She looked 16 because she was only 57, which is quite young for a vampire, and vampires age slowly. What I thought was odd about her is what was she replaced her Vampirism with? Otto-photography, Melitida (sp) has coffee, Lady Marolotta has replaced blood with politics. I thought for a second, that she'd obcess over men (because of what she'd thought about Carrot) this would make sense in the sense that in vampire terms she's a 16 year old girl-getting crushes. It would also lead to an interesting conflict between Angua and her. In that she'd be obcessing over Carrot, who's Anguas. But if she stopped obcessing over him, she'd start obcessing over blood.I think that would have been ok.
