If you've done MSQ through 3.4, you might have noticed that Thancred's eye color changed twice. The original color, hazel, changed when he was dumped out of the aether flow. At that time we knew Y'shtola was blind due to the whole event of escaping from the end if the 2.x story, and her eyes were the milky white associated with blindness. When we find Thancred, he is not blind, but his eyes (yes even the one under the patch) are a whitish-blue. The only explanation we get is that due to the time in the aether flow, Thancred was unable to use aether (i.e. can't teleport). We are led to assume that eye color change is due to that. At the beginning of patch 3.4 though, we see Thancred with his old eye color again. Nothing is ever said within the story as to why this is. So, what happened? Did the ill effects of the aether wear off? Can he use aether/magic again? Was the color change a mistake? Was there ever supposed to be a color charge in the first place?
