A friend sent me this :SPOILER! People we all missed this--the last scene .. Jack in the black shirt, the speech, the wink.. Rebecca's glowing in the light face-- jack was already dead! he went out the night of the fight when she went up to bed, died that very night, in the morning when she came to look for him -- he was already gone. This was the "sixth sense movie type" of scene!! The writers knew exactly what they were doing. We saw Rebecca go to bed the night before.. that was it. Even in the very last scene when he "leaves" she is staring out the window toying with her necklace-- not looking at the door - this is what has never been done on tv before.. (you'll see in the scene earlier with him in heaven with William laughing he has on the red plaid shirt, same shirt he was wearing the night of the fight. Clean shaven jack sitting on the sofa in the black shirt in the morning - Jack was a ghost. The writers knew we would be mad but will show how Jack died in the very first episode, hence it was all still the night Kate told him to go after mom. Thoughts?
