I don't remember ever seeing Daala as sexualized. Happening to have had a history with Tarkin hardly makes her Darth Talon. And as for "still sexy in her 70s"... I don't see it. And even as a young woman, I don't think there's a picture of her in existence that shows skin below the neck. Come to think of it, Aurra Sing never really came across to me as sexualized either. Sultry, perhaps.
