In “Changing”, writers Caitlin Parrish, Andrew Kreisberg, and Greg Berlanti round off several characters subplots as James Olsen and Mon-El wrap up their heroic journeys, Alex Danvers comes out to her sister, Supergirl, and Martian Manhunter and Miss Martian are brought closer together in a traumatic way. Oh, and there happens to be a villain in this episode as director Larry Teng pays homage to The Thing with an alien parasite taking out scientists at a remote base near one of the poles in its cold open. Parasite (Lost’‘s William Mapother) that extremists can be on both the left and right side of the aisle. Climate change is terrible, but killing human beings isn’t the solution

But Berlanti, Parrish, and Kreisberg  use Parasite less as a global warming parable in classic Superman villain form and more as a way to cause the cast of Supergirl  external discomfort to go with their inner pain. The strongest emotional beat in “Changing” and one of the best character arcs on a TV show in 2016 belongs to Alex Danvers. Chyler Leigh excels at changing her vocal timbre and has great range as an actor going from aloof to happy to completely broken at the drop of the hat while also kicking ass in the action scenes against Parasite. She doesn’t have to speak to show the depth of her uncertainty about how to talk about being a lesbian, or the depth of her feelings towards Maggie Sawyer. The scene(s) where Alex comes out to Kara are the complete opposite of an after school special as Teng uses soft lighting with a minor piano score from Blake Neely as well as getting rid of Kara’s “glasses disguise” for a true moment of authenticity as she is there for her sister. Alex coming out as lesbian wasn’t a stunt for ratings or titillation, but an organic part of development of a character as she strives to be whole in her personal life as well as her professional life as an agent of the DEO. The ending of her storyline is completely happy, but thankfully Berlanti, Parrish, and Kreisberg go the route of Carmilla rather than The 100 as far as tragic queer characters are concerned.

Last episode, I described Mon-El as “adorkable”, but maybe he is more of a douche than a dork. His storyline in “Changes” starts out promisingly enough with Chris Wood flexing his impeccable comedic timing with Mon-El’s reactions to various aliens sending him drinks at the alien bar, which has become the show’s most memorable setting with Catco being a pale spectre of its Season 1 self. But it all goes to hell after this as Mon-El uses his powers to be an enforcer for an alien bookie and not feel any guilt about it. His amorality has gone from naive to downright frustrating or disgusting, and it’s kind of cathartic to see Alex light into him for using his powers to hurt people weaker than him and call him a coward. Mon-El does pathetically participate in the fight against Parasite as he takes baby steps towards being a superhero. He’s not very likeable though, but his role in the episode’s cliffhanger opens up a possibility for him to regain some face in the long run.

I have mixed feelings about the James Olsen becomes a superhero subplot, and all of Mehcad Brooks’ charm goes out the window when he is covered up behind a helmet and voice modulator. But his transformation into the vigilante Guardian has brought him and Winn closer together as well as added another black superhero to television. Even though he ends up cracking wise in the heat of battle when James battles Parasite while Supergirl and Martian Manhunter are down for the count, Jeremy Jordan plays Winn very seriously in “Changes” as he basically tells James to back off his demands for the Guardian suit. He cares for James and doesn’t want to kill himself while playing superhero. Winn is skeptical about James’ actions and kind of a stand-in for Supergirl fans, who are wary of his arc in Season 2. However, he ends up coming around when he realizes that telling a guy in a suit how to punch and defend himself is kind of an adrenaline rush. Olsen might have the gruff, grating voice of Christian Bale’s Batman, but he and Winn have a genuine good time as superheroes even if his origin story is rooted in the death of his father and his own insecurities as a “sidekick”. Some better sound editing would make the patter on Olsen’s side a tad bit snappier.

Due to dramatic timing (and probably budget constraints), Larry Teng saves the reveal of Rudy Jones’ final Parasite form for the last third of “Changes”. Unlike the shoddy CGI of a recent of “monster” in The Flash, Supergirl”s visual effects artists give him the purple hue of the comic book version to go with intimidating size and scale. The makeup and visual effects team should also be commended for their work on the wounded Martian Manhunter and Supergirl, who look like they’re on death’s door and completely drained of their health and vitality. They definitely don’t look like powerful, adorable superheroes or cool, regal Martians. In the big brawl between Mon-El, Guardian, and this week’s villain, Teng doesn’t neglect the horror giving Parasite a “chest burster” for a mouth that he breaks out when fighting Mon-El on the streets.  His direction (and the writing) does falter a little bit with the quick reveal of a limitless energy MacGuffin that Supergirl gives Parasite to finally defeat him which is even little too much deus ex machina for a superhero show. However, the image of Kara taking on a huge burst of energy that could destroy any of her friends is a visual representation of her ability to inspire James Olsen to become a superhero, Alex Danvers to embrace her queer identity, and for Mon-El to “show up”.

On the surface, “Changes” get its title from the physical transformation that Dr. Rudy Jones endures as he goes from an overzealous scientist to a character in an early David Cronenberg movie to a tricked out supervillain. However, it is truly about the transformations in Supergirl”s well-rounded supporting cast. Some changes are more thoughtful (Alex Danvers) than others (Mon-El), but the episode is another shining example of how Supergirl has reached new heights by focusing on the people behind the icons aka their feelings and not just flying, alien punching, and shapeshifting. All those things are cool though.

Finally, Changes” is also yet another stellar example of how inspiring science fiction and superhero stories can be towards queer people as Kara finds common ground with Alex in their shared “secret identities” as a superhero and queer woman respectively. But Supergirl doesn’t stay in the world of metaphor and strives for nuanced LGBT representation as Alex and Maggie are at very different places, and maybe a romantic relationship isn’t the best option for them right now even though all the fans want them to smooch.

In a country where the government will be run by a man who allowed queer teenagers to be literally tortured and shocked into “becoming straight”,  Chyler Leigh’s portrayal of Alex Danvers is a beacon of hope and a reminder that you can come out at any stage of your life.
