Crowley chuckles, low and fond, and pulls Blake towards the bed.

"Who said you're allowed to leave?"

With a grin, he teases at the hint of another kiss before turning his attention to kissing Blake's jaw. He'd been missing more than just his memories in that time and there's a lot of lost affection to make up for.

There is no one else in the universe who would take care of him without his memories--no one who wouldn't do it simply to manipulate him at best. Blake is a good man, but that's not why Crowley cares about him. It's in his loyalty and his capacity to care for Crowley.
