There used to be an angel in a trench coat

His name was Castiel Novak

He was in his words "AN ANGEL OF THE LORD"

He's the reason I will "ALWAYS KEEP FIGHTING"

He's played by the actor Misha Collins

Who besides Misha saved my life

Because of that I'll be forever grateful that I found Supernatural

That angel in a trench coat is also an angel with a shotgun filed with salt

That is who CASTIEL NOVAK is
