Dirk tried to make it up to his children by bringing Zarjo home. I think he was beyond trying to make Ariah happy. He knew she would be unhappy about the dog. His only thoughts were for the case and the other woman. He was obsessed with her just as much as he was obsessed by the lawsuit. He put it all on the line and lost it all for a woman he tried to convince himself he did not love.

Poor Ariah. To have Dirk die in the water too. She may just be damned.
