For whatever reason I have only just realised that it was Christian holding Aaron in the jungle. I would agree that Jack knows he is related to him in the Flashforward. Though interesting idea that he may find out during this Claire disappearance plotline.

I wonder whether we will actually hear frm Christian, as I find it very strange that he physically picked up Aaron. Is it really him or the Black Smoke, for what reason did he or the Black Smoke kidnapp Aaron and where is Claire?

This is an interesting development. I expect that we are building toward the Finalé right now and current events will culminate and possibly intertwine [as they often do] come the final two episodes.

I suspect Claire will die this Season and that could be the reason Jack could not bring himself to see Aaron in Eggtown.
