Kagome was completely offended by the idea that Inu-Yasha had been reading her journal. Despite this she found herself a bit torn over whether it was right (or good) for her to leave. After all, he doesn't know how complicated people have become. 'Nonsense! I'm sure people kept journals back then,' she argued to herself.
Suddenly Kagome realized she had forgot her backpack in the Sengoku Jidai! She rushed back down the steps and hopped back into the well just to hit the stony ground rather hard.
She sat there for a moment, confused as to why she didn't pass through into the Sengoku Jidai. She felt for her necklace- no, she didn't leave the jewel there too. Was Inu-Yasha really that mad that he would've blocked the well on her? She started digging. Maybe that would work? But it didn't. She started to worry about what she left in the Sengoku Jidai that she wouldn't want Inu-Yasha to get into…
No, don't think about that. How was she going to keep him from getting killed if she couldn't get back to the Sengoku Jidai?
"What? Duh, Kagome, he's part demon, I'm sure he can take care of himself. I guess that he'll come for me if he decides he needs me, then."
She left it at that, and set out to catch up with life at him in her own time.
