Supergirl Season Finale Recap ‘Battles Lost and Won’

The final battle begins. In order to stop Earth from becoming a new Krypton, M’rynn sacrifices himself to stop the terraforming process. Before he goes, he bestows upon J’onn one final memory. He shows his son the advent of the Green Martians. M’yrnn then joins with the Earth’s core, stopping Reign’s destruction. He tries to hold her hostage there, but Reign is too powerful and manages to escape. Back at the DEO, they are trying to figure out their next move when the distress beacon in J’onn ship goes off. In his final moments, Coville realized what he had done and made amends by sending Team Supergirl the location of the evil Kryptonians. Kara, Mon-El, Alura, and J’onn will take the fight to them, hoping that they give Sam enough time in the Dark Valley to separate herself from Reign.

In the Valley, Sam is dying. She isn’t alone, however. Her mother appears before her. Sam doesn’t believe that she’s real, thinking the Valley is just playing tricks on her. Patricia assures her that she is real, instructing her to drink from the correct pool of water. She sings Sam a lullaby to soothe her as she ingests the water. Eventually, Sam realizes that it is her mother and apologizes for everything. Her strength returns and she soon wakes in the real world. Sam flies off to help Team Supergirl, and they definitely need her. Kara has been struggling with the idea of killing Reign, and eventually gives up on her ideals. She goes into the battle intent on killing Reign. When Sam appears, she stabs Reign through the back with a sword, then Kara throws her into the pit. They think the battle is finished, but Reign fights back, pulling free and erratically shooting laser beams. She kills Sam, Alura, and Mon-El before being sucked into the pit. Kara blames herself for what happened, but then remembers Mon-El’s Legion ring. It has the ability to take her back in time. She does so and instead of killing Reign, she and Sam use the stone to go into the Valley. Sam forces Reign to drink from the pool, trapping the Kryptonian there for good. The day is saved and all of Team Supergirl survived.

The season finale really shook things up going into Season 4. First, the Legion returned to help in the final battle, but also come with bad news. Though they stopped Blight, a new villain has risen as a result, a “distant relative” of Brainiac-5’s, who released a plague to kill all artificial intelligence. As a result, Brainiac-5 will stay in the past, while Mon-El and Winn travel to the future and help protect it. It was sad to see Winn go because he has been a part of the team since the first season. As Kara said, he was the first one to know her secret and has kept all of them safe with his technology. He will return in a recurring capacity next season. Second, while the earthquakes were happening, James removed his helmet in order to calm a woman. That act made him realize that he wants to reveal himself to the world. In the end, he unmasks himself as Guardian. Next, Alura will return to Argo City with the Dark Kryptonians, and Kara won’t be going with her. She has finally realized that everything on Earth makes her who she is. Lastly, Alex was about to put in her resignation when J’onn announced he was stepping down as the director of the DEO. He wants Alex to take his place. This means Alex wouldn’t be in the field as often and can focus on starting a family and being happy. J’onn will take the teachings of his father and live among the people.

The final sequence of the episode is when things got even crazier. Lena sent the substance back with Alura that will help sustain life on Argo, including the recipe on how to manufacture more. What they don’t know is that Lena kept the main rock and is continuing to run experiments on it. She calls Eve at the end of the episode, saying they are ready to start phase two of testing. What is she up to? Why was there such foreboding music playing when she called Eve? Then, we get a tease at a major story line for Season 4. While Kara, Sam, and Reign travel into the Dark Valley, another Kara wandered across the Serbian border. This occurs right after Kara uses the Legion ring to time travel, so maybe she accidentally created a copy of herself? There’s no real indication if this Kara is good or bad, but she hardly reacts when the border patrol points their guns at her. I’m curious to see how this is going to play out next season.
