Quote #4
"You have childrens?" Manjiro asked.
The captain shook his head, coughed, and said, "No." He paused. "No," he said again.
"You have no childrens; I have no father." Manjiro said, and their eyes met for a moment.
When Manjiro left the room soon after, he tried to identify what he was feeling. He was no longer afraid. He was no longer angry. He was, perhaps, a little amazed. A little surprised. And maybe even a little bit happy. (2.6.50-52)
This is the first father-son bonding experience Manjiro has with Captain Whitfield. It almost sounds like first love, doesn't it? And it is—just of the familial sort.
Quote #5
"I have three sister and one brother. I have no mother, no father. My one brother older but he weak. I take care family." He stared down at his teacup, tears trembling in his eyes. Of course, he was not taking care of his family. (2.6.33)
Here's the reason why Manjiro is so concerned about his family. Not that he doesn't have a cultural reason for his familial ties, but it's clear that there's a practical reason, too: He's the only one who can work.
