I love the fact that Cas fell in love with Dean.
Now you might be thinking, “Well duh.”
But hear me out!
What fell in love with Dean wasn’t an Angel who looks like a man, No. That’s just Cas puppeteering a dead man’s body so he can walk on earth. (Which is a whole other issue and a topic for another day.)
What fell for Dean (a mortal human) is a GIANT, thousand eyed, golden ringed, ancient, flame covered, multi winged, Chrysler building sized (1,048 feet (319.5 meters)), probably multi headed, look at it your eyes will burn out, Angel of the Lord.
That is my new favorite SPN thing. (I have been looking at drawings of Cas' true form ALL DAY and I can't get enough! *Cries*)
