"Right now they're still working on their own sides," Crowley says. "Heaven following us, Hastur attacking us. They're not working together yet, and they might not. Even hating us as much as they do might be too much for them to stomach working together."

Then again, it might not. He remembers seeing the demon walk up with Hellfire for Aziraphale's execution. They seemed so pleased to be working together for that brief moment. He cant imagine what it was like in Hell with all that Holy Water. And they thought it was perfectly normal to behave that way.

"Humans are God's favorites, aren't they?" Crowley adds. "She made them. She wouldn't want them fought for something that isn't one of her Plans."
