Julia comes in first. She was injured when Sunil pushed her and she says that he is worse. Treatment is not helping and she is no longer going to pay for it. Her husband will need to prescribe stronger medications for his father (or perhaps the houseplant).
Sunil continues to evade the questions. He sings in Bengali for Paul, a farewell song. When he says words in Bengali, Paul cuts him off, rather rudely, and tells him to speak English. Sunil asks Paul to keep an old cricket bat he's found; he might be tempted to use it to murder or maim or do something bad to Julia.
Paul is rather worked up during this session and he implores Julia to allow Sunil to continue in treatment. He further implores Sunil to keep coming. He offers to see Sunil pro bono, or to meet him outside the office for tea.
This episode requires that the viewer suspend disbelief in the realities of psychiatric treatment. It's a world with no psychiatrists, no hospitals, no rationale use of medications, no duty to prevent harm, and no sense that violence can come from a illness that one can't be talked out of. There is faith that treatment will ultimately lead to betterment, even when things are getting worse and the characters may not live through the day.
