[Rationally, she sees Kira's point. She understand what she's trying to say. But she also knows Kira doesn't have all the details. So instead of getting emotional about it, she'll explain.]

You don't understand, Kira.

It's not about pushing her away, it's not about alienating her. I don't want that. But it's the only thing I have left.

I have to push her away. Because if she goes after Jerry? If, somehow, she manages to kill him before he kills her? She can be demoted. She can be stuck in this ship until she graduates and while we all know Allison is a good person, as you can see, she's not very good at listening. And I'm terrified that becoming an inmate would just destroy her even more.

So no, this isn't about me, it isn't about her protecting me. It's about me trying to protect her from herself.
