Hmm. Since technically Aziraphale has been not himself, literally, for the better part of the month...

1. Studying - He's a bit mopey about his Crowley-summoning not working. I know that's not an action, per se, but between himself and Crowley, there was a lot of extra note-taking and studying about what exactly went wrong. He hasn't given up, sadly.

2. Familiar Bond - After the failed summons, he'll finally start trying to bond more with Creme Brulee instead of just treating it as a sort of pet.
