Anna is a New Zealander. She's Viva's stepmother and also happens to be her sadistic PE teacher.
She's a bit of a loon and whilst she can seem like a total cow, deep down she has a pretty good heart. She's completely un-selfconscious and says the most ridiculous things while taking herself and her job extremely seriously. She's a terrible role model for the kids, too.
Her relationship with Rob is the most redeeming part of Anna. She really loves him and massively fancies him. With Rob, Anna lets her guard down and is almost likeable.
Her relationship with Viva is altogether more complex. They'd both love the other to accept them but they're both very proud and would hate to be rejected or show each other their vulnerable side.
