growing up Dean never believed in God much less an angel, his world was turned upside down when Castiel a freaking angel of the lord ‘gripped him tight & raised him from perdition’
a few months passed, Castiel or ‘Cas’ as Dean now calls him, becomes pretty important to the brothers. everyone in Heaven has took notice of this & often times complained that Castiels loyalties lie elsewhere. you being Gods favorite angel, it wasn’t a shock to anyone when you decided to travel to earth & confront Castiel
as you appear in the bunker, Castiel looks at you in shock. he sighs as he says
“Hello Y/n”
out of the corner of your eye, you can sense a pair of devilish green eyes staring right into you, a voice speaks up
“Cas who’s your friend”
he asks with a smirk on his face
