I believe that she felt slighted that they didn't come to a unanimous verdict, like she isn't important enough. If she'd gotten death, she could have wallowed publicly in her martyrdom. And if she'd gotten life, she could have basked in the "love" they showed her. This way, she hasn't really come out seeming very interesting. Now she'll just have to wait around at Estrella, try to remember what her last version of everything was, and face a jury who probably has her number already. I think she's much more likely to get a unanimous death sentence the second time around.
