It means just as it sounds. Sure my brother has his primitive talents, but you know as well as I that if left alone he would flounder about aimlessly, because he does not have it in him to make difficult decisions.

[There's was a somewhat protective underlying tone that he knew what his brother needed more than she did. In his eyes he couldn't see his brother as anything but the doofus he had been growing up, that he had to try and toughen up. For all his bitterness he could not quite shake that habit. Of course after talking about it, it only served to agitate Illidan and make him feel the need to act more petulant.]

I am not in the mood to sleep.
