Dean comes to consciousness - buried in his own grave.
'Is this part of your hell torture?' Mary asked.
'Nope.' Dean replied.
'So how did you get out?' John asked.
'You'll see.' Dean answered, giving Cas a small smile.
He digs himself out, and emerges in a field. All the trees nearby have been felled, radiating out from his grave.
'Did that happen because you came from Hell?' Jo asked and Dean nodded.
'Are you a zombie or something?' John asked, worriedly. Dean chuckled and shook his head.
He walks until he finds an empty gas station, where he eagerly drinks some water, and then examines himself to find no sign of the hellhound attack.
'So there are no scars or anything?' Mary asked. Dean shook his head.
However, there is a large handprint burnt into the skin of his left deltoid.
John and Mary frown as they tried to figure out what it is.
Dean grabs some more water, candy, and a copy of Busty Asian Beauties.
'Of course that's what you grab just as you get out of Hell.' Sam said with a smile.
'Obviously' Dean replied.
As he prepares to leave, a TV and radio switch on. Thinking it is a demon, Dean pours salt along the window, but he is soon crippled by a piercing sound that shatters all the glass in the area.
'What the hell is that?' John wondered and Cas looked at Dean guiltily.
As quickly as it started, whatever it was stops. Dean phones Sam but gets no answer, and Bobby hangs up on him, not believing that it is him.
'Sorry I didn't believe you.' Bobby commented.
'That's alright. You're naturally suspicious.' Dean replied.
He steals a car from the gas station and takes off. When Bobby finds Dean on his doorstep, he assumes it is a supernatural being and tries to kill him. Dean tries to prove his identity by cutting himself with a silver knife, and they embrace.
John and Mary smiled and relaxed slightly.
Bobby then checks whether Dean is possessed by dousing him in holy water. After that, he believes that it is Dean, resurrected from Hell. Bobby tells Dean that he hasn't seen Sam in months, but Dean tracks Sam using the GPS in his phone and finds him in a town near the place Dean was buried.
'That's lucky.' Mary commented, looking slightly suspicious.
When Bobby and Dean arrive at Sam's hotel room, the door is answered by a scantily-clad woman.
'Seriously?' John questioned, looking surprised. San just looked uncomfortable and sank back into his seat.
Sam also attacks Dean thinking he must be a monster, but when he realises it's Dean, there is a tearful hug.
'That's adorable.' Cas commented, sarcastically.
The girl asks whether the boys "are together," but Sam says they're brothers.
Everyone except Sam and Dean snicker.
The girl takes her leave of them. Sam promises Dean he didn't make a deal to get Dean out of Hell, or use his powers. In fact, he is upset that he was unable to save Dean. He tells them he was following some demons who led him here.
'That makes more sense.' Mary commented.
Bobby suggests they visit a psychic to see if they can find out how Dean got out of Hell. Bobby and the boys travel to meet Pamela Barnes, an old friend of Bobby's.
John and Mary laugh at Dean's attempt to flirt with her.
She starts a seance to reveal who saved Dean, and contacts someone called Castiel.
'So you got him out of hell?' Mary asked. Cas nodded.
'Thank you.' John said.
'I was ordered to but your welcome.' Cas replied.
But when she sees him in her mind, her eyes are burned out, rendering her blind.
Cas looked away from the screen guiltily.
Later at a diner, Dean and Sam discuss what to do, when the waitress reveals herself and the other people in the diner to be the demons Sam is looking for.
'I thought that they would turn up at some point. Jo said, worriedly.
She threatens Dean but doesn't take any action, and doesn't seem to know anything about his escape from Hell. The boys leave, although Sam wants to exorcise the demons.
'We probably should have done that.' Dean agreed.
Later that night, Sam sneaks out while Dean is asleep and heads back to the diner.
Mary and John looked confused. Sam looked away guiltily.
When Dean wakes up, he again hears the piercing sound that he heard in the gas station.
'So that was you?' John asked.
'Yes. I thought that Dean wouldn't be affected by it.' Cas replied.
Bobby returns as it stops, and Dean convinces him that they need to summon Castiel. He calls Sam, who lies about being at the diner, and tells him he and Bobby are getting a beer.
'Why were you lying?' Mary asked, confused. The look Sam gave her told her that she would soon find out.
Sam goes into the diner and finds one of the people who was possessed dead with eyes burnt out. The possessed waitress, although also blinded, attacks Sam, and warns him that everyone is going to die. Sam lifts a hand and exorcises the demon using only his mind.
'How did you do that?' Mary asked, looking concerned. Sam didn't answer.
As he finishes, the woman who was in his hotel room earlier enters. It is Ruby and Sam has been working with her to develop his powers. He tells her he will tell Dean what he has been doing, when the time is right.
'Seriously! Your working with her?' John commented.
'I know. It was a really bad idea.' San replies.
Meanwhile, Dean and Bobby perform a summoning ritual and a man appears. He is unharmed when Bobby and Dean shoot him with rock salt and when Dean stabs him with Ruby's knife.
'Why was your first instinct to attack me? I hadn't done anything to you.' Cas questioned.
'I guess that's just how we did it back then.' Dean replied.
The man renders Bobby unconscious, and reveals to Dean that he is Castiel, an angel. He tells Dean that he saved him from Hell on God's command, and that God has work for Dean to do.
