AVClub: TV show crossovers are an odd beast. It’s a weird concept, isn’t it? When a super-hero appears in a different super-hero’s city, that makes sense; heroes live in a shared world. But we don’t make that assumption with TV shows, or at least I never have. It’s especially odd here, given that Bones so clearly follows a skeptic’s philosophy. I’ve only seen a handful of scenes from the series before this week (I did watch both parts of tonight’s two-parter), but that was more than enough to give a clear sense of how Dr. Brennan and Booth’s reality works: crime happens, science picks up the pieces.
