What's up with SpyBaby ?
I guess SpyBaby is Rambaldi's "Second Coming", remember, the reason why Sydney disappeared for 2 years. Rambaldi's DNA, Syd's eggs, blablabla... So, SpyBaby would be... Syd & Rambaldi's child, that would be logical, even if it's completely sick. Futhermore, "Prophet 5" is a Rambaldi project. So I guess Isabelle will be the 5th Prophet, that's why she is so special. But Prophet of what ???
I know, you're gonna say : "You freak ! It can't be ! How come she would have been pregnant of that thing ?". I guess it's gonna be something like "When Elena was at home, she inseminated me !".
I was thinking about the fact that everything regarding Rambaldi is said to be part of only one project. So, I guess the Rambaldi Device (you know, the big red ball !), the Sphere of Life, SpyBaby and Sydney are all connected... At the beginning I thought the Sphere of Life was conceived so that Rambaldi's consciousness can be implanted into SpyBaby's mind... Actually, we don't know anything about that Sphere (which was supposed to be Rambaldi's most priceless artefact). And I guess the writers just forgot about it !!!
