Danny, there are reasons why I kept you living in silence your whole life.
Reuven finally goes over to the Saunders house after Reb allows the boys to talk again. Reb explains, while using Reuven as a buffer, the purpose behind leaving a silence between him and Danny.
In the end both boys were allowed to do what they wanted with their lives. Reb gave Danny permission to pursue being a psychologist and Reuven fulfilled his wish to become a Rabbi. Danny shaved off his ear locks and beard to represent starting a new chapter in his life.
