In a single hour of Supergirl, writers Derek Simon and Jessica Queller grapple with racism, homophobia, and xenophobia through both metaphor and reality. Instead of going the original X-Men route where Stan Lee used a team of white teenagers to explore racism in the United States, Simon and Qweller deal with it head it on in pointed speeches from J’onn, who mentions how being taking the form of an African American man has had an impact on how he is treated, and new supporting cast member Maggie Sawyer (Floriana Lima), who talks about how growing up lesbian and Latina in Nebraska, has caused her to connect with the more extraterrestrial citizens of Metropolis. Rachael Talalay’s (Doctor Who, Tank Girl) direction of the scene captures why science fiction and superhero stories have captivated people of color and LGBTQ folks as she lovingly closes in on the different features at the aliens at the bar. Chyler Leigh (who plays Alex Danvers) also has magnetic chemistry with Lima, and even though, they are chasing a lead on a possible Kryptonian assassin of the president of the United States (played by a a positively regal), it seem like they are on a date at a gay bar. Text and subtext mingles to create an over the top, yet wonderful episode of Supergirl.

The main plot of “Welcome to Earth” is centered around the signing of the Alien Amnesty Act, which allows all extraterrestrials to become American citizens. There are overt parallels with the amnesty towards undocumented immigrants in the United States, and both the real policy and Supergirl one are connected to the fact that the United States is a nation of immigrants from all over the world. However, instead of having Supergirl fight against some xenophobic figurehead, Simon and Queller have her confront her own implicit racial biases towards Mon El (Chris Wood), who is from Daxam, a planet that was involved in a civil war with Krypton years ago. While Mon El is being held in DEO containment, Kara basically tells him that Krypton is a more “enlightened” planet than Daxam, which characterized as a lawless, warlike land. She is the good guy, but this is flat out racism. This scene is painful to watch, but shows that everyone (Even paragons of virtue like Supergirl.) have biases and prejudices that we need to overcome. This is in spite of Mon El’s inclusion in the plot being your usual run of the mill red herring deal as it’s revealed that an alien named Scorcher is behind the attack on the president.

Scorcher is the weak link of this episode. Her powers look cool, but there is really no substance to her character. She is just there so Supergirl and the DEO have something to fight and investigate. But Simon and Queller don’t revert to superhero comic politician cliches with the president’s reactions to her attack as she (slightly naively) continues to push the Amnesty Law even when she is attacked by an alien twice. These attacks are also a chance to show Supergirl’s unflinching heroism as Talalay zooms in on shots of her covering the president with her cape, or carefully using her freeze breath to make sure that the Amnesty Act is unharmed. It’s unfortunate that Scorcher is a pyrokinetic plot device, but she is a small setback in an episode filled with real world connections underneath a warm sci-fi veneer. Plus Lena Luthor returns in this episode and shows the signs of being a possible, excellent Big Bad as Katie McGrath delivers her lines to Kara with a casual friendliness even as she channels her inner Donald Trump and says that humans must have the ability to detect the aliens among them. Lena has the makings of a great villain because she thinks she is helping out (and making a buck) with this new technology, and because she isn’t impulsive like Metallo or Scorch, but quite the chess player.

Supergirl also continues to do an excellent job showing the difficulties that Kara has in her day job while also finally giving James Olsen some scenes that channel his undeniable charisma in Season 1 as he and Snapper Carr butt heads. By the end of “Welcome to Earth”, it is clear that he is the boss as he rewrites Carr’s choosing to take a moral stand instead of hiding behind the cloak of objectivity. Snapper does get to show off that he’s a journalist’s journalist as he pursues all angles (including religious) of the Amnesty Act and helps Kara channel her passion for the truth while filtering out her “pro-alien” bias to be an objective reporter. It’s nice to see Kara learn the craft of being a reporter instead of just using her day job as a way to set up plots, and the bias discussion with Snapper dovetails with a conversation she has with Mon-El where she admits her bias towards his planet.

Maggie Sawyer is truly a great addition to the supporting cast of Supergirl as she instantly connects with Alex Danvers with their similar take charge attitudes as they try to one-up each other at the scene of the attack on the president.. And on her own, she fills in a gap in Supergirl as she is connected to both the human and alien citizens of National City in her job as a police officer. She also happens to frequent an alien bar and be the ex-girlfriend of a certain prominent DC character, who gets revealed in a gorgeous flourish of CGI and yet another tense confrontation scene from Talalay. Talalay builds the connection between Maggie and Alex through glances similar to the looks Cate Blanchett throws Rooney Mara’s way in the 2015 LGBT indie film Carol. Add some sharp banter, and the fact that Maggie helped Alex have a more sympathetic view towards aliens and see them as nuanced individuals, and we have the start of a beautiful friendship, er, romance.

Supergirl soars to new heights in “Welcome to Earth” as Derek Simon and Jessica Queller pay tribute to the Super-mythos’ immigrant roots while taking racism, xenophobia, and homophobia head on through superpowered metaphors as well as great characters, like Maggie Sawyer, J’onn, Mon-El, and even Supergirl herself, who confronts her flaws in this episode while continuing to be adorable, especially in her interactions with Lynda Carter’s president, who is an alien herself…
