I think it'd be easy to handwave that Aziraphale did something - that was pretty much the original plan, that he'd interrupt Sunshine and Spike making out and she'd direct him to the resident angel. So we could say they worked something out there. Though ultimately he'd probably do better with Daine, if he could just get over the whole 'you tore my home and livelihood to pieces' thing.

Peter could be rude to Greta. Lilly could bite him.
