Hurley sees Charlie in "The Beginning of the End". I thought it was just him going nuts-o, but then I remembered that another person pointed Charlie out to him. Plus, he slapped him!

Does this mean he's coming back? Will we get to see a bit more dead-Charlie? Will he visit anyone else? Or is he gone for good now?

Is it only Hurley that can see Charlie? How did that other man see him?

Who does Hurley have to help? How does Charlie know this? Is it just the wisdom that comes with being dead, or...?

And my most pressing question of all: Will he and Claire see each other again? Something kind of "Denny-Izzy-esque"? I hope so!
