Dean and Jack had to get a message to Prue. The boys had discussed their situation and come up with only one way of getting out of their predicament. As it was, with two dead, one incapacitated and two in a demonic prison cell there was no way of making things right. As ridiculous as it sounded to them both re-winding time was the only way. They just hoped that Prue was capable of it.
"Dean, we're ghosts we can do anything"
"I know that, so once again..." Said a confused Dean
"We tell Prue to turn the time back to before Leo and Sam got shot. Then we tell our past selves not to drive to the hospital" Replied Jack
"Right. So how do we do that again?"
"Did you listen to one word said Dean?" Asked an exasperated Jack.
Dean eye-balled him and Jack thought it a good idea to answer him.
"That's where you come in. You got to possess Dad" He looked at him guiltily
"Jack, you can't be serious, I am not possessing Dad"
"You have got to, for one he doesn't know I'm dead and he's the only one apart from Prue available to possess"
"Don't expect me to be happy about this. I hate it when you're right" Complained Dean
Jack smiled like a cat who had got the cream, he could wind his big brother round his little finger.
The two brothers went into the house. John was in the Halliwell's house trying to come to terms with his son's death still cradling his limp form in his arms.
Jack looked on. John gasped and Dean gained control of his Dad's body, it felt heavy to have a body again.
"Sorry Dad. I got to do this" he said internally, he hoped his father would understand.
Prue was tending to the Leo's injury when John's gasp got her attention.
"John?" Said Prue "What's wrong
Dean spoke and found it extremely odd to have his father's voice come out instead of his own., but carried on.
"No it's me, Prue. It's Dean"
"How? What?" Said Prue "This is too much"
"Don't even go there, Jack convinced me it was the only thing to do"
"Wait, Jack is dead too?"
"Afraid so, now listen to me, you have got to turn time back, please tell me you can do it?" Said Dean
"Yeah, we did it before, I know what to do" She said professionally
With that Dean left his father's body and he and Jack prepared themselves to confront their past selves.
Prue did what was necessary, and the time returned to when Jack and Piper were in the attic. The spirit forms of Dean and Jack stood silently, unseen in the corner of the room.
They waited until Piper froze the whole place, then Dean picked up a pen with his transparent hand and tossed it across the room, it hit the wall and fell to the floor.
"Where the hell did that come from?" asked Piper looking at living Jack.
"Dean, how the hell did you pick that pen up" Asked spirit Jack, shocked
Dean laughed at him.
"I guess I'm not as dumb as you think little brother?" He said smiled.
"I'm impressed; I guess you're not a complete dim wit then!" Replied Jack
"Like I always say to Sam, you don't have to be college graduates to be a genius" he said "Am I going to be the one to scare the hell out of them or are you going to do it?"
"You do it!"
Dean's form became solid.
"Jack" he said
Jack wheeled around and looked alarmed at his brother.
"Dean, where did you come from?"
"Listen to me Jack this is important, I die in the next few hours, I get hit by a weapon tipped with poison, and I know I'm Mr. Sunshine but you die too. I'm here to change that."
"Dean, tell me what happens, I can change it"
"You'd better had. Now, Leo gets shot by a dark lighter, an arrow also hits Sam in the arm. You and Sam drive to the hospital and the demon crashes the car. Sam is injured but he lives, but you get snatched straight from the site and taken to a jail. You die from your injuries in Phoebe's arms.
Jack was completely speechless. Piper who was more used to ghosts from the past appearing before her had a calmer manner.
"Jack go and get a glass of water, calm down" Piper instructed
"Dean, I haven't met you yet, but I have met Jack, so I trust you. We will kill this demon. We will save you" she said determinedly.
"Save us all, Piper" Said Dean smiled at her and disappeared.
Events played out just as they had been informed, but they had been given the gift of hindsight and it gave them an amazing amount of confidence and faith that they would put an end to the evil entity responsible. Piper sat with Leo after he was shot and Prue helped Dean bandage Sam's arm and take out the arrow.
"So, Phoebe's gone, who's next? Asked Piper
Sam clutched his head as a painful headache came.
"Sammy, what is it?" asked Dean
"It's in a building downtown, the demon; Phoebe's able to send me a premonition"
"You've got the same connection as me and Jack, this connection seems to amplify our powers somehow"
"Do you know the building she was in?" asked Jack
As they left the house to go to kill the demon Prue and Dean were last to leave the house.
"Dean, legend goes that the oldest sister possesses the strongest power" Said Prue "Oldest brother in your case" She added with a smile.
"I know, I felt your power through Sam's vision!"
"You broke my teeth and my nose in one punch" She replied
They looked at each other and smiled.
"You worked it out" Said the voice of Prue's mum, Patty Halliwell.
Patty stood before them with a serene smile on her face.
"What?" asked Dean and Prue in unison.
"Piper and Jack and Sam and Phoebe's powers combined have al given you the information that has lead you to this point, yours combined and this demon doesn't stand a chance"
"Thanks mom" said Prue
They left the house and followed Sam's directions to the office tower block and walked into the crisp, clean lobby. Passing the reception desk, all with a stony determined glare, Piper and Jack, Sam in the middle and Prue and Dean in the front they went to make war with the demon.
