It was better than a punch to the face, but Dean's kiss still managed to knock the wind out of Sam, or suck the air out of him, one or the other. He kissed Dean back until his lungs started to protest the lack of air and he gave his brother a firm shove to get him to pull back.
"Yeah well, look how great saving you from Hell went. We failed. In fact, we let Lilith walk right in and release the dogs. We couldn't have made it easier for her if we rolled out the red carpet." Sam wriggled to sit up a little.
"Dean, I'm not saying I'm going to lie down and let it kill me, but we have to be realistic, me dying is pretty likely. I mean, we're all alone in this. Cas is so far off the reservation he's practically a stranger, Meg is dead, Kevin is working so hard with the tablets his brain is likely to explode, and we got Crowley breathing down our necks. We don't know what the next two trials are going to be. But we gotta look at this realistically and face the fact I'm probably not walking away from this."
He knew Dean didn't want to talk about it. He knew it hurt Dean to even think about it. But they had to face facts. They couldn't just bury their heads in the sand.
"You heard what Cas said. And that's after one trial."
