[Funny thing - Crowley has always quite liked Aziraphale, whether he admits it or not (or not) and this morning when he woke up, all he wanted to do was see what it was like to live like his roommate for a while. Call it a lark.
And when you're a demon with full control over your appearance? Well, let's just say that Crowley's plants are terribly confused.
The problem is, for all his many years of hanging out with Aziraphale and observing him, he just doesn't have the knack for being him.] Good morning, dears. How are we feeling today. I feel the need to get a good thwart on and wear lots of tartan.
Next I think I'll open a bookstore and never sell anything.
Right, erm. I mean, I think I'll go feed the ducks.
[You can catch Crowleyphale out feeding ducks, bestowing random unneeded blessings, or drinking far too much tea (spiked) anywhere in the City or just ping him at home.]
