one)...?

I know Sanderson kind of dumbed her down and forgot some of the details of her scenes, but given just how smart she is, I'd think she'd not be so foolish as to just Compel him and send him on his way and then resume her idle fancies....
