I'm not yet 100% sure of the Dante+Beatrice = Grissom+Sara thing. When I read up the info on Dante, of course I jumped to this conclusion at first. But with more time to tink about it, I'm not so sure anymore. We don't know about the relation between the title and the content. For all we know, the victims' names could be Dante, Virgil and Beatrice. Secondly, I don't know how they could bring her back in the context of "travel through hell, purgatory and heaven" without making it a major soap opera (=jump the shark) moment for CSI. What I'm pretty sure about is the amount of passed time. Dante's work takes place on the Easter weekend, which is 2 weeks before the episode airs. I think the episode will take place around Easter, so Sara has been gone for four months (maybe a flashback or mention of Christmas holidays together *thud*). So in my opinion, the writers didn't say "Hey, Sara's back, but she was gone only five weeks because on CSI it's only January." I think I need more details about the case to form an opinion if Grissom's Divine Comedy really means "Take the plot of Dante's work and replace Dante with Grissom, Virgil with some guy, and Beatrice with Sara"
