How Did Supergirl Solitude Tie Into The Supergirl Movie?

Warning: Spoilers ahead for tonight's episode of Supergirl, titled "Solitude."

Tonight's episode of Supergirl opened up the universe and mythology of the show in a huge way.

We saw some things, both inside and outside of Superman's Fortress of Solitude, which are virtually guaranteed to have long-reaching impact on the series, and at the very least which tease some really interesting stories to come and some cool backstory hidden away inside of the existing text of the show.

One such piece of mythology was the revelation that Non was using The Omegahedron at the end of the episode.

What's the Omegahedron, you ask? Well, if you're a longtime comic book reader...

...you might still be clueless.

Yep, it's that kind of thing.

The Omegahedron actually comes from the 1984 Supergirl movie directed by Jeannot Szwarc and set in the world of Richard Donner's Superman films.

Of course, the fact that Donner's vision for the Man of Steel heavily influences Supergirl is nothing new...and neither, actually, is the fact that there would be a tie to the Helen Slater-starring feature film.

"That Supergirl movie obviously has its many flaws but when I was a kid, I didn't realize those flaws as much and I used to watch it all the time," showrunner Andrew Kreisberg told me in an interview back in November. "There's a couple of shout-outs to the Supergirl movie coming up that I think the fans are going to be excited about."

Could this be what he meant? It doesn't seem unlikely.

For those who haven't seen the not-entirely-beloved film, The Omegahedron is one of two great power sources vital to Argo City in the Supergirl movie. Along with its partner, the Alphahedron, the Omegahedron powers the entire city, its devices and provides its people with light, heat, air, and all the things necessary to survive. Its power is seemingly limited only by the imagination of the user, and it can do things like creating a simulation of life, or bringing the greatest desire of the user into reality.

What will Non use it for? Is that really Indigo it brought back, or just "fancy shadow of the real thing?" Those, and many more questions, will likely be answered soon...!
