It was a quiet day in the bunker. There were no weird police reports, no possible cases, or literally anything else going on. You decide to take this opportunity to go and really explore the bunker. You had been living there with the boys for a few years now and never had the chance. You found a lot of bedrooms, a couple of pantries holding an extensive assortment of spell ingredients. But the room that got you the most excited was the last one that you found, the garage. Of course, you've been in the garage before, but all the lights, except the one over Dean's parking spot, were off, so you never really saw the whole thing. But when you flicked the switch by the door, you found the garage filled with at least a dozen or so beautiful cars from the previous occupants of the bunker, plus the Impala. One, in particular, caught your eye, a cherry red 1959 MGA, in pristine condition. You run over to it like a giddy school girl, trying the door to see if it's open, and it is. You look for the keys, and they are in the sun visor. You are really excited now, planning on taking a little joy ride. You put the keys in the ignition, turn it, and nothing. You try again, and still nothing. Biggest bummer ever. You get out of the car to check the engine. You pop the hood to see what's wrong with her. Upon inspection, you see a cracked cylinder head, signs of an oil leak, and a blown gasket. You take a look around the garage, and you, surprisingly, find all the parts you need plus oil to fill it once the leak is fixed, so you get to work.

Meanwhile, in the library, the boys are looking for possible jobs when Sam realizes how long you've been gone.

"Hey, where's (Y/N)? She said she was going to explore the bunker, but that was like two hours ago. She should be back by now."

Dean looks at the time and realizes his brother is right.

"I'm sure she's fine. She probably found something interesting."

"I don't know, Dean, there are a lot of rooms even we haven't been in. What if she found something dangerous and something happened to her."

Dean starts to get nervous,

"I guess you're right. I mean, look what happened with Dorothy and the wicked witch, let's go find her."

The boys checked all over the bunker until finally, they got to the garage, the last place they would expect to find you. They hear music coming from inside and the unmistakable sound of metal hitting concrete. They slowly walk in and see your arms deep in the engine of a car, covered in grease from your waist up. You didn't notice them come in. Dean tried clearing his throat to get your attention, but the music was too loud. So he kicked the metal garbage can that was next to him, making you jump and hit your head on the hood of the car. While rubbing your head, you turn your music down and turn to see the boys with surprised looks on their faces. Dean says with a smile,

"Hey there, little grease monkey."

"Hey, what's up? You guys find a case?"

Sam chimes in,

"No, you were gone for like two hours, we started to get worried. Honestly, we never expected to find you down here."

"Why? Because I'm a woman?" You respond, pretending to be offended.

"No! That's not what I meant..." Sam starts turning red. You laugh,

"Sam, relax. I'm just joking." He gives you a nervous smile, you and Dean laugh at him.

"But what are you doing in here?"

"Oh! Well, I found this place," you pat the car, "found this beauty, and wanted to take her for a ride, but she wouldn't start, so I popped the hood, saw what needed fixing, and started working."

"Ok, new question. How do you know how to fix cars?"

You smile at Sam.

"My mother was a hunter, as you know, but my father wasn't. He had a normal job and took care of me when she was away on a hunt. But then he got sick, and after he died, she needed someone to take care of me cause she didn't want this life for me. So she would leave me with her brother who owned an auto repair shop, and once I was old enough, he would let me help him, and he taught me how to fix cars, re-build them, pretty much everything about them. So I worked there while my mom hunted monsters, that is until she died then I learned everything I could about monsters so I could find the thing that killed her, then that's when I met you guys."

"So let's see how good you are cause I've tried to fix that one and got nowhere."

You give Dean a smug look, close the hood, get behind the wheel, turn the key, and the engine roars to life. You smile at Dean.

"Wow," he looks at you genuinely impressed, you give him a wink, "maybe you can help me out with Baby sometimes."

"Really?!"

"I said maybe!"
