The thing about Destiel is that although they have so many beautiful, purposefully written moments, some of the most profound things about them are just pure accident. Dean calls Castiel âCasâ not knowing that the suffix âielâ literally means âof God.â He calls him Cas because he wants to give him a nickname and he unknowingly removes Godâs ownership from him. Just imagine that. When your very name binds you in obedience to an absent father. You follow orders and youâre a good little soldier because what other choice do you have? You are of God and the sum of your millennia long existence is to do His work, to be His minion. You rescue a soul from Hell because youâre commanded to and then you watch over him even though he has no respect for divine order and always asks too much of you. And somewhere along the way he calls you Cas because he thinks Castiel is a mouthful and you know you should be irritated but you canât be because Cas has no binding, no ownership. Dean calls you Cas and it almost feels like heâs tempting you, offering you a life when youâre not of God but of yourself. So you Fall for him and maybe you fall for him, and one day youâre working a case with him and Sam and one of them says âCasâ and you realize that you were wrong. Cas is just as binding as Castiel. It bound you to them.
