Benmer, when you flipped that image, it made me think...I'm more than ever convinced that the "flashback" was all in Des's head - no time travel involved. The first shot in Widmore's office is a wide shot, and Des is clearly sitting in the right-hand chair, with the model boat and whiskey on Des's right. But when they show the first shot of the painting, Des is sitting the left-hand chair, and the painting is on his right - what happened to the whiskey and the boat? In later shots, the boat and whiskey are back on the right, and the painting is on the left...you really need to watch this scene again, if you can. The room definitely flips throughout the scene, which makes me think the whole thing is happening in Des's head, as the details keep changing.
