Hope you enjoy this one! I've currently started thinking about about two new projects that I'm going to work on alongside this so keep an eye out for new stories! One is going to be supernatural related and one will be avengers related.

A woman named Gloria is sitting watching TV in her house, and smoking. There are statues of angels on the desk next to her.

'Is this something to do with the angels?' Cas asked, looking confused.

'No. It was a spirit.' Dean replied. Sam smirked and looked down.

She comes across a program with a man talking about God, and she turns off the TV. The lights start to flicker, and then suddenly the TV turns back on, and the man keeps talking about angels and God. She tries to turn it off, but it won't turn off. Everything suddenly starts shaking.

'That doesn't look like a normal spirit?' John questioned.

'It was a strange one.' Sam said, with a smile.

She stands up and she sees a bright light behind her. She turns around and she can almost see a shape in the middle.

'Why is the spirit glowing?' Mary questioned.

'It was weird. He thought he was an angel.' Dean explained. Everyone else frowned.

Some time later, Sam, disguised as an orderly, interviews Gloria who is now in a psychiatric facility after murdering a man named Carl Gulley. Gloria claims that an angel told her to do it, and is completely at peace.

'That's so weird. Did the ghost possess her?' John asked.

Sam returns to a motel room, where Dean is keeping a low profile after his media exposure during the bank siege in Milwaukee. He relates her story, and Dean scoffs at the idea of angels. Cas frowned.

'It not such an outlandish idea that angels exist.' Cas protested.

'I'm sorry. It's not like we had met any of you guys before.' Dean said with a grin.

They proceed to investigate Carl Gulley's house, where they find a woman's skeleton buried. Sam later finds out after visiting the library that three people went missing, proving him to be a serial killer.

'So was the ghost one of his victims? Why would it get someone else to kill him?' John questioned.

'You'll see. It wasn't one of his victims.' Dean replied, making John more confused.

Overnight another murder takes place – a man kills a stranger and says an angel told him who to kill.

'So the spirit is pretending to be an angel?' Mary questioned. Sam nodded.

Investigating the victim's house, they find evidence on his computer that he was stalking a young girl over the internet. Dean discovers that both victims attended the same church - Our Lady of the Angels.

'So I'm guessing the spirit is using church goers to go after people who've committed crimes that they've gotten away with?' Mary asked. Dean nodded.

The boys visit the church and speak to Father Reynolds, who has nothing helpful for them, until he mentions his fellow clergyman Father Gregory was shot on the steps of the church. Dean thinks it may be Father Gregory, a vengeful spirit making people kill parishioners whose guilty secrets he knew. Sam is skeptical - he thinks it may be God at work, and reveals to a startled Dean that he prays regularly.

'I didn't know that.' John said, looking down. Mary glanced at him.

The boys return to investigate the church's crypt where Father Gregory is buried. Whilst they are in different rooms, an angel appears to Sam, and tells him he will be given a sign of someone to kill, someone about to do evil.

'Why did it go after you?' Bobby questioned.

'Mabye it knew I believed or Mabye it was completely random. I don't know.' Sam replied.

Sam and Dean get into an argument again, and Dean finally admits the reason why he doesn't believe in angels is because their mother also believed in angels, but that didn't stop her from being killed.

'It wasn't your fault.' Dean said, as Mary looked guiltily at him.

'I still made that deal.' Mary said, looking down.

Dean still thinks it is the spirit of Father Gregory, and suggests that they summon his spirit. If Father Gregory appears after being summoned, they'll know he is a spirit and not an angel. As they buy the supplies necessary for the summoning, Sam sees the man he says the "angel" wants him to kill, identified by a bright light around him.

'Please tell me you didn't kill him.' Cas said.

'Im offended you even thought that.' Dean replied and Cas put his hands in mock surrender.

Dean takes off after the man and tells Sam to go and perform the séance. Sam is interrupted by Father Reynolds, just as the spirit of Father Gregory appears. Sam is crestfallen, knowing that this means he is just a spirit. Dean stifled a laugh at the look on his face.

'At least I found out you were real in the end.' Sam said with a small smile.

Father Gregory is not malevolent - he genuinely thinks he is an angel. Father Reynolds argues with him, and manages to convince him of the reality. He finally puts Father Gregory's soul to rest by saying the Last Rites. Meanwhile, Dean is following the man Sam had identified, and stops him as he is attacking a young woman.

'She's damn lucky you followed him.' Jo said.

Dean chases him in his car, until the man's car nearly collides with a truck. Very coincidentally, a metal pipe from the truck perfectly impales the man, killing him. Back at the motel, Sam explains to Dean why his faith is important to him. Dean describes how the man died, and, against his better instincts, admits he thinks it may have been the hand of God at work.

'I doubt that. He was still hiding at this time.' Cas commented, completely ruining the moment.

'Thanks Cas. Thanks a lot.' Dean replied, rolling his eyes.
