The moment she shouted, Celty knew she shouldn't have as it wasn't really what she'd meant to do. She drew back and caught her tongue before she spoke on reflex again, trying to keep her restraint. Mikado wasn't Shinra, and he definitely wasn't used to her shouting or saying anything either. Her own feelings were usually so easy to keep in her mind too that just blurting them was so...

...not her.

Before she could sort not only her word choices but herself out, Snow suggested them sticking together which really seemed to solve everything that she was worrying over when it came to the younger boy. If someone like Shizuo was with him, someone who didn't explode like Shizuo, then Mikado really didn't have anything to worry over save for keeping out of the way in a fight. As for herself?

I can fight, you know... she eyed Snow, a little defensively, before realizing she hadn't said as much and, picking her words this time, spoke calmly, "I do know what I'm doing."

And Mikado should know it. She looked to him, still frowning a bit, but finding she had the unpopular opinion in all of this. Eventually she smiled just a little and agreed, "I don't mind. As long as you're not on your own. You're... not a fighter..." At least not in a way that mattered in this place.
