"Last night on Earth," Dean had said jokingly to Jo in the kitchen, trying to get her to sleep with him. He'd been completely indifferent to the gravity of his statement, but the words weighed on Sam's mind as he sat moodily on the couch.
The beer on his knee was dripping its condensation through his jeans; he stared through its amber glass as though it would make this hell any better.
There was laughter floating through the house, the clinking of glasses and the smell of alcohol weaving hazily around him. Sam glanced around, seeing Dean at the fridge, Ellen and Jo at the table, wonderingly laughing as Cas threw back shot after shot, completely unaffected. On his other side, Bobby was poring over dusty old texts, trying to determine if they were going to die painfully, or if it was more likely to be quick. Confined to a wheelchair, Bobby wasn't coming with them in the morning – Sam had rarely seen him so livid.
Now, though, he was devoting his evening to trying to save their asses. It must suck, Sam thought, to be Bobby. Hardly more than it sucks to be us, but…
He stood. There was a blotch of water left from his bottle on his leg; Sam took a final swig and tossed his now-empty bottle in the trash. "Hey," he said to Dean, his voice coming out a lot more quietly than he was expecting.
"Hey, Sammy," Dean replied, standing by the table and watching Cas drink. There was a smile on Dean's face that Sam hadn't seen for a long time. He couldn't bring himself to stop Dean from calling him "Sammy" anymore. It didn't matter. Not anymore.
He didn't speak. The girls were laughing, Cas' confused expression bringing a smile to Sam's face, too. He took another beer from the fridge, and looked around at his family. They weren't blood, except for he and Dean, but he'd never known this depth with any other people.
Bobby called them all over in front of an old camera. As he walked over, his brother slightly in front of him, this fleeting moment twisted something in him. Last night on Earth, Sam thought, putting his arms around Cas and Dean, Ellen right in front of him.
It wasn't so bad, he decided. If it was his last night on Earth, Sam Winchester was glad that it was a damn good one.
