[Shaking off his arm she looks back up into his face, feet planting back down, stubbornly.]
Zero, I've never lied to you. Least of all would I sit here and lie about something as important as this. Don't belittle my convictions. I've always been rock solid about those. Do you want me to say it doesn't hurt? That it's not painful?
[It's tearing her heart out. But Kaname's the one who's put her into a position she can't back out of. It would be different if he stopped and simply turned himself in, but she's not so delusional as to believe of such a childish fantasy.
She sighs, shaking her head as she glances away.]
I've made a lot of stupid blunders in the past. And you're right - until recently Kaname has only ever shown me a tender and loving side of him.
[From how dearly he cared about her as a child, to how he protected her into adulthood. Even now Yuuki doesn't doubt the sincerity of his feelings back then.
The difference is it wasn't enough.]
After getting anxious and scared I did run back home. And these are the results of that last meeting.
[She looks back up at Zero, challenging him to deny any of her words.]
I realize that Kaname is a liar, manipulative, and there's something dark inside of him. I've seen him injure you, Ruka-san, and there are countless others. As well as murder a dear friend of our household and has begun an assault upon the rest of the pureblood.
[Cutting the air with a hand.]
I'm his ex-fiance. And we were raised together as siblings. I have a responsibility to end this madness, and I can't do that if I have to worry over what to do with him after.
[Drawing up despite her height, she's serious, stance firm as she meets his gaze.]
You want to know what we're allies on? You had it right the first time. But I can't stop him by myself, Zero. I've cut the weights that held me back. It's fine for the two of us to work together now, isn't it?
