Understanding Altan’s childhood trauma helps Rin develop empathy for him, and particularly for his drug use. Opium, she sees now, can help a person reach the gods—or it can just provide a much needed break from one’s pain and suffering. Notably, Rin understands that what Altan plans to do is a bad idea. On some level, she realizes that Jiang—
