You were on a case with Sam and Dean, a white witch has been cursing women whos husbands had cheated on them. They would kiss their husband and the husband would be killed by their deepest desire.. but if the kiss went on they were safe.

So when a girls husband had came back for her as her deepest desire Dean kissed her, making his deepest desire come after him.

You stood in the basement looking for the heart of the white witch that would kill the monster if you stabbed it, while Sam searched upstairs.

Neither you or Dean knew that Sam was about to stab it when another version of you appeared just in the outfit you wore when you first met Dean. “Hi Dean” your voice rang out in a sultry tone, only it wasn’t you.

Dean locked eyes with the other version of you then turned to you, he was about to say something when she groaned and turned to dust, Sam had stabbed the heart from upstairs.
