Okay, well let me just put this out there:
SPOILERS--IF YOU HAVEN'T SEEN THE SHOW AND DON'T WANT TO KNOW, JUST STAY OUT OF THE THREAD, OKAY?!
Alrighty then...
So, Tyrol. Yeah, the conversations with Cavil are interesting. Does he realize Tyrol is a Cylon? The seven numbered models, from what I understand, do NOT know. Is Cavil somehow the exception? Being the #1 model and, presumably, the earliest, that could be. Not sure.
But Tyrol being outed has some other interesting implications. Assuming I understand the "rules" correctly, by process of elimination, Callie is NOT a Cylon because Cylons cannot have children together. And that also means Hera is not the only human/Cylon in existence. But the Cylons likely have no idea of this.
Is Tyrol more affirmatively outed at any point in time? I mean, I know it should be obvious after this episode, but his there anything more conclusive done down the road? I don't want to know what it is, just a yes or no.
Regarding Three, I thought she might be referring to Saul Tigh. The apology and "what have we done?" attitude makes it clear that she feels the Cylons wronged whoever of the Five she was talking to, and Saul with his missing eye seemed the likeliest candidate.
But also interesting about the "you were right" comment. It's hard for me to imagine what she meant. But here's just an abstract thought: One thing Baltar has said recently that seems of some significance was his comment about the Hybrids, that nothing they say is just gibberish. I wonder if Three may have been acknowledging his opinion of the Hybrids, which would then make some clue that the Hybrid dropped become important. Hmm...
