He is, but in Cally's state, she wasn't thinking about that. The only things that mattered to her was her child and the fact that her husband was not what she thought he was. But, I have to agree in part with guitarfan01, that Tori is like the new Six. Well, not so much Six, as much as she is willingly forming to the known stereotype of a humanoid Cylon; cunning, deceiving, sociopathic, even murderous. Personaly, I think that the most interesting thing that RDM could do right now, after Tori has murdered Calli, and Tyrol has lost his wife, would be to reveal that the four are just human after all. Just to show them that even humans are capable of doing things that otherwise unhuman.
