If I'm ever going to revisit this series I must ask.... I haven't watched this series in a long, long time but I don't remember was it ever really explained what was Number 6 in Gaius Baltar's head? Hallucination? Fantasy? Was Baltar insane? Was Baltar high? Apparently none of those, so what exactly? If it was never really explained, as I remember it, that is just weak. ”Yeah, we have this character that has been around for years, we don't really know what it is.... Except eyecandy”.
