Kagome is feeling jealous for the first time, and moreover, it's over another version of herself. It's interesting how the author can write about these feelings in such a natural and real way. Kagome's growth throughout the story is one of the best things about InuYasha. The encounter between her and the evil Kikyou is spine-chilling! I still don't know what the nature of this evil Kikyou is. But the narrative keeps getting better!
