Dean came running in from the kitchen to the library. There he saw Sam fall to the floor in a dead faint and lay there in a spread eagle like fashion. He heard a voice in a demanding tone attempting to get the attention of Sam from the phone that lays a few feet away from him.

Picking up the phone and lifting it up toward his ear, Dean could hear the person asking for Sam. Dean could tell from the tone of voice that it belonged to his long since dead father. Knowing that his dad was dead but still talking and alive right now meant something big is about to start brewing and it could possibly be about the darkness as well.

Taking a big breath and then he exhaled Dean started talking.
He said, "Dad, how are you alive? Do you know why you are here? What happened?"
While Dean was asking all this, he also checked up on Sam as well. Just to make sure he hadn't hurt himself too badly. He sat on the ground, putting Sam's head on his lap and started stroking his hair, waiting for him to wake up and join the conversation. He sat waiting to hear what his father had to say about all this and why he was alive to begin with.

John who had just picked up the phone and started to dial one of Sam's cell phone numbers, that was hopefully still active, the phone started ringing. It rang for a few minutes until it was picked up on the other line by none other than Sam, his younger son. After hearing John's voice there was a large crash.
"SAM! SAM!"
He squeezed the life out of the phone with his hand, his knuckles turning white. Until he finally relaxed when he heard another voice nearby. John was hoping it was Dean, but wasn't sure so he continued calling out to Sam in case he could still hear. After some time he heard the phone being picked up and thought it was Sam. so he still continued to talk. Then all of a sudden he heard Dean's voice and his questions that just fired out of his mouth.

Taking another breath John took a few minutes to decide on what to say for the questions.
Thinking real hard he replied with, "I'm not sure how I am alive just remember being dead and the next I know I'm on a forest floor with no memory on how I got there. Also, no for the other two questions on how I am here and what happened at all. Now where the hell are you Dean?"

Dean was paying attention to what his dad was saying while thinking of calling Cas after he gets off the phone with his father. Figuring out that his dad doesn't know after hearing the replies to his questions. Figuring that they had to meet up someplace decided that it would be at the bunker since it was demon proof and with other supernatural monsters.

Dean told his dad, "Hey dad lets meet up at these coordinates and I hope to see you tomorrow sometime."
John replied, "Sure," and started writing down the coordinates that he got on a paper and pen from the receptionist. Telling Dean that he will see them tomorrow sometime then hung up the phone.

John thanked the receptionist on the way out towards his room where he would take a shower, wash his clothes, and sleep until tomorrow to meet up with his sons for the first time in a long time.

Dean closed the phone after talking to his father. It was then that Sam decided to wake up. Punching the numbers for Castiel on the phone waited until Cas picked up the phone.

"Hello Dean," Cas said.
Dean went straight to the point, "John is alive. He called me. What the hell is going on?"
"I do not know Dean. I will be back late tonight."
"Thanks."
Dean hung up the phone and turned his attention to Sam.
