"John Winchester you have some explaining to do."

Mary stood in the dining room with her arms crossed. John was standing in the doorway, one hand in his pocket, the other scratching the back of his neck.

"What do you want to know?" he asked.

"Is it true? You have another son?"

"I do."

"You have a girlfriend?"

"She's not my girlfriend."

"But you had sex with her."

"It was a one-night stand! Almost 4 years ago, during our separation."

"Oh well since we were separated I guess that makes it okay."

"Mary-"

"Do the boys know?"

"No."

"How long have you known?"

"She told me she was pregnant and she wanted to keep it. She knew about us and she didn't want to risk ruining what we have so she asked for very little. I send whatever money I have lying around for child support."

"John, you're on the kid's freaking emergency contact list at preschool!"

"I didn't know Kate gave them my number."

"Her name's Kate?"

"Mary this is ridiculous-"

"No, what's ridiculous is the fact that I haven't kicked you out of my house yet."

Nine-year-old Sam sat at the top of the stairs and listened in. When he heard his mom say that, he ran back up the stairs and down the hall.

"Dean!" Sam said, throwing open his brother's bedroom door. Fourteen-year-old Dean was lying on his bed with his headphones on. Sam shook his brother's arm until Dean opened his eyes and took his headphones off.

"What?" he asked annoyed.

"I think Dad's gonna leave."

"He's not gonna leave Sammy," Dean sighed. "They're just fighting again."

"But Dean it's serious this time!"

"I don't want to hear it, Sam," Dean said, walking out of the bedroom. Sam, of course, followed.

"But Dean-"

"Shut up Sam," he mumbled.

"Dean?"

"I said shut up Sam and leave me alone!" Dean said, going into the bathroom and slamming the door in Sam's face.

Sam stood out in the hallway and stared at the door. His lip quivered and a single tear ran down his face, which he quickly wiped away. He returned back to his place at the top of the stairs and continued listening in. His parents had been fighting a lot lately. Actually, Sam's never known of a time when something didn't go down between those two. Even on birthdays and holidays, there was still something to fight over.

Dean sat on the bathroom floor, knees to his chest. He felt bad for snapping at Sam but the damn kid wouldn't leave him alone. Every night this week, he had run into Dean's room telling him what was going on. Except, Dean didn't want to know what was going on, which is why he wore the headphones. But Sam still knew how to get Dean's attention.

When Dean had calmed down enough, he stood up and splashed some water on his face, exited the bathroom, and went back to his room.

"How long did you think you were going to keep this a secret?" Mary asked. The argument had dialed down and now moved to the bedroom, where John was packing a bag.

"I don't know."

"What? Did it just never occur to you that someday the kid-"

"Adam. His name's Adam," John said as calmly as possible.

"Okay, well what if Adam suddenly showed up on our steps as a teenager one day wanting his dad around for something?"

"Mary-"

"What if something happened to this Kate woman and you suddenly got custody of Adam? Would you tell us then?"

"Mary-"

"What if word got out around town? Huh? What if Dean or Sam heard about it at school somehow?"

John suddenly stopped packing.

"I don't think I should go Mary."

"Oh?"

"No! Clearly we still have a lot to talk about with this!"

"We can talk later. Right now I can't even see your face."

With that, John zipped up his suitcase and started walking down the stairs towards the front door.

"The boys are asleep. You can call them tomorrow," Mary said bluntly.

"They're not asleep!" John scoffed. "Bet you anything they've been listening to this whole freaking conversation!"

"Have fun at Kate's," Mary whispered. John left the house and Mary slowly closed the door behind him. She locked it, turned all the lights off downstairs, and made her way upstairs. She first went to Sam's room, who still slept with his door open, but all the lights off.

"Knock, knock," she said. She saw a shadow of a kid in bed. "Come on, I know you're still awake."

She heard a rusting sound of blankets and suddenly Sam had his arms wrapped around her waist. Mary bent down to hug him back and Sam cried into her shoulder.

"It's going to be okay. We're all going to be okay." She whispered in his ear.

"I don't believe it," Dean said from the other end of the hallway. "He actually left?"

"Dean." Mary said, standing back up and walking towards her other son. Sam followed her, still hugging her waist.

"You actually kicked him out?" Dean continued.

"Your father made the decision to leave," Mary corrected.

"You still didn't stop him!"

"I think a night off is what we all need. He'll be back soon."

"I'm going with him," Dean said, going back into his room. He got down an overnight bag from his closet.

"He's already gone, Dean."

"Then I'll call him and he'll turn back around and come get me."

Mary reached out for her son.

"Dean-"

"No!" Dean said, pushing her arms away. "I hate you! I hate him! I hate everything that's going on around here!"

Dean sat backward on his bed and put his head in his hands. He was pissed.

"I'm sorry you feel that way," Mary said, unhurt by Dean's words. She knew he didn't mean it. She turned around and left his room, closing the door behind her. She was surprised that after all that, Sam was still standing there teary-eyed. She put a hand on his back and guided him back to his room. There, she tucked him in and sang to him until he cried himself to sleep.

Afterward, she went back to Dean, who was back in bed with his headphones on. He was lying on his side, facing the wall. Mary climbed in next to him and removed one of the headphones.

"I know you're scared," she whispered in his ear. "It's okay to be scared, Dean."

"I'm sorry," Dean said.

"Apology accepted."

Neither of them said anything else. Dean stared at the wall as Mary ran her fingers through his hair. She waited till she knew he was asleep, gently removed the headphones, and tucked him in as well.

After, she turned the rest of the house lights off, made sure everything was locked and retired to her room for the night. There she took a long shower and also went to sleep.
