Six days. That's how many days Sam has been gone.
Eileen had gone on a hunt and come back without hearing anything from him. That's when she called Dean. And Dean is freaking out. He already lost Cas. He can't lose Sam. He just can't.
Dean drove the seventeen hour drive from Arizona to Kansas in one go. He was exhausted by the time he and Jack got back, but his fear for Sam kept him awake.
They pulled out all the tricks. They tracked Sam's GPS on his phone. Nothing. It's like Sam's phone just doesn't exist. They looked for his car, but years of avoiding the law had made it impossible to locate him. It's as if Sam doesn't want to be found.
Dean's pacing around the map table when Jack comes into the room.
"Have you heard anything?" Jack asks.
"Have you done your homework?" Dean retorts. His response is snappy and completely fueled by anxiety.
"I can't! I'm worried about Sam!"
Dean stops pacing and runs a hand over his face. "Jack," he tries. Being patient with a kid is so hard. "We talked about this. You need to stay in school. Sam's going to be fine. He's been missing for longer and been fine."
Jack bites his lip. "But what if—"
"Stop."
The door opens, and Eileen walks in carrying takeout.
"Thank God," Dean says.
"There is no God anymore," Jack reminds him.
The three of them eat in silence. Dean's about halfway through his fries when he hears a car drive into the garage. The engine stops.
Dean looks at Jack. Jack is staring back. He heard it too.
"What?" Eileen asks.
"Someone just parked in the garage," Dean says.
The door opens. And Sam steps inside.
Dean stands up quickly, his chair scraping loudly against the ground. "Where the hell—"
Cas appears behind Sam.
