Either get rid of Castiel completely, or make Destiel canon. Bluntly, those are your two options. But please, enough of this ridiculous roller-coaster of “Dean and I do share a more profound bond,” and “I love need you,” to the two of them barely speaking to each other once every ten episodes. It doesn’t make sense, it’s profoundly bad writing and the opportunism behind it is so aggravatingly transparent, it’s cringe-worthy.

No matter which choice you ultimately make, you are GOING to make some faction of your audience mad. Sorry if I have to be the bearer of bad news for you on that front, but it’s past time y’all face facts. You have written yourselves into a dilemma for which there is absolutely no win-win solution. The only reason Captain Kirk never believed in no-win scenarios is because he was never part of the Supernatural fandom. You are not Burger King and not everyone can have it their way. So please stop writing the show like you are just desperate not to piss anyone off too much. There’s no getting around it at this point. Some significant faction of your viewership is going to wind up pissed at you when this is all over and done with.

You are damned if you do and damned if you don’t. You need to embrace that fact and get it over with, because right now you are just spinning your wheels, putting off an inevitability that you cannot circumvent.
