I'm still thinking through this. I've been reading someone else's thoughts (Terese Odell - LOVE her Lost blog) and I agree with them. I don't think Aaron is one of the Oceanic 6. He could be but I don't think so. He wasn't on the passenger manifest so he wouldn't necessarily be called one of the Oceanic 6."
I read an interesting theory over on Television without pity that someone had heard on another board about who the Oceanic 6 are and why. I think it sounds good. Highlight the blank area if you want to know
*SPOILERS POSSIBLE*
At the end of season 2, 7 people went across the island to try to rescue Walt. Jack, Kate, Hurley, Jin, Sun, Sayid, and Sawyer. While they were on the other side of the island, Desmond blew up the hatch and everyone on that side of the island was exposed to radiation. From last weeks episode we know that people exposed to radiation have strange side effects when they try to leave the island and eventually end up dead which would explain why Desmond had problems and Sayid did not. Those 7 could leave safely because they weren't exposed. Sawyer said a couple weeks ago that he does not want to go so he stays behind. Aaron was conceived off the island and was not yet born when the hatch exploded and was not effected by the radiation which is why he was allowed to go with Kate. That makes the 6, Jack, Kate, Hurley, and Sayid whom we already know about and then Jin and Sun, plus Aaron though he is not officially one of the 6.
END SPOILER
