Wow! Beautifully constucted emotional journey, leading to the final: "And it makes everything he's ever done, and everything he might not get to do, worth it."

"Happy birthday, jerk," Sam says softly. So softly Dean barely hears him. He's just about to tell Sam to go to bed, dammit, when there's the briefest warm wet pressure on his forehead, Sam brushing a kiss there."
All this indicates of their consideration and closeness, each man's love for his brother, and all that family wins and costs, made me tear up! *blush*

Thank you.
