Did the planet just backflip off its axis? Are pigs doing cartwheels across the sky? Did Michael Jackson moonwalk out of his grave and buy a ticket to Shrek 5? Because something impossible just happened: Supernatural based a whole episode around female characters. Three-dimensional ones, even! None of them love interests. And with a recurring character to boot. What show was this? I know, I know, by now all complaints about Supernatural’s casual misogyny — whether by omitting multi-dimensional females or simply fridging them — are admittedly tired by now. But “Alex Annie Alexis Ann” proved that perhaps the complainers were right all along. This was a heavy, thoughtful, and tremendously well-written episode of television, and it couldn’t have been possible without strong female characters. Who knew! Oh, right. We all did.
