Castiel drew his lips to a line and rolled his eyes. “Your maturity level is admirable for someone who’s about to become an uncle.”
“ My maturity level?” Dean huffed back. “I’m sorry, I’m just here to support my friend - you’re the one who’s been giving me the stink eye since I got here!”
“Dean-” Charlie called, her voice low and calm.
“I've not given you any kind of ‘stink-eye’ Mr. Winchester - all of my attention has been on my patient.” Castiel stood, carefully placing the bottle of lube back on the little table. His shoulders locked tight, he raised an eyebrow. “I'm sure it hasn't escaped your notice that not everything is about you, and least of all this.”
“Hey, guys - I think…” Charlie started.
The nerve of this freaking guy! It's like every time Dean tries to be the bigger person, he's instantly shot down. Cas isn't giving him a freaking inch. Dean closed his eyes and took and deep breath before opening them and narrowing in on that stupid perfect face. “Dammit, I'm not trying to make this about me, I just want to help Charlie-”

And looking like she could run a marathon if it was to save either one of them.
Something inside of him broke, and he felt a few stray tears fall down his cheeks. In that quiet moment, just the three of them, in the dead of night, he realized how much he’d grown. This was the first decision he’d ever truly been proud of himself for making.
