Castiel had just been informed by the Winchester’s that you were at the hospital after a rough case.

Castiel was an angel, you were a human.

Angels weren’t supposed to have feelings for humans.

Every time you had gotten hurt or killed.. it made him feel a certain way.

Castiel teleported into your room with a frown.

He sat by your side and took your hand, his eyes narrowing.

Castiel had never been taught to deal with emotions, it was hard seeing you hurt.
