Ten weeks ago, on Galactica, the poundy drums were in full force. Sharon Valerii, having been in hack after shooting Adama at a really inconvenient time, was hustled down a corridor. The faces of her former friends and compatriots were angry, but she kept looking at them all. Cally ran forward, twisted with rage, and shot her stupidly in the abdomen. In the birthing tank, now, Sharon's eyes twitch. She remembers, downloading: kissing Chief Tyrol, waking up all wet with no idea how she got there, many naked Sharons, the word "Cylon" scrawled across her locker mirror, a gun in her mouth, Chief coming to her post-suicide attempt, shooting Adama, his hand outstretched, screaming in the brig, Tigh with a gun to her head, and sitting with the betrayed Chief in hack. The drums stop, and Chief says, disgusted: "I'm not a Cylon. You're a machine; I'm not." That's her question, the entirety of her question. The whole Brokeback Mountain of her Season 1 storyline has led Sharon to this download: she is the line between the human and the Cylon, the blurring of her two identities, the love of Chief. Put her together with the Six above, and something magical might happen. The drums continue, and again, Sharon dies, Chief holds her, a drop of blood splashes on the deck.
