In the season premier Miles accused Kate and Jack of killing Naomi. He told them he needed her body in order to see if they were telling the truth about how she died.

I wonder if maybe this would work for the "Adam and Eve" couple that Jack found in season one. I mean, I wonder why it was important to bring a character to the island who can talk to dead bodies and stuff if they weren't planning to address this mystery. I for one am still very interested in why they showed us this couple but have not mentioned it since.

I was actually wondering the same thing. It will be interesting to see what they have Miles do on the island.

I was wondering if maybe they know of Jacob and that's why Miles was chosen to be on the team.

ahhh...that's a good theory, I didn't think of that!

I was definitely thinking more along the lines that Miles would be dealing with Jacob at some capacity, whether or not he was sent specifically for that. But possibly other things too, such as Adam & Eve, and who knows how many other things, technically, could be talked to by the ghostbuster.
