Lol yeah, I get a bit carried away with the details. The specifics are all cut and paste, really. But my point in that theory is mainly that I think the end scene is a chronological order of events of her life time, including both what we see in the game as well as what we don't see.
But what are some other theories regarding the blue girl? I remember the one about her being Sabi's immune system, and while I can somewhat see the vslidity in that theory, I'm still much more sold on her being Sabi's mother, primarily due to the event with her stomach exploding, as well as the fact that she's seen in the hospital bed with what looks to me like a bun in the oven underneath the covers. :u
But when I say it that way, I can see that there's not much to suggest that she's Sabi's mother specifically.
As far as the school and Smile, I got the impression that the dominant "atmosphere" around Smile is that of a clique. All the students hanging around him, Sabi's inability to get to him, as well as her inability to get his attention, he seems very exclusive and somehow powerful in the school. Sabi found him kind of ominous and daunting, and tried join him, imitate him, or be more like him. His grin is him laughing *at* Sabi, particularly when she tries attacking him, saying "Idiot, you think you can hurt ME?" So I thought that him attacking Sabi in the basement was his way of saying "You're not welcome here, we don't like you, get out." In other words, I don't think Smile was being nearly as just and somehow helpful as he would be if he were fighting back a dangerous Rust.
And I'm not sure if I've suggested this theory before, but I thought that the Kaibutsu-Sabi's presence in the school, as well as the presence of the Kaibutsus in the school's lobby, suggested that they were some kind of higher up force in the school. Disciplinarians, maybe, or possibly a group of preppy snobbish kids, with the way that they all wear their neat little uniforms. But, connecting to your theory, Chesir, I do think there was conflict between them and Smile. Smile's some kind of a gangster, I think that goes without saying, which would put him in stark contrast with the preppy little Kaibutsu. Sabi saw the Kaibutsu as the one way to get back at Smile for antagonizing her. And I can't remember which was which, but aren't there multiple versions of the corrupt schoPost too long.
