"Should I get a blowout?"

Not even Supergirl was immune from "meeting the President of the United States" jitters in the latest episode, "Welcome to Earth." Anytime I think Kara Danvers couldn't be more relatable and endearing in Supergirl, she proves me wrong. As Supergirl, one of the most powerful beings on our planet, she has no reason to be nervous and yet... We've watched Kara grow into her powers and understand how to best help people, but I appreciate that becoming Supergirl hasn't changed her.

As much as Kara has learned, she still has some lessons ahead. We see her grapple with a hugely important one here: acceptance. On one hand, she lauds President Marsdin, who by the way, is portrayed by none other than Lynda Carter, for bringing the Alien Amnesty Act to fruition. J'onn is hesitant, but Kara supports the move without question. She argues not all aliens are bad and that we should welcome them and grant them the same rights every American citizen has. Yeah, it's a topic incredibly relevant to our current political environment—I'm not going to go there beyond saying that the truth Supergirl butts up against throughout the episode is one we all need to chew on.

Acceptance. It's the least any of us deserve. The President's act offers America's open arms to any aliens that come seeking refuge. Kara's behind the President. And then when Kara learns about Lena Luthor's alien detection device, she's outraged that it would single out aliens. Not everyone shares the President's views; many would shun planetary outsiders. Kara looks like she's going to have a panic attack at her true DNA being discovered. However, as soon as Kara realizes the stranger that crashed to Earth in a pod is a Daxamite, she sheds all semblance of tolerance.

Kara immediately leaps to the conclusions she chided others for having. Her attitude toward all Daxamites being horrible was single-minded and not at all in line with her earlier actions. Her personal experiences with residents of Daxam blind her to other possibilities. C'mon, Supergirl, you can do better than this. You can be bigger than this. Especially when you consider that, like her, the Daxamite is a man without a home.

Kara does come around to realizing her mistake in the way she treated the Daxamite, a.k.a. Mon-El. It wasn't a result of navel-gazing so much as her having another misbehaving alien explode in her path. That alien tried to assassinate the President, and Kara had blamed the first attempt on the President's life on Mon-El. The event made her open her eyes and remember to be kind. That combined with acceptance is something all of us can do every single day.

Cheesy? Sure. True? Most definitely.

I can't move on to #DCTV secrets in "Welcome to Earth" without spending a moment on the alien safe haven. It was like visiting the Mos Eisley cantina in Star Wars. Dropping in with Maggie Sawyer gave both Alex and us a look at the range of aliens on Earth. I didn't fully realize the population stretched beyond former Fort Rozz prisoners. This dive bar broadens the world and gives characters such as J'onn a place to shed his disguise and try to connect. He was just as prejudiced as Alex and Lena. Plus, what a fine locale to meet one M'gann M'orzz...

Let's turn our attention to some #DCTV Secrets, shall we?

Mon-El goes to Mt. Pride Observatory to try to send his distress signal to Daxam. The location has appeared in DC Comics history, specifically in JUSTICE SOCIETY OF AMERICA in the early '90s.

And speaking of Daxam, Daxamites were former Kryptonians who left their home to explore the galaxy at large. When exposed to the yellow sun of Earth, they gain powers similar to Kryptonians, but instead of being vulnerable to kryptonite, they're vulnerable to lead. The character Mon-El was a Daxamite in the comics and first appeared in SUPERBOY #89. His name came from Superboy, because the kid found him when he came to Earth—Mon because he arrived on a Monday and El because Superboy thought they were related. Years later, after a near fatal encounter with lead, Mon-El eventually joins the Legion of Super-Heroes.

One more quick secret: Did you catch the President's reference to her "other jet?" When she portrayed Wonder Woman, Carter piloted the character's invisible jet more than once.
