Can I just say that there’s something weirdly satisfying about seeing “Aziraphale” act like Crowley?
Like, when Crowley’s pretending to be Aziraphale, “Aziraphale” is quiet, stoic, his voice is deeper, the accent isn’t as posh. In that last scene before they switch back, “Aziraphale’s” voice is a relaxed, low growl effectively indistinguishable from Tennant/Crowley’s own and he’s slouched and sprawled and it’s so weirdly satisfying.
Aziraphale’s better at playing Crowley; he matches the audacious sarcasm very well, probably because it’s a level of freedom he’s always kind of-sort of wanted to experience himself. But Crowley’s barely under the surface of “Aziraphale”. It’s basically Gabriel and the other angels’ own arrogance and complete lack of knowledge or interest in Aziraphale that made them fail to notice how obviously different he was.
Crowley!Aziraphale was actually really awesome to see and I loved it and rewatch that part over and over, especially the scene right before they switch back when he’s slouched over the bench.
