I was wondering about what Hurley said: "You're not supposed to raise him, Jack." Naturally, the first time I saw that I assmued he was talking about Aaron. But since I've started keeping my episodes on my DVR, I get to watch them several times while waiting for the next one. And the last time I watched this episode, I thought "What if he's not talking about Aaron".
Raise him could mean different things. The island seems to have the ability to bring people back from the dead. What if Jack could have the ability to raise Charlie from the dead? Or his father? Maybe Jack is desperate to go back to the island so he can use it to 'raise' somebody?
It seem counter-intuitive, but the more I think about it, the more I wonder if Charlie/Hurley was really talking about someone other than Aaron.
