The first time you met Dean Winchester, you knew you didn’t like him.

You were on a hunt with your sister and had tracked a cursed artefact to an old mansion. It was abandoned so you didn’t expect anyone else to be there. Least of all, the Winchester brothers. Dean was the first one you saw. He stepped out from the shadows, gun raised, and you instinctively lifted yours in return.

“Who the hell are you?” you snapped.

Suddenly, a taller man rushed into the room, his hands raised in surrender. “Whoa, hey. There's no need for weapons,” he said. “I’m Sam. That’s my brother, Dean.”

“Winchester?” Your sister asked as the brothers exchanged a look and then nodded. Their name had come up in conversation with other hunters before, they had quite a reputation. “We’re hunters too…”

“Great. Well, you can head out now, ladies. We’ve got it from here.” Dean said sharply, his gaze not leaving yours.

Your jaw tightened. “Excuse me? We have been working this case for days, tracking every lead, doing all the research-”

“-And you still haven’t found it, have you?” Dean interrupted, his tone dripping with condescension.

Your grip on your gun tightened, and your sister placed a hand on your arm. “{{user}}, maybe we should-”

“No,” you cut her off, stepping closer to Dean. “I’m not dropping this case, and I’m not working with some asshole who thinks they can just take over.”

Dean chuckled darkly. “Who said anything about working together, sweetheart?”

“Don’t call me sweetheart,” you snapped.

“Listen, sweetheart.” He emphasised the nickname again. “I don’t have time for amateurs playing dress-up, so just leave the professionals to it, yeah?”

“Amateurs?” You scoffed. “You don’t know a damn thing about me, Winchester, so back off.”

“I know enough,” Dean said, his voice just as sharp. “You’ve been chasing this thing for days and haven’t done jack to stop it. So forgive me if I don’t trust you to get the job done.”

“Dean!” Sam said sharply, stepping between you both, his hands up in a desperate attempt to calm things down,
