This review contains spoilers for the third season of Supergirl.
The third season of Supergirl is focused on family, including the families the characters have built for themselves. Cat Grant is now gone (she’s the press secretary to the president, played by Linda Carter). Lina and Kara are friends, and when conservative jerk Morgan Edge threatens to purchase Catco in a hostile takeover to stop them from publishing the truth, Lina steps in and buys Catco instead. Lina initially tries to be hands-on with running Catco, but James Olsen the managing editor and Lina’s boyfriend convinces her to step back a bit. Edge at one point tries to get back at Lina by accusing her of poisoning the children of National City with lead. Supergirl proves that the children are sick because of chemicals in the city’s swimming pools – chemicals produced by Morgan’s company. There are mutual accusations of attempted murder as well, but Lina isn’t guilty and it’s implied neither is Morgan.
J’onn J’onzz receives a message from M’Gann to come to Mars. He goes with Supergirl and they find a White Martian resistance who have discovered J’onn’s father being held, prisoner. They release him and J’onn brings M’yrnn J’onzz back to Earth. M’yrnn initially stays at the DEO, and then in J’onn’s apartment. However, sadly, M’yrnn is suffering from a Martian form of Alzheimer’s Disease. There are a lot of ups and downs in J’onn and his father’s relationship. In the end, J’onn accepts his father is dying and prepares for “The Reach” a Martian mental passage where all of M’yrnn’s memories and experiences will be passed to his son.
Alex and Maggie Sawyer prepare for their wedding. Alex even finds Maggie’s family who abandoned her when they learned she was a lesbian. Maggie’s reunion with her father seems to go OK, but in the end, he rejects her again. Alex comes to realize that she really wants to be a mom, whereas Maggie doesn’t want children. The two reach an impasse and break up – and Maggie is never seen again. Alex is understandably hurt by this throughout the rest of the season. In the last few episodes of the season, she’s starting to research adopting a child.
Morgan Edge orders an attack at the unveiling of National City’s waterfront Supergirl statue and a young mother, who had bumped into Alex earlier, uses incredible strength to move a fallen metal pipe from her daughter. Alex, Lina, and eventually Kara become friends with Samantha and her daughter, Ruby. Sam works with Lina at L-Corp and is promoted to Chief Financial Officer after Lina buys Catco and steps back from the day to day running of L-Corp. Some weird things happen to Sam and Ruby. Slowly through the season, it becomes obvious that Sam’s blackouts and losses of time are related to the appearance of a new supervillain, Reign – the Kryptonian Worldkiller. Sam/Reign is an oddly sympathetic villain. Sam has no idea what her other half is doing. Sam’s a struggling single mother, trying to balance a demanding new job with raising her 12-year-old daughter. Sam and Ruby have a good relationship, but Ruby is a bit put out that her Mom doesn’t spend as much time with her as she used to. And Sam doesn’t know she is Reign – a supervillain capable of beating Supergirl badly and putting her in a coma.
I had a couple issues with the episode where Reign beats up Supergirl and puts her in a coma. First, I’m a little tired of the pattern – new villain beats up Supergirl, but by the end of the season, Supergirl will defeat the villain. Second, since Kara is in an honest-to-goodness coma and severely injured, Alex should have contacted Clark (Superman). Clark is her cousin, he has a right to know she’s been so seriously hurt. Alex also should have contacted Eliza, she also has a right to know what happened.
Kara is in a funk during the first half of the season because she had to send Mon-El away. Mon-El comes back from the future with a spaceship and his team-mates in the Legion of Superheroes, Brainiac 5 and his wife, Imra. Mon-El’s ship went through a wormhole and he had lived for seven years in the future. The Legion was sent back in time with multiple missions, some of which Mon-El doesn’t know about.
Once Mon-El, Brainiac 5, and Imra arrive, Supergirl and her team are able to learn more about Reign and the two other Worldkillers: Purity and Pestilence. The Legion really wants to destroy Pestilence because in their time she evolves into a being called Blight which is responsible for the destruction of whole planets and everything on them: people, animals, and plants. Lina also, as a friend of Sam’s, wants to help. Lina realizes that Sam is Reign, but that she has no knowledge of her other half. Lina even explains that Reign is over-writing Sam’s DNA, a process that if it continues will cause Sam to be Reign all the time, eventually killing her own personality. (We see this process happen quickly with Pestilence.) Lina keeps Sam in a secret lab at L-Corp and at first tries to figure out what is wrong with her and later tries to fix it. Lina also arranges for protective custody for Ruby while her mother is sick.
Despite Lina’s best efforts – she doesn’t tell Kara, Alex, or Supergirl what she is doing. When the DEO tracks Reign and finds out that Lina’s been trying to stop her – Supergirl especially is very upset, though Alex is also angry. Lina is invited to continue working at the DEO and Reign escapes. There is now considerable tension between Supergirl and Lina – though Lina is still friends with Kara. Yes, this seems to be setting up future conflict.
The story with Reign gets more and more complicated. At one point, Sam is locked in a dream state of a dark, dead valley on Krypton. Kara recognizes this valley. Reign decides to kill Ruby to assure her success – but a threat to her daughter is the one thing Sam can’t handle and it makes her own internal struggle stronger. Kara and company think they have killed Pestilence and Purity at one point, but the audience sees their spirits being absorbed by Reign. Lina realizes they need a special element to stop Reign, but there is no more of it on Earth. Supergirl and Mon-El travel to an “asteroid” to get some but it turns out to be Argo City. Kara meets her mother (now played by a different actress). After an argument with the council, Kara succeeds in getting some of this element. The DEO uses it to “defeat” Reign and Kara and Mon-El return to Argo City so Kara can spend time with her mother. However, Serena, a council member turns out to be the leader of a cult of three Kryptonian witches. They steal Mon-El’s ship and head to Earth to raise the Worldkillers and terraform Earth into New Krypton.
It takes all of the DEOs resources, including help from Lina, Alura (Kara’s mother), Mon-El, Brainiac 5, the other Legionnaires, M’yrnn, and everyone else including Sam to stop Reign. They succeed, but M’yrnn gives his life. Sam lives and is reunited with Ruby.
After Reign’s final defeat and M’yrnn’s death – J’onn decides he needs to spend more time around normal human beings and not stay cooped up at the DEO – he promotes Alex to director of the DEO. Alex, who was wondering how’d she balance her active and dangerous agent lifestyle with adopting a child is happy to take a more desk-bound position. Lina expresses friendship with Kara but anger at Supergirl for betraying her and not trusting her. Mon-El has to return to the future – and takes Winn with him, though it looks like Brainiac 5 will remain behind at the DEO.
Season 3 of Supergirl was a bit dark, but the show is still very good. I liked the female friendships in this season, though the end of season rivalry between Lina and Supergirl was a bit annoying (I hope they do not become enemies next season). Recommended.
