Cas randomly starts to cry because he’s not used to the weight of full human emotions and Dean wraps his arms around Cas, hugging him tight, comforting
"Shh, it’s okay Cas. I know. I’ve got you. It’s okay, angel." which only makes Cas cry harder
"But I’m not an angel anymore, Dean!" he sobs
Dean kisses his forehead and just squeezes him tighter, "You’ll always be my angel."
