Significance of mysterious characters like Taxi driver and Nurse?
While telling Aomame about the way through expressway taxi driver said:
“ Things may look different to you than they did before. I’ve had that experience
myself. But don’t let the appearance fool you. There is always only one reality.”
This sound weird at first but as the novel progress it seems perfectly true. The job of taxi driver was to send Aomame from 1984 to 1Q84.
Nurse Kumi Adachi is another mysterious character in the novel. She met Tengo in town of cats. She invited Tengo to her room and then they smoke hashish. Nurse told Tengo that she died once and then comes to life again. After smoking hashish she said to Tengo:
“ When morning comes you will be leaving here, Tengo.
Before the exit is blocked.”
It was a message for Tengo. At the end when Tengo had his doubts about meeting Aomame at the slide he thought about what Kumi had said. He made up his mind as Kumi had indirectly told him to forget about the past and head towards future before it is too late. So she played an important role to send Tengo to another world.
