Josie wasn't exactly in her element here, but she'd been well-trained by Division, and had kept sharp after she'd been let go. Which was to say she knew full well how to use being short to her advantage, ducking under the second man's gun arm, bringing herself up and into his shoulder, fingers digging against his side for purchase, smile going grim as she did much the same thing to him as she'd done to herself and Remy. Only this time she was pushing things out of place instead of putting them back in.
She made good on a threat she'd made on first arriving, to rupture someone's spleen. Of course, she ruptured organs around it as well, letting the man drop after a moment, stretching her fingers.
