Prompt: Supernatural, Dean + Castiel, Dean tells Castiel he needs to pick a date for his birthday
Castiel considers carefully, pondering all the days he has existed. He was an angel for a large majority of his days; many of those days are important, in both his 'life' and Creation's history. He discards them all.
Then he thinks about the days and nights since he met Dean Winchester, since he was given the greatest task yet of his existence. All those days and all those nights, guiding Dean, guarding Dean, touching and being touched by Dean… changing and being changed by Dean.
Yes. Considering Dean, watching Dean laugh with Sam, a sound sorely missed, the choice is easy.
"My birthday," he says, catching their attention, smiling at Dean. "September 18, 2008."
Sam understands immediately, by the look on his face. And after Dean comprehends, his expression of wonder steals Castiel's still-new breath.
