Inuyasha breathing heavily is also sweating, Kagome takes out her handkerchief and wipe of the sweat. Inuyasha asked her why she was crying. She answered that she was going to lose him. Inuyasha then ask if he could rest his head on her lap. She concedes to his request. While at that time, Inuaysha compliments her about how wonderful her scent was. She told him that he couldn't stand her scent, but it turns out that he was lying from the start when they met. For the way he was talking to her, Kagome's heart begins to pound. Just then the Spider head breaks into the room. He grabs Shippo to take the remaining shards, and then he swallows them. Nazuna believes that the spider head possessed her master, but it was a trick from him. She attacks him but it was no used. She was her father to forgive her to trust him. She drops the sword. The Tetsusaiga is caught by Inuyasha who is okay, and admires Nasuza's determination. The Spider grabs him instead, but Inuyasha has a smile on his face; the sun is rising, allowing Inuyasha to return to his normal form. With his powers, and those of Tessaiga back, Inuyasha easily dispatches the Spider heads. They leave by boat and Nasuza thanks for their help and remembers to trust the demons a bit more. While on the boat Kagome thinks about what happened that night, and wonders if Inuyasha actually meant what he said to her, but his attitude is back instead of his kind words to Kagome. Shippo wants a break because of his seasickness. He then throws up on Inuyasha which grosses him out.
