Jack back on Oceanic 815 with Rose, Benard & Desmond?! + less booze + blood on his neck

We're back and "LA X" was a hell of an episode. We start with Jack, back on Oceanic 815. While many things are very similar, there are some distinct differences. When flight attendant Cindy Chandler gives Jack extra alcohol, this time he gets just one bottle instead of two.

Also, when the plane hits turbulence, Rose comforts Jack instead of the other way around. Jack is desperately gripping his armrest. During the entire scene, Jack seems shell-shocked, like he knows something is not right but he can't quite place it.

After the turbulence passes, we hear the familiar sound of Captain Seth Norris' voice. Jack gets up and goes to the restroom where he notices a spot of blood on his neck, which he wipes off.

And then the kicker. When Jack returns to his seat, he finds Mr. Desmond Hume sitting on the isle seat. Desmond is reading the book Haroun and the Sea of Stories by Salman Rushdie. Jack clearly has a memory of Desmond, but is it from the track years ago or from the island? In this reality, did Jack and Desmond ever meet at the track?

In the background of the scene, we can also see Jin, Sun, Locke and Frogurt.
