In my opinion, Gaz is defiantly NOT dead. His character was or should I say is too complex to be killed behind te curtain. If you remember, when Gaz thinks about having to be a bridge man the worst fate a man could face. That was early on when this was said, and immediately, I thought it would be interesting if he was forced to put his life in Kaladin's hands. I felt empathy towards Gaz for some reason, and there was defiantly something fishy going on about him having to pay those spheres. I don't think the light eyes would keep Gaz's death a secret and it would be known if he was killed. There are TONS of bridge crews so I think he is one of them, keeping his head down. The "darkness" he felt in his missing eye has more to it than just his brief thought about it, I think it might be in reference to the creatures Shalahn (can't spell) captures in her drawings. Bottom line is, Gaz and Kaladin have not concluded their grudge and they are bound to share some moments together in book two. Mr. Sanderson says the clues are there to know. Skar killing him just bc of what reason or reasons were they again? Anywho, they were my solid, Gaz's shady background and his low rank in the military are clues enough that he will be made a bridge man, and I am so excited to see him and Kaladin working together and Gaz becoming a better person.
