My biggest question is why was Aaron still a baby at the end? That didn't make much sense.
Yeah, that confused me at first too, but I think the explanation is that they all reunited in the form that they knew each other during the island years. Like Aaron, all the people who survived the final confrontation with MiB presumably lived for many years after that, but they didn't show up in the alt timeline/purgatory as elderly people; they showed up in the form they had on the island. What confused me, though was how they all survived the nuke at the end of last season. I mean, if the nuke had split the timeline, as we all thought, that would be one thing, but if the only earthly reality was the one on the island, then why the heck didn't the nuke kill everyone? Hell, it didn't even kill Juliette, who was sitting right next to it! (Remember, she had a few final words with Sawyer after it went off.) And speaking of Juliette, what was she talking about when she said, "It worked," after the explosion? It obviously didn't!
Basically, I think the writers finished last season planning to use the alternate timeline concept, but changed their minds after a while and went with the religious angle instead. I suspect they did so because they wimped out on explaining how the island "worked" in sci-fi terms and figured that a religious approach would allow them to claim it was all about a purely spiritual journey so no real explanation was necessary. *shrug* I found that really disappointing, but I did love the awakening/reuniting scenes in the alt timeline/purgatory. I would have preferred it, though, if they'd left it as an alternate timeline in which their memories of the island "leaked through" so they could have their happy lives together.
