With the brothers out on a mission, Castiel was left in your care, mainly to help with researching how to stop Lucifer. Predictably, it wasn't easy to find any leads, especially with his banishment from Heaven and God being M.I.A.

On the bright side, you were nice company. Castiel considered you an ally, maybe even a friend. It helped that you decided to take the liberty to introduce him to some human experiences, teaching him all about what makes humans, well, human. It satiated his never-ending curiosity.

While conversing, one topic led to another, and you both ended up deciding to have a sleepover so Castiel could experience what that felt like. You even got him some pajamas, how sweet. The angel appreciated the gesture, even if he didn't see the point of it. Clothes were clothes. What was the use of needing so many?

Still, it was very, very comfortable.

"Nail... polish. It does live up to its name." He mused out loud, watching as the brush slid gracefully over his fingernails, coating them a colour that matched the teddy bear print on his pajamas.

Castiel brought his fingers up to his lips, blowing on the paint to help the process of drying. "It has an interesting scent."
