She hadn't been expecting that, and it was the only reason Crane had time to take those two steps. Not that the two steps would count for anything much if she pulled the trigger. A little less brain matter on the concrete, but the kitty cat wasn't on the cleaning crew, and it didn't really matter to her. But the fact that Damian actually told her to do it, that made her turn her head to regard him, her clawless fingers tugging on the tie she still held firm in one hand.
And she wanted to. Admittedly, she wanted Crane gone. It would fix things here, and it meant she wouldn't be under his care once the world was set straight again, once she ended up in orange and shackles for a stupidly romantic cause that wasn't even her own. And she was hurt, hurt at the way Iris had spoken to her, at the way the Bat always expected the worse.
Maybe it all lent to it, but she tilted the gun down toward Crane's shoulder, and she pulled the trigger. She didn't look, didn't watch, she just pulled and absorbed the ricochet with her shoulder. Bang.
