"Well ... because I'm not asking you to?" Setsuna's face is grimly self-assured, a firm core of unswerving confidence meeting Catra's laughter like she saw it coming and had already decided to shrug it off. But she raises her eyebrows with the open question.

"Call me selfish, if you need to ... every promise we make is just as much a promise to ourselves, in the end. That's why anybody who breaks one, breaks their promises twice over when they do. And having a promise broken hurts a whole lot, even if you're the only one who believed it was one." She keeps her hand up, smiling - not exactly serenely, but undeterred. "And," this is the worst part to see, probably, because there is a genuine lack of fear in her face, only a gentle and earnest acceptance, that she must've had to learn because it doesn't seem like something she ought to be capable of doing on her own, "I believe in you, anyway. So you can believe me later, and take it for what it's worth now, okay?"
