Hmmm, I wonder if the mc will reach his "final form" by dying. He has already added shared sight and pain to the shadow. Now, he is going for shared appearance and hearing in the short term and shared experience in the long term. If he keeps adding shared abilities as both limitations and benefits, the shadow will eventually become indistinguishable from the MC except for the shadow being made of nen.If you add to that Moses dying as a baby (Cheadle mentioned this), the mc dying and fusing with Moses, and the mc's comprehension of Swamp Man giving inspiration and more power to his ability, I wouldn't be surprised if the MC's post mortem nen shadow literally becomes him.From there, with the influence of post mortem nens' usual effect, the MC may lose some limitations or get an increased effect from them. In addition, his nen may drastically increase due to it briefly becoming post mortem nen.
