A/N: I don't know why, but I've recently became obsessed with what I call 'Supernatural secret siblings' fics. I love the family-ness of SPN so I've decided to try and write one :) I know Oz and Willow don't get together until season two, but I don't care :P set during season 1 of both SPN and BtVS.

FINDING OUT

John Winchester sat on the couch in his stingy motel room. He wiped his face with his calloused hand, as if trying to wipe away the anxiety and stress. If only it were that easy. He knew the consequences of his choice, and he wouldn't take it back, but now it was real. Two months to the day until the hellhounds came for him. He couldn't believe it'd already been nine years and ten months since he made the deal to save his son, Alexander Winchester, known to the world as Xander Harris.

**flashback**

John's phone rang, waking him from his very rare sleep. Without bothering to check caller ID, he pressed the answer button and held the phone to his ear.

"What?" he snapped gruffly.

"John? It's Jessica Harris." A female's voice sounded on the other end. John instantly woke.

"Jessica? What is it?" John asked. There was only one reason Jessica would be calling him – Alexander.

"It's Xander. He was in an – accident – last week." John didn't miss the way her voice faltered on the word 'accident'. "He's been put in a coma. He's in critical condition and the doctors don't know if he's going to make it. I just thought you should know." and with that, the line was dead.

John immediately got into his car and drove until he found a crossroads. He never thought he'd do this. Not once in his life did he expect to make a deal with the things he killed on a daily basis.

"Come on, come on." He muttered to himself as he waited for the demon. He heard gravel moving, so he spun around and found himself looking at an attractive demon in her twenties.

"John Winchester." She smiled devilishly. "What brings you to my side of the tracks?"

"I'm here to make a deal. My son is dying and I need to save him." John growled.

"One of the famous Winchester boys is dying!" the demon looked excited. "Which one is it? Daddy's soldier Dean or little Sammy boy?" she teased.

"It's – it's neither. My son Alexander, he's in a coma, he's only six."

"Oh, well that's boring." The demon deadpanned. "I guess I don't really have a choice though. So, you get ten years and your son lives, is that the deal?" John nodded. "Alrighty then, pucker up."

John grimaced when the demon grabbed his face in her hands and brought their lips together. By the time he opened his eyes, she was gone and he was standing alone at the crossroads.

**end flashback**

Sighing, John dialled Dean's number. It rang once, twice, three times. No answer. John was about to hang up when he heard his son's voice.

"Dad?" Dean sounded tired, worried and surprised.

"Hey son." John spoke after a moment's silence.

"Dad, where have you been? Sammy and I have been looking for you."

"I know, I've been around, keeping an eye on you. Listen Dean, there's something I need to talk to you boys about."

"What is it? You sound worried."

"I can't discuss it on the phone; how long until you can get to the Forest Motel in Minnesota?"

"We're only a few hours away. We'll meet you there." There was a pause and no one said anything. "Bye dad."

And then Dean hung up.


A few hours later, and Sam and Dean were sitting across from John at a coffee table in his motel room.

John cleared his throat awkwardly.

"Look, I know you boys have been looking for me and I'm sorry for going MIA, but I needed some time on my own." John took a deep breath before continuing. "While you were looking for me…I was looking for your brother, Alexander."

Dean's jaw dropped to the floor and Sam just looked confused.

"Wait, brother? What brother?" Dean asked.

"Sixteen years ago, I had a…fling, with a woman named Jessica. She got pregnant and left. I agreed to never make contact with them, because she was already married." Both boys looked shocked and betrayed, but John kept telling his story. "Nearly ten years ago, I got a call from Jessica telling me Alexander was in hospital in a coma. It was critical and there was little to no chance he was going to make it through." Every instinct in John's body was telling him to look away from the hurt in his son's eyes, but he had his pride, and his pride wouldn't break the eye contact. "I made a – a crossroads deal to save him. I had to. You know I'd do it if it were either one of you."

A long and eerie silence filled the room. No one dared to speak. Sam and Dean were still processing the information. They had a sixteen year old brother. They had to be even more responsible now than ever before.

"How long until your time is up?" Dean asked his voice croaky.

"Two months." John told him. "I'm going to Sunnydale to see him. I want to meet him before, I…before my time is up. He's my son, he's your brother and I want you two to meet him too."

Sam and Dean exchanged looks. It was as if they were having their own telepathic conversation. Dean finally looked at his dad to give him an answer.

"When do we leave?"
