Sick Partner
Crowley was a bad cook. A terrible atrocious cook. He could burn basically anything on the face of the earth, including but not limited to pasta, fried eggs, scrambled eggs, water (don't ask), toast and every kind of vegetable imaginable.
It wasn't that much of an inconvenience because Crowley didn't eat anyway. As a demon, his body didn't require food and he found eating to be more of an inconvenience than anything.
Aziraphale was quite the opposite. He adored food of all kinds and saw it as a way to be close to the humanity he adored so much.
Crowley was a little worried when Aziraphale asked for some soup. He couldn't quite bring himself to say no to the man - Aziraphale was sick after all - but he had precisely no idea how to make the damn stuff.
It took a long time and a lot of attempts but finally, Crowley set a bowl of something vaguely resembling soup in front of Aziraphale. "I did my best," he mumbled.
"I know dear. I sure it'll be delicious," said Aziraphale, picking up the spoon. "It's actually pretty good."
"Thank Satan. I was sure it would be terrible. Can I get you anything else?"
"Just some hot chocolate please."
Crowley went back to the kitchen and rattled around a few cupboards. "Where do you keep the stuff?"
"It's in the cupboard above the stove," called Aziraphale, before breaking into a coughing fit, reminding himself of how sick he was.
"I'm not sure I like the sound of that cough Angel," yelled Crowley. "You should go to the doctor."
"I'm not sure that's a brilliant idea. I'm an angel – our physiology is probably different from humans."
"Probably." Crowley passed Aziraphale his hot chocolate, which was even in his favourite mug. "It is weird that you're sick though. I didn't think angels could get sick."
"It turns out that we can if we've been on earth for too long. I asked upstairs about it yesterday."
"Huh. That's interesting. Can I get anything else for you?"
"No, I'm good. Just sit with me for a bit..."
And just like before, Crowley finds that he just can't say no to Aziraphale.
