Much of Supergirl has been about establishing Kara Danvers as a hero in her own right, and as a hero the people of National City can count on.
Before even introducing Superman as a recognizable character, we saw Kara fight to prove she didn’t need her cousin to come save the day for her. It’s safe to say Kara’s proven to everyone she’s just as capable, if not more so, than Superman. So would it be a mistake to bring in Superman to be at Kara’s side during the Worldkiller fight?
With the third Worldkiller finally active, and the Legion’s mission to come back to Supergirl’s time and stop her before she turns into Blight revealed, Supergirl showed a clash in ideology between Imra (Saturn Girl) and Kara.
As they attempted to unveil the identity of Pestilence on Supergirl Season 3 Episode 16, Imra’s vision of killing the Worldkiller before she left a permanent mark on the world put her at odds with Kara, who just wants to help save those that are stuck within, i.e. Julia.
Lena Luthor’s stance on morality has been the heated debate circling her character since her debut on Supergirl.
Supergirl Season 3 has already returned to this, twice, and forced Lena to entertain the idea of killing someone to protect herself (and others) and consider what she’d be willing to do to keep those around her safe. As we saw on Season 3 Episode 12, Lena ultimately decided to save Edge from her mother, rather than kill him herself or let her mother finish him off, but can Lena ever truly stay good?
With a new Worldkiller wandering National City and disease quickly spreading, Supergirl and the Legion team up to hunt down Pestilence and discover who is behind these heinous acts.
On Supergirl Season 3 Episode 16, “Of Two Minds,” Kara and Imra clash over their plans to defeat Pestilence, while Sam and Lena continue to learn more about Reign and how this “infection” is affecting Sam’s mind and body, but are they any closer to solving the mystery?
After Supergirl moved from CBS to The CW, Lucy Lane went from fully fledged co-leader of the DEO to nonexistent, and her name hasn’t really been mentioned since. Where did she go?
Supergirl unexpectedly dropped Lucy Lane from their lineup of characters after the production move to Vancouver—which probably is due to Jenna Dewan-Tatum’s family being in Los Angeles and reluctance to leave, just like Calista Flockhart—but, really, no explanation for why Lucy suddenly wasn’t helping J’onn run the DEO? Several characters made such an enormous deal about needing a human leader to keep an eye on the alien leader, yet that was inexplicably dropped, too? It’s time to revisit Lucy Lane.
When Winn’s father, Toyman, unexpectedly dies in prison, a Copycat comes to light to maintain his final wishes: Winn will die if his mother goes anywhere near him.
On Supergirl Season 3 Episode 14, “Schott Through the Heart,” Toyman is to blame when his casket combusts at his small, vengeful funeral. Meanwhile, Winn’s mother comes to town, and her arrival puts Winn in danger. Could his father hurt him from the grave?
After the awakening of the second worldkiller, Kara and her friends are finally back, but they’re now faced with death.
On the Supergirl Season 3 Episode 14 trailer, Winn’s father, Toyman, is found dead in prison, but his deadly hijinks are far from over, and Winn is going to end up dead if he’s not careful.
After discovering the human identity of the second Worldkiller, Purity, Kara and Alex are thrown into the season-long debate of whether to stop or save these people, and whether they have any control over the actions of their villainous alter-egos.
On Supergirl Season 3 Episode 13, Purity rises as Julia attempts to fight her way to the surface—as Sam has been doing since her transformation—and Kara and Alex spat over whether Julia is a false identity to mask the true nature of her existence, or whether she’s an innocent bystander in her own body. However, is their conclusion drawn too soon?
Morgan Edge returns to National City to cause some trouble in Lena’s life, but an outside force nearly kills the both of them. Who could it be? Well, of course, it’s Lillian Luthor!
On (one of the most boring episodes of the season) Supergirl Season 3 Episode 12, “For Good,” Lena’s morality is once again called into question after Lillian Luthor attempts to orchestrate events to cause Lena to kill Morgan Edge. She’s definitely going to win the award for Mother of the Year, right?
After discovering a dark priestess from Krypton knows of Reign’s origin and the destiny of the Worldkillers, Kara goes on a mission to find Fort Rozz in space. However, she must put her trust in unlikely allies because the men of her team are unable to join due to a blue star nearby being poisonous to anyone with the Y chromosome.
On Supergirl Season 3 Episode 11, a few ladies team up to find a priestess, someone dies, and Reign’s identity is almost revealed to Kara accidentally; however, the wait for Reign’s true identity to be revealed to the hero is further prolonged.
