See, I like flirty!Lee when he's asking Kara to dance in "Colonial Day", or slipping on his suit jacket at the Death Wall in "Islanded...". Or Lee in all of his scenes with Dee before the Quad issues. And decisive!Lee when he's mutinying against Tigh or standing up to D'Anna. Actually, what it comes down to is, I always find JB attractive (especially his natural voice, yes), but I don't always find him sexy. Sexy's a very subjective thing, though, especially with me.

As relates to Shirley, though...actually, that aspect hadn't crossed my mind. I was thinking of something else entirely, though your parallel does make sense now that I think of it.
