Lost Finale - Aarron & Jin/Sun's Daughter?

I think you have to intepret even them meeting in the church as somewhat of a unreal environment, in that case you can say that that Aaron is not the Aaron with a soul, rather just a symbol for all the survivors ping on together. Or maybe its how they p on according to how they remember, and for Aaron it will be in another way, and that it can happen in multiple ways. We're pretty much throwing the rules out on time and space. Aaron probably has his own ping in a different way, one that he remembers as he pes through with a significant other of his as he is grown.
