Things We Hope to See in the Supergirl Season 3 Premiere

SANVERS

After today's revelation that Floriana Lima will be reducing her role on Supergirl in season 3, it seems more important than ever to get a satisfactory resolution to the marriage proposal that was made at the end of season 2.

Less Maggie next season means less screen time for the audience's favorite couple, but we're hoping that the relationship isn't just discarded as the Kara/James dynamic was at the start of the show's sophomore year.

There doesn't seem to be a perfect answer here: they built up such a compelling relationship in season 2 that the idea of losing Lima as a regular presence is going to hang like a shadow over the series going into the fall.

Another wrinkle is that the role was apparenlty never designed to become a permanent part of the series. Per a tweet from Lima earlier tonight, "While this role was only meant for one season, I'm excited to appear in season 3, as we see the #Supergirl story unfold #Sanvers #NotOverYet"

So it's not over yet...but things are unlikely to be as fleshed out next time around. Let's get a really satisfying premiere in so that if season 3 doesn't deliver on this front, the story at least got a satisfying cap on it, as opposed to the dangling proposal.

CADMUS

What happened with the Cadmus plot? After the organization lost Lillian Luthor, we were never 100% sure whether it was shut down, or whether other people -- perhaps Jeremiah Danvers? -- simply took it up in her absence.

Let's see what's been going on with them, and what their current direction is. In the second half of the season, writers didn't seem to know what to do with Cadmus as the threat of Rhea loomed. The story kind of limped along since the first false-start on "solving" the problem around midseason, and while it's certainly gotten more interesting once the human supremacists found themselves dealing with an honest-to-God alien invasion, it's not something we'd like to see hang around as a constant, looming threat.

Besides the general Cadmus-as-a-threat side of things -- which maybe could be resolved by putting somebody with a moral compas in charge fo the organization and allowing it to blossom into more of what it was in the comics, rather than simply dismantling it -- there are other aspects of the Cadmus story that need to be dealt with, as well:

• What to do with the Cyborg Superman? Henshaw Classic was an intriguing inclusion, but as nothing but Lillian's flunky and some of the worst special effects on any superhero show currently on TV, he feels a bit wasted. Giving him some sense of direction, so that he could be a threat or even an uneasy ally in future seasons, would be ideal...but failing that, just get rid of him.
• See also: Lillian Luthor. Playing her off of Rhea this season gave the splashy revelation that a Luthor was behind most of the season's badness a solid reason for being, but once the Rhea story is played out and Lena can see that her mother truly, absolutely does not share her value, it seems like somebody as smart as Lex Luthor's sister would know better than to be played again. Obviously, that could lead to a whole different dynamic with Lillian -- either one where the two are more honest with each other, or one where Lillian resents Supergirl for having helped to drive them apart...but either way, we're hoping for a new chapter in this relationship, because we've been stuck on the same page for a while now.
• And Jeremiah Danvers. He's been good, bad, indifferent, loyal, and traitorous. It's hard to know what to make of the Danvers patriarch...but at this point it would be a crime not to give the family some resolution on that plot point, and at least let them start building toward acceptance of what Jeremiah has become.

CATCO

The Cato environment, the single most important setting in season 1, was all but gone in much of season 2.

Even as Kara's burgeoning career as a reporter frequently took center stage, she would be working in the field, or collaborating with Lena Luthor, rather than spending a lot of time in the actual CatCo offices.

Meanwhile, what that means is that the audience hasn't seen much of the office during a time of massive changes there: James took over Cat's office and role, and outside of a little bit about how hard it is to be an untested chief executive, we got very little look at the fallout from that.

Cat, when she returned, wasn't happy to see the state of her office, and she openly suggested that she was here to stay during her TV appearance in "Resist."

Given her symbolic importance and her one-on-one antagonism of Rhea, Cat is a charcter who we could very easily see making a Noble Sacrifice in the finale, although we really hope not.

Either way, we hope that the CatCo story gets a little bit of traction next season, and that whether or not Cat decides to stick around next season, James and Snapper have a little more to do.

LEGION

It's been about a year sine we first saw the Legion of Super-Heroes flight ring in Superman's Fortress of Solitude, and six months since there started to be a whole lot of evidence -- and a lot of people, from DC All Access to set designer Tyler Harron to guest director Kevin Smith -- indicating that the Legion was on the way eventually.

At this point, let's see it!

We've already got a pretty good working theory about just how the Legion might come into the picture -- and the clues have been laid in effectively enough this season that many fans will likely be bummed if it doesn't happen.

The Legion of Super-Heroes is a team of teen-aged superheroes from a thousand years in the future. Headquartered on Earth, they come from a variety of different worlds and have a variety of different powers (although each of them wields a Legion flight ring, which provides its wearer with a universal translator, the ability to fly, and some other perks).

Inspired by the legend of Superboy, the Legion traveled back in time to recruit Superman as a teenager, and would periodically steal him away to the future to have adventures with them, returning him to Smallville when they were done. At different points, the post-Crisis on Infinite Earths Superboy (Conner Kent) and Supergirl have also been part of the Legion.

Once one of DC's most successful and popular franchises, the Legion of Super-Heroes have suffered quite a bit since the first line-wide continuity reboot following 1986's Crisis on Infinite Earths. At that time, Superman's backstory was modified so that he was never Superboy and the Legion had to modify its own backstory to accommodate, "invalidating" many of the stories that pre-Crisis Legion fans had loved. The character who took Superboy's place in those retroactively-altered tales, though? Mon-El, the Daxamite hero often known as Valor.

While he did have his own ongoing series set in the present day for a while, and participated in the World of New Krypton storyline which also took place in the then-current DC Universe and was the clear inspiration for this whole "New Daxam" idea, most of Mon-El's memorable stories have taken place as part of the Legion of Super-Heroes, so when he came on board, many fans wondered whether it was just a matter of time before we would see the rest of the Legion.

MORE SUPERGIRL

SUPERGIRL is an action-adventure drama based on the DC character Kara Zor-El, (Melissa Benoist) Superman's (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents' help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret.

Years later, Kara was living in National City and still concealing her powers, when a plane crash threatened Alex's life and Kara took to the sky to save her. Now, Kara balances her work as a reporter for CatCo Worldwide Media with her work for the Department of Extra-Normal Operations (DEO), a super-secret government organization whose mission is to keep National City – and the Earth – safe from sinister threats. At the DEO, Kara works for J'onn J'onzz (David Harewood), the Martian Manhunter, and alongside her sister, Alex, and best friend, Winn Schott (Jeremy Jordan). Also in Kara's life are media mogul Cat Grant (Calista Flockhart), James Olsen (Mehcad Brooks), a photo journalist who moonlights as Guardian, a masked vigilante, Lena Luthor (Katie McGrath), and Mon-El of Daxam (Chris Wood), whose planet was ravaged by Krypton's destruction. As Kara struggles to navigate her relationships and her burgeoning life as a reporter, her heart soars as she takes to the skies as Supergirl to fight crime.

Based on characters created by Jerry Siegel and Joe Shuster, SUPERGIRL is from Berlanti Productions in association with Warner Bros. Television, with executive producers Greg Berlanti ("The Flash," "Arrow"), Andrew Kreisberg ("The Flash," "Arrow"), Sarah Schechter ("Arrow," "The Flash"), Robert Rovner ("Private Practice," "Dallas") and Jessica Queller ("Gilmore Girls," "Gossip Girl," "Felicity").
