As much as he knew the words Zira was saying were true, he couldn't stop the irrational resentment of them, wings stretching themselves behind Crowley in a gesture of Anger, as much agression as he still had the will to set towards his love. Alexia had been right, he realized- the love he felt, the fear over losing it, that was his, not a construct of this place. His motives were more selfish, possessive than he had originally believed, but the knowledge that he still had the gall to call Zira his, was a comfort in its own way.
All at once, he composed himself, wings wilting in an anticlimactic sort of gesture as his face turned ever so slightly into the touch. "I stood up to Ashmedai earlier today, to ensure you had the right to choose. I don't know what he's told you of the plan, but he wishes power over the Earth, and for me to advise him in such. Had you stayed Above, even as much as you were, you could have been used against me. But he will not harm his own, unless you give him just cause. You were smart in this, Aziraphale,"
His voice was rational, dry, his demonic side wholly unused to processing emotions. He wasn't sure if he meant that to guilt his lover or to praise him, but either way it was the truth. The one thing he could recognize, was an overwhelming amount of passion between them, and he leaned forward to burn some of it off in another kiss, just to clear the air.
