"Your brother is lucky all he suffered was a mild concussion, I'd like him to stay here but he refusing. Just keep an eye on him" Instructed the doctor.
"You got it" replied Jack.
Sam, Jack and Dean walked out to the car.
"I want to know why I felt your vision. Try to keep it to yourself next time." Said Dean venomously
"Dean, it wasn't my fault, I've got no control over these damn visions" Said Sam defensively
"Hey, quit it, the two of you are really beginning to annoy me" Snapped Jack.
The three of them got into the car and drove away to the motel in silence.
In the morning Jack was up before his brothers, he decided to go and find the Halliwells. He wrote Sam and Dean a note and walked to the Halliwell's house, Dean would kill him if he took the car without permission, plus Sam and Dean needed some alone time.
"Can I help you?" Said Piper when she opened the door to Jack.
"I hope so, I'm looking for Prue Halliwell, I believe she met my brother, Dean, yesterday and he thinks she may be able to help us"
"Prue's at work at the moment, but I'm her sister I can help"
Piper was wary of Jack as she now considered him evil since the incident with Prue and Phoebe's premonition. Jack and Piper got to basics and went through things like powers and the power of three.
"So you're psychic, huh?" She said, still very suspicious.
"No, I'm not but my little brother Sam is" Said Jack, proudly.
"There's three of you?" she said, more interested.
"Yes, I'm in the middle, Sam's my little brother, Dean's my big brother. What piqued your interest?"
"No, reason" she said calmly "I want to show you the book of shadows I'll fill you in up there" They headed to the attic and stood by the book.
"So you think my brothers and I are...an equivalent power of three?" said Jack, disbelievingly.
"Yes, my sisters don't know yet, I haven't had a chance to tell them yet but I found a legend that said that an opposite power of three may exist"
Leo orbed in.
"Hi honey" She said, suddenly a picture fell off of the wall. Piper froze it, however the whole room froze instead of just the picture, she un-froze Jack and Leo.
"That was weird, I froze the whole room and I only meant to freeze the picture"
Leo looked out of the window.
"Er...Piper...you froze the whole street"
"What, you can't be serious...I'm not that powerful" She looked out of the window, and gasped.
"You!" She said, Jack looked alarmed at the way she addressed him,"Where was your hand?" She asked.
"On the book I think. Why?" He replied
"Where was yours Piper" Asked Leo.
"On the book, too" She answered.
"Looks like you were right about this guy" said Leo smiling at Jack.
Jack was now totally mind-blown, he had discovered so much information in the last half an hour it was making his head ache.
"Your the middle sibling, right?" Asked Piper in order to confirm her theory.
"Yes" Said Jack, increasingly confused.
"Me too, it explains why Sam and Phoebe had the vision at the same time and why Prue and Dean felt each other's strength, they are linked in the same way that you and I are" She said excitedly.
"Hang on a second, you're saying...I strengthen your power somehow because I am in the same position in the family as you?
"...Yes" she said "This is big"
