THREE

It was a bit of a debate between one and three. Three won out, because one has a bit of tension as if something is about to happen.

Two has a lot of energy in it, makes me think more of happy or joyful. :D

Four because I saw that scene at the end of the movie I still feel the exhaustion, relief and feeling of drained energy the scene gave me.

Three is just a moment caught by itself. There is nothing coming into that moment and nothing leading out of the moment. Just a moment where it is just the two of them with nothing else affecting them. Honestly, I think in their lives those are the moments of peace,when they can just be, no expectations, no worries. Though in my head in the next moment the tight focus would pull out and it will be time to work again.
