Disclaimer: I do not own Lucifer or anything else that looks familiar.
Lucifer goes out to the garage to look for his car. It isn't there.
"Maze, where is my car?" he calls.
"You don't need to drive," she says without looking up.
"What do you mean I don't need to drive?" he asks indignantly.
"Did you know that car accidents are the third-leading cause of otherwise healthy mortals?"
"Why would I know something like that?"
"Well," she says, "now that you're maybe mortal and can definitely be injured, I would think you would pay more attention to these things."
"So you are just going to take my car?" he asks incredulously.
"Yes."
He sputters. "Maze, you cannot do that."
"What are you going to do to me?" she asks sultrily.
"Why, punish you, you bad girl," he answers. Then his voice hardens: "But I expect to see the car in the garage in the morning."
IN the morning, he goes out to the garage, and instead of his car there is a mom monstrosity where his car used to sit.
"Maze," he says much more patiently than she deserves, "I thought I told you to put my car back."
"I put a car back," she says. "This car is far safer than the other one, and it will not tolerate you driving as riskily as you normally do."
"I cannot go out with a car like this!" he cries. "What will do that do to my reputation?"
Maze does not care about his precious reputation. She knows that he could go out any time and buy a new one, bypass her altogether. But she has his precious car hostage, and she knows how long it took for him to find it.
"It's either this," she says, "or I let the mechanics at the other one."
He understands why she is doing this. If he didn't, she'd be meat right now, probably being roasted on a fire. (Though that's less his style now than during his thirst for blood phase.)
"Okay, fine," he says exasperatedly. "We'll go car shopping tomorrow. Something I can actually go out in and something you approve of also."
She considers. She's actually fond of the, leave this, plan. It would probably encourage him to drive less, which would be altogether safer. But he'd probably go without her if she pushes her luck. "Deal," she replies.
She tips the dealership heavily to only show them cars that she has pre-approved for safety and to temporarily get rid of all other cars on the lot. They are able to be tricked out and don't look terrible, so she thinks it will be fine.
Lucifer knows what she has done, and he glares at her heavily. "What kind of selection is this?" he asks her and the receptionist.
The receptionist stammers and runs away.
"We agreed we'd pick something out," she says calmly. "I thought I'd save us the trouble of arguing. If you don't find something, we can go elsewhere."
This is his preferred dealership, so he'd rather not.
"Are you embarrassed to be seen in something like that?" she asks. She points at a tricked-out car she thinks he'd like.
"What? Ooh… where did you come from? No, of course not."
Let it not be said that Maze does not know Lucifer.
AN: So there are options to continue this story if you are interested, as Lucifer does a lot of dangerous things.
