In Nocturnal Animals, why didn't Tony, the protagonist of Edward's story, show any anger when he saw the rapists? He didn't even show much grief on his wife and daughter's death.
Moreover, he didn't look too interested to find the rapists. Was it to show that Edward isn't interested now to get his wife back after she left? But a part of him which he framed as the cop Bobby Andes wants to know the reasons why his wife left and wants to get her back.
As I understood it Edward's main motive was to take revenge on his wife who cheated on him because he was weak. But I struggle to understand how Tony's behaviour figures into the bigger picture there.
