That's because she has no doubt. She's not like us. She wasn't made in the throws of passion. She was made in a lab, with thoughts of hate and vengeance. She was made, and trained, to take out people of great power, and did so before she ever hit double digits in age. People extremely hard to kill by anyone else, she has managed to get close to and end in a matter of minutes. Don't underestimate her because you think she's full of herself. It isn't vanity you hear in her voice.
Any one weakness you spot in her, she's already spotted twelve in you, in the same amount of time, if not less. I'm not even sure I could eat her, and she wouldn't somehow bring herself back together and burst out of my insides. She got infected with a disease that is specifically made to kill our kind, mine and hers, and she overcame it. To make a bad joke: Chuck Norris checks under his bed for her.
I don't know. I don't know them too well, to be honest. I knew Anna on the train, but I don't associate with the two that are here.
