Lines 81 - 84 are important because they show that a person is willing to help Jinsen's great aunt.
Jinsen wants to visit his father, but he cannot leave his great-aunt alone and has no one to help him with this task. This leaves him frustrated and without hope of living his own life.
However, between lines 81-84, we can see that Audrey offers to take care of his Great Aunt while he is away. This is very important because it allows him to visit his father and go after his own goals.
With this, we can say that Jinsen puts his family obligations ahead of his personal goals.
