Lazarus (Jack Kline x Reader) Oneshot

Jack was dead, but his body was moving. Every moment you saw the dark, twisted being possessing him felt like you were trapped in Hell. Your brothers had become trusting of the demon, Belphegor, allowing him to join your team, but you were not so easily fooled.

Taken place early season 15. Changed some of the events to fit the story.
I would appreciate it if you voted up. :)
