What does Nina do when Shax starts dragging Maggie through the mud?
Nina: "She's not embarrassing herself, she's- she's braver than anyone I know."
She stands up for her. She tries to protect her, refuses to let someone talk about Maggie like that. She doesn't just stand there and watch, she does whatever she can to defend her, even though she's a regular human being and these creatures threatening her, Maggie, and Mr. Fell are very clearly not.
And what does Crowley do when God starts dragging Aziraphale through the mud?
What. The. Hell. Is. That.
He just... shifts his gaze from God to Aziraphale with this cold... expectation and... indifference? This dark, detached look? Aziraphale is obviously hurt by what's being said, and Crowley just... stands there, leaning against that damned bookshop pillar, looking at him as if he deserves to hear it. Like, "Well? What do you have to say to that?"
It just gets under my skin. It's unbearable. It's revolting.
Crowley would NOT stand by while someone said things like that about his angel right in front of him.
This is NOT the Crowley who, when he thought Aziraphale had died for good, lost every shred of hope and every desire to save the world, and instead went off to get drunk because, without Aziraphale, he saw no point in enjoying Earth or any of its little pleasures.
Aziraphale is the most important person in his life. The person closest to him. Crowley has risked his own life for him over and over again. He is his first, only, and best friend. His light, his hope, his love.
Just being around Aziraphale always lifts his spirits, even when he's irritated or upset.
Aziraphale means the world to him.
And when Crowley played Aziraphale at the end of Season 1, he portrayed him exactly the way he sees him: brave, courageous, smiling even in the face of danger and death, compassionate, forgiving, and full of faith.
Crowley sees the best parts of Aziraphale: his courage, his resilience, his unwavering commitment to his principles even when it threatens his own existence or well-being; his faith in something better; his ability to find light in the deepest darkness; his ability to smile at people who, for centuries, have treated him terribly.
And the fact that Crowley reacts to God's words about his angel with such coldness and indifference...
I don't know who you are, or why the hell you look like our Crowley.
And let's not forget that throughout most of Season 2 he relentlessly bullied Gabriel and practically drove him toward a window just because Gabriel once told his only friend to shut up and die.
