âIn the first three seasons, Kripke had a staunch âno angel policy.â Supervising producer Sera Gamble posited the idea of angels back in season two, with her episode âHouses of the Holyâ, âbut the reason [the creature] didnât turn out to be an angel in that episode,â Kripke relates, âwas because at the time I had the no angel rule â I just didnât want them. I had this notion in my head that the only forces of good in the universe were humans, and that it was sweaty, disheveled, confused humans up against this overwhelming supernatural threat. But in humanity lay the power and the ability and those tiny moments of grace which allowed good to triumph. Thatâs my world view and itâs what I wanted to attribute to the show. I didnât want massive supernatural creatures, who were good, to come in and save them. Salvation has to lie with your main characters, or else whatâs the point? So Iâd been very resistant to the idea, but then in between seasons three and four, I was thinking about the problem of how demon mythology was just getting kind of boring for us. Every time a demon came up as an episode idea [in season three], my co-show-showrunner, Bob Singer, and I always sort of sighed and said, âAlright, what are we going to do with the demons this time?ââ But then Kripke had an epiphany. âI was just puttering around my house,â he says, âjust stewing on the problem of what to do besides demons, and wondering, âHow can we possibly expand and twist our mythology?â I remember the moment, I remember where I was in my house, and I remember the thought clear as a bell: âWell, if youâre looking at it purely in a yin-yang way, if youâre looking at two sides of a coin, angels are the other side of the demon coin.â Then one of my first thoughts was of Christopher Walken in The Prophecy â âWell, you know, you can do angels where theyâre not good guys. You can do angels as nominally good in that theyâre fighting for Heaven, but theyâre soldiers.â I started thinking about the smiting of the first-born, and of Sodom and Gomorrah. I was considering all that and I thought, âWell, you actually could have angels and have them be truly terrifying.â To give credit where creditâs due, itâs Sera who showed me the poems by Rainer Maria Rilke about how scary angels could be, so in the back of my head there was already this notion that angels in their true forms were such overwhelming powers that they could be really terrifying. Along with the realization that angels could actually work on Supernatural, Kripke also realized that more than that, they needed the angels. âWe were attempting to have this massive off-camera scope of the universe in which these sides were battling each other, but we only had one massive side,â explains Kripke. âWe had the evil side, the demons. And then we had our hunters. With our production, we couldnât afford the size of demon-human battles we wanted, we just didnât have the ability. But what the angels give you is the other army. Now suddenly we can have these massive off-camera clashes. And massive off-camera drama that you can bring into the storyline that you never have to see, you can just reference in dialogue. With that, the world started to feel more epic and much more of the Star Wars/Lord of the Rings-on-a-budget mythos we were going for. We could have this massive war between angels and demons, but the story could still be about these two Midwesterners in a muscle car. It just gave us so much more territory to steer through and around.â âThe other thing it did is for the first time it made Dean a coherent and central part of the mythology. Weâd always had Sam being the dark sideâs chosen one, but it never occurred to us to say, âWell, maybe Dean is the chosen one of the light side!â Now he isnât just a bystander to Samâs mythology, and that provided much more of a story engine.â âI walked into the writersâ room on the first day of season four and looked at the writers, who up to that point had taken to heart my very staunch no angel stance, and I said, 'Okay guys, angels⌠but theyâre dicks.âââ
