Symbolism of the two drinks
When Donovan visits the judge at his home he proposes keeping Abel alive for a possible trade. In the scene, he is holding two drinks possibly a visible foreshadowing for the trade to take place.
Later in the movie Vogel, the East German attorney, also holds two drinks in the same way -- matching the earlier shot of Donovan.
I'm wondering what is the connection Spielberg is trying to make?
