Okay. Having re-enacted the Sad Finale Hug last weekend I am now even more upset about that scene and here is why:
Hugging a person who you desperately want to hug you back and not getting any response is the worst feeling in the world.
It might almost have been better if Stan had pushed him away, but as is Ford is hugging his brother for the first time in over forty years and Stan just doesn’t move. Doesn’t react. It must be like hugging a statue.
And we know that by the time they get back to the Shack that Ford doesn’t have any hope that they can fix it. Not that he would have had much to begin with, but I think there must have been a glimmer, and I think it died when he was kneeling there crying into Stan’s shoulder, holding on for dear life and wishing with everything he had that Stan would return the hug. Just raise one arm. Just lean into it a little.
But he does nothing.
