"What about you? What happened after I left?"
Cas can see Dean tense up. He wonders how bad things could have been for Dean. "I was at school when it happened." Dean rolls onto his back and to stare at his ceiling. "The cops came in and pulled Sammy and I out of class. Our house burned down. Mom was inside. She didn't make it. Practically nothing made it." He rolls over and reaches into the night stand drawer.
He pulls out a picture and shows it to Cas. The picture is of a young, happy couple with two children. Cas recognizes Dean, he's the clearest. He kind of recognizes Sam and Mary, but the man is foreign to him. He shows it to Dean, "Who's he?" Dean looks rather sad, "That's my dad, John. He was gone a lot." Cas stares at it for a while longer before asking, "Where's Adam?"
"Adam's my half-brother. We didn't know about him yet." Cas wasn't expecting that.
Cas waits for him to continue silently. "After the fire, my Dad fell into alcoholism. We went to live with Bobby here. It was nice for a while, until Kate - Adam's mom - called us to the police station. She told us that my dad had an affair on my mom and the result was Adam. She, uh…she shot herself." Dean swallows, and Cas feels his stomach drop. "I stopped Sammy from seeing it, but I wasn't so lucky. Bobby took Adam in because he didn't have anyone else. He's a Winchester now, legally." Dean falls back against his pillows. "That was when I started seeing Missouri Mosley. She's my therapist." Dean seems ashamed at the word, like there's something wrong with him.
"I couldn't sleep at first, cause all I saw was her. Her… all over the walls. I was a bit insomniac for a bit. I got better as time passed, but…life seems to want to fuck with me. Junior year, my Dad and I were going to the bank when this truck driver fell asleep at the wheel. We got into a crash, and I broke my arm. We were okay; we got out of the car. He was calling 911 when this car swerves to avoid crashing. It was going to hit me, but my Dad pushed me out of the way. The car pinned him to a tree. He…uh…he bled to death. It took the paramedics nearly twenty minutes to get to us. He was dead by then. He died in my arms. That gave Missouri more material to work with."
"And then, of course, I caught Bobby and Crowley getting it on in our kitchen. That was horrifying. Spent three whole sessions on that alone." Cas realizes he's only half joking.
There's a long silence where neither look at each other, "You left the day my mom died."
Cas is stunned into silence. He doesn't know what to say, so he leans down and hugs Dean instead.
Dean stiffens, and Cas thinks he's done the wrong thing. He flushes, embarrassed at his own social ineptitude and goes to move away. He doesn't expect Dean to hug him back, but he does. Dean lays there with his face buried in Cas' neck and his arms wrapped around Cas' waist. When Dean doesn't let go, Cas' back starts to hurt from the way he's contorted, so he shifts and lays down next to Dean.
Cas doesn't know how long they stay like that, curled around each other, but after a while Dean dozes off. He still clings to Cas as if he's afraid he'll leave again. Soon after, Cas hears Adam get home with Garth, and they both head into Adam's room. Cas can hear them talking about homework, and Adam puts on his music. It's a bit different from Dean's taste, but all Winchesters like the same basis of music. He listens to Adam's music while he lays there, and eventually falls asleep wrapped up in Dean's arms.
