The Devil is Coming

This story is basically a what if.
Dean sells his soul to save another Hunter...excuse me Huntress. Dean fell for Elle after he heard her heartbreaking story, and she saved Sam when Jake was going to stab in his spinal cord but instead of hitting Sam's spinal cord he hit Elle's. And Dean sold his soul to bring her back little did he know that God was working on doing that himself so Elle woke up with her memory of what happened so she told Sam to let her go so she could barter her soul for Dean's.
But she lied to Sam and Dean that it didn't work so they wouldn't worry about her. She leaves them when her year is almost up but comes back to that church with Lillith and Ruby and Sam and Dean and Dean is wondering why he hasn't been having hallucinations yet and then realizes what happened and yelled at Sam "Elle traded her soul for mine didn't she Sam?!" Sam was confused, "That was her plan but she told me it didn't work so I just left it alone." and they both realized she lied to both of them so they were hunting the huntress.
