What was the deal with Walt? What was special about him? And if he was so special, why were Walt and Michael almost completely absent from the finale?
I've always thought that Walt got his specialness from his mother, or possibly a combination of his mother and father. Susan died from some weird blood thing (Ep: 1x14, Special) and that disease may have been what made Walt special. It seems if he was upset, he could make birds die. It might also be that he could make other animals appear, like when the polar bear tried to get him after he read Hurley's comic with the polar bear on it. Although, we know the polar bears were already on the island because of Dharma and that had nothing to do with Walt.
Why do you think Walt was special?
