I think Leigh brought it up in her re-read of this book, Rand seemed to go all kinds of mad in the book. It seemed weird and almost accelerated, especially since he seemed to go back to 'normal' following it.

Yeah, I believe that Rand's dramatically increasing-then-decreasing madness in books 3 and 4 are due to the fact that RJ thought (while writing book 3) that the series would only be a few books longer, but by the time he started writing book 4, he knew it would last longer, and needed to draw the madness out.

Physically, Egwene.  Emotionally/Mentally/Socially, Min.  I cannot stand Egwene anymore, but she's still "hot" (according to her description).
