An overwhelming urge to punch this boy in the face flared up in Kacey as she [s]glared[/s] stared at him, waiting for him to finish his rant, while she simultaneously planned her counterargument. Her fists clenched, and it took most of her self control (albeit, there wasn't much left after the earlier events) to remain calm while she listened. She wanted to snap back at him, lose her control and yell at him like she'd been having people yell at her lately, but instead she forced all of her arguments down. She had to admit his argument wasn't completely invalid, and that just pissed her off even more. God dammit she really did not want to have this conversation right now. 

After  a very long pause, she bit the inside of her cheek, a habit she had formed over the years that was a telltale sign that she was pissed off but trying to consider her words carefully, she stepped closer to him and kept her voice low. 

"You know what? Fine, she can come on the next heist. But if she screws up and gets herself, or someone else killed, I blame you. God knows I really don't need to lose you because frankly you do good work, but if it comes to the safety of the rest of the gang or you, I will choose the gang. It's my job to keep everyone safe, and I seem to do that job fairly well. Yeah, I'm a shitty people person, and I know you and your sister hate my guts, but at least y'all are alive to bad mouth me behind my back. But you get one chance to prove that your sister can follow orders in the middle of a shootout, and I won't take responsibility if one or both of you comes back tossed over a saddle." Kacey stated, honestly surprised that she'd managed to soften what she had been planning to say as much as she did. The original idea of what she had been planning to say had been something along the lines of her killing him herself, but she was glad she went a different direction. 

"And don't tell me what I should or shouldn't do. And definitely don't bring my sister into these conversations, because you don't know shit about it. Now leave me the fuck alone." His comments about Laura had hit a soft spot that had taken a beating that day. Her sister was mad at her, she felt guilty, she was pissed off, her dead kid's birthday was a few days off, she was upset, and had reached her limit. An emotional meltdown was on the horizon, but she was trying to keep it in check and this conversation was not helping.
