How do we know the song is about the final cylon? Could it be about D'anna? Is there a connection between Gaeta's "three wishes" and her model number? Hasn't she too been "asleep" since being boxed? Perhaps Gaeta wishes for D'anna to "just one day wake," though he probably knows little about her situation. It was also odd having that one short scene where Baltar looks on at the suffering Gaeta from the screen in the hospital. Some strange connection there.
