I don't mind a good PWP, but I'd also be curious to see Helo/Sharon fic exploring serious stuff...they'd be a good pairing for thinking through what a Cylon really is and the boundary between Cylonicity and Humanity. I was just re-watching Home1 and although Sharon tends not to talk theology as much as her fellow Cylons she's really, really familiar with human mythology and can quote human sacred texts by heart. I wasn't happy with where Athena's arc went in canon, and the way she was defined purely by her motherhood, and that horrible scene where she kills Natalie, but I think there's a lot of room to do interesting things with her in fanfic.
