The angel named Aziraphale quite liked Eden. It was a beautiful place, full of newly created life and very different from the constant whiteness of Heaven. Not that Heaven wasn't Nice, of course it was, it was Heaven. But, well... Earth was nice, too, especially the sunrise to the East. The blond raised his hands over his head, appreciating the warmth brushing across skin with a small hum. The sun was a nice thing in general. "I know I've no right to pass judgment, Father," he murmured under his breath, closing his eyes and smiling slightly. "But I think it's all absolutely beautiful."
"Nah," came a casual voice from above his head. "It'sss too cold when the sssun sssets. Ssssomeone sshould take care of that."
Making a sound very close to a startled squeak, Aziraphale took a very quick step back to turn and look up. It took less time for the sword he'd been given to catch fire and point at the speaker's head, which turned out to be in the vaguely wedge-ish shape of a large snake. The blond lowered it when this registered, placing the weapon on the ground when it stopped flaming. "Hello," he greeted instead. "Ah... Sorry about that."
If snakes had eyebrows, one of this one's would have been raised. "Jussst pointing that out... No need to get ssso excssited, Angel."
"You startled me," the angel said rather reproachfully. "I did apologize," he added, looking rather embarrassed. "And my name is Aziraphale. What's your name?"
Even with limited mobility of facial features, the snake managed a decent shot at 'embarrassed'. "I, ah... Don't really have one. At the moment. That'll change sssssoon, though, I exsssspect, oncsssse I-"
"Oh, my dear!" the angel interrupted, looking mildly horrified on the snake's behalf. "I'm so sorry, I shouldn't have asked... I can give you a name!"
The snake's jaw dropped. "...'hat?" The horrified question didn't sound quite right, as he'd unhinged his jaw for extra dramatic effect.
"I can! I can at least try, and it shouldn't be too difficult." He fell silent, looking at the snake for a long moment. The snake was looking as if he might be sick, or try to run the other way. Well, more like slither given the absence of limbs. Maybe a wriggle, or crawl-
The angel brightened abruptly. The snake looked mildly horrified. "Crawly!"
The newly dubbed Crawly hissed something obscene, his worst expectations exceeded.
It was an inauspicious beginning to an eternal friendship.
So... After wondering for at least a week how on EARTH the two of them met in the first place, this happened. Aziraphale doesn't have quite the right knack for naming things. Oh, and the title? Copy-pasted from the King James Version of the Bible. (Well, the ELECTRONIC KJV...)
And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.
Just a little snapshot of their relationship.
