Aziraphale is positively adorable. Crowley lounges back as he lays there, watching the angel sit, all but cross-armed in the bed next to him. The very picture of someone who never rests, never relaxes. Crowley wouldn't want him to change, not for the whole universe.

He wants to watch him forever, but he can't. He can't even really keep his eyes open for very long. He leans into his pillow and his eyes slowly close. He lets himself sleep, eventually throwing an arm around the angel as he dreams.

It's not snuggling, because Crowley Does. Not. Snuggle. It's more like...leaning on aggressively while sleeping.
