But she's not jealous of Buffy, she's jealous of Buffy's attention and sisterhood. In S7 Buffy thought the potentials were a burden they weren't competition for Dawn. And in #1 she didn't say she met Kenny on campus, I assumed then that he was a local boy, local to the castle that is as both Buffy and Leah had met him.

As I recall people were quite interested in the Immortal, if not at the what he had for breakfast level. He certainly turned up in a lot of fics. I don't do fic but I'm curious about this character everyone keeps talking about, partly for Dawn's sake and partly because he's symptomatic of all the fairytale elements that have crept into the show. I'm interested in whether he's a red herring or a significant player being hidden in plain sight. It's a mild interest comensurate with the prominence being given to Dawn's story but I rather like that there's a mixture of big and little mysterys, it gives the whole story texture.
