It's a rainy day and Dean is overwhelmed with emotions and pent up feelings, so he decides to drive for a while. Sam understands that he needs some time to be alone and says nothing, just stays at the motel, doing some research.
Dean drives off in the Impala towards the woods, and when he gets near, suddenly he notices a body lying on the roadside. It's a man. An unconscious man lying on his stomach. All bloody and dirty.
The Impala stops, leaving a burned rubber trace on the concrete, as Dean slams on the breaks. He rushes out of the car and kneels beside the body.
"Cas?" His voice cracks as he turns the man over and sees the painfully familiar face covered with a beard.
"Dean…" The angel says weakly and barely manages to open his eyes to look at his charge. But it's still enough for the hunter to feel the shivers down his spine.
"Don't talk. Let's save it for later. I've got you, Cas. And I'm not losing you again," Dean murmurs and picks the angel up.
Castiel feels as light as a feather in his arms as Dean walks towards the Impala with the angel pressing his head to the hunter's chest.
"You're safe. It's my turn to protect you." Dean places a kiss on Castiel's forehead before putting him in the Impala. "We'll be fine. Nothing's gonna get to us, I promise."
And Dean knows it's true.
The End
