There's an entire play's worth of emotion that flits across Aziraphale's face when Crowley comments on God's lack of forgiveness. Oh, what a foolish little angel he's been, prattling on about his own worries when Crowley's already been through the worst of it. "Yes, of course," he replies quickly. He doesn't just mean humanity's side, although he'll help them as best he can, but sticking by Crowley's side, no matter God's or anyone else's opinion of him.

Thank goodness Thor says something to distract Aziraphale. Or rather, that shoulder pat that more or less meets its mark. It jostles him a little back to the present. "Hmm? Oh... all right, Thor." He gives the deity a smile. "It was good to see you again. Thank you for recommending the mead."
