Crowley referring to Gabriel, Michael, and the others not as "angels" but as (the honestly more accurate) "angelic entities" in front of Aziraphale is such a wonderful bit of flirt.
Crowley very deliberately not using "angel" to describe anybody else as a nod to Aziraphale that Crowley's romantic pet name for him is a word that he sees as belonging just to Aziraphale is really sweet.
Romancing his angel and shading angelic entities have always been the twin passions of Bildad the Shuhite.
