There are tears in Sam's eyes as he looks around him. There are no candles on his cake this year, but he does have one - created by his mother no less. He gazes in wonder at all his family and friends: his mother, his father, even his grandparents, Jess, and every dog he's ever loved. There's Castiel, Bobby, Jo, Ellen, Ash, even Gandhi, all looking at him and smiling.
But it's to his brother he ultimately turns. "Wow, Dean! This is just . . . Wow!"
"It's your birthday!"
"We're dead, man. There are no more birthdays."
"Hey, my little brother's birthday is always going to be a special day! Now blow out your candles."
"Huh?"
Dean's grin widens as he places his candle in the center of the ones John, Ash, Bobby, and Cas have already put on the cake. It took some doing to get something with a flame not only in Heaven but in Winchesters' hands, but they did it. He'll always come through for Sammy - now. "Blow out your candles, Sammy. Make a wish."
"I'll blow 'em out, but I don't need to make a wish. I've got everything - everyone I could ever want right here." And he does.
The End
