There were very few things that got underneath Jasper's skin- four actually, her three ex-husbands and the man that killed Loki. Five, rules bothered her too. The ride here hadn't annoyed her too much since the seething banter between her and Lucifer was old hat, she was much more concerned about "interrogating" the fucker that killed Loki but she'd obviously gotten under both Lucifer and his boyfriend's skin and that made her smile.
Jasper was happy to be out of the car when they got to the surgery seeing as how confined spaces didn't suit her very well but her mood changed drastically when they stepped inside the room that housed him. She wasn't too thrilled that she was receiving sloppy seconds but at this point she'd have settled for anything, she was even feeling gracious enough to let them finish their argument despite the fact that she didn't know what Zane would have to say for himself, he was kind of fucked.
When Ben offered out the gun she didn't even think about jumping at the chance to snatch it from his hand but she did reach forward and take it if only too establish that she got Zane next, she had absolutely no intention of using that gun on him. She might shoot Lucifer but that was always an active risk and besides the point, it also wouldn't have been the first time. She looked at Zane for a few moments before she tucked the gun into the waistband of her jeans, "I want an I.V. with blood for him and something to cauterize with, I left a kit in the trunk. Why don't you be useful Lucifer for once in your life and go and get those? If someone has a car battery and jumper cables I want those too. NOW."
