[Caitlyn can't fathom why Hirasheri would call someone else, someone she's referred to as her sister, a 'used fool.' She also can't fathom why Hirasheri is threatening her. She's trying to get to the bottom of this, she means to help...

But she tries to pull backwards, ready to pull out her gun should the woman attack but not going for it yet.]

I'm not your enemy. What happened to Massarir was wrong. [She's very deliberate about using the name, hoping that Hirasheri will remember that Massarir was a person, that she'll understand that Caitlyn sees her as a person and not a faceless monster or a useless fool.]

But if you do this, if you kill more of us, it will only lead to more violence. More of your sisters' lives lost. Tell me who killed Massarir, and I'll make sure that he won't hurt any more of your sisters. I promise.
