Jack and Son seems to have a better relationship in this episode

This detail confirms for me that there are two alternate timelines going on. HOwever, since Sawyer knew Kate, that kinda discredits my theory. Does anyone remember the episode details this season enough to tell me if Jack's alternate timeline when he saw his son play piano was the same episode as the first or second episode when they were all getting off the plane?
