Maybe KA didn't have any plastic surgery. That hasn't been confirmed by US Marshals. All they said was that she had a bandage on her nose. I think the plastic surgery comment might be conjecture. I'm thinking the bandage was part of her disguise, to cover up her most distinctive facial structure. Although it's not much of a disguise. Even the haircut wasn't that convincing. It was shorter, but still on the longish side, and the shade looks darker, but not dramatically so. Apparently, KA really couldn't part with much of her lovely locks, so I think she would be too vain to mess with a perfectly good nose. I did feel a lot of glee when the Marshal at the press conference described KA's hair as "uneven". A real hack job. I hope it hurt her pride.
