Rhea uses Silver Kryptonite to manipulate Kal's senses, causing Kara to appear to be General Zod. Kara eventually overpowers and takes him to the Fortress, where a recovered Kal finds a way to end the invasion. Kara challenges Rhea to Dakkam Ur, a rite in which two leaders duel and the loser concedes the war, accepted by Rhea. Lillian, Lena and Winn build a device to disperse lead into the atmosphere. As lead is lethal to Daxamites, it would make the planet uninhabitable to them. With Mon-El's approval, Kara tells the DEO to use it if she loses. During the duel, Rhea resumes the invasion. M'gann returns with other benevolent White Martians and J'onn awakens to join the battle. Rhea claims the invasion will not stop even if she loses, so Kara launches the device, killing Rhea and forcing the fleet to leave. Kara puts Mon-El in a pod and sends him away from Earth. Cat reassumes her position at CatCo and Alex asks Maggie to marry her. In deep space, Mon-El's pod is drawn into a wormhole. In flashbacks to Krypton's destruction, an unknown faction sends another infant to Earth in order to "reign."

M'yrnn gives J'onn one final memory before merging with the earth to stop the terraforming and the heroes defeat the priestesses. Sam finds the fountain in Juru and makes peace with her mother. She drinks from the fountain and defeats Reign using the sword. However, this leads to Sam, Mon-El, and Alura dying, so Supergirl goes back in time and changes the outcome of their fight using the Harun-El. Brainiac 5 decides to stay on present-day Earth because a distant relative (who did not die in the Blight) has started wiping out all other AI and asks Winn to take his place with the Legion. Winn accepts his offer and travels to the future with Mon-El. J'onn steps down from the DEO and promotes Alex as director. Kara decides to stay on Earth instead of returning to Argo with her mother. Sam, completely rid of her Kryptonian side, returns to her life with Ruby. Lena gives Alura all of the Harun-El and a mathematical formula to create more, but synthesizes a portion for secret experiments. A duplicate Kara appears in Siberia at the same time Reign is defeated with the Harun-El.

Notes

  1. 1 2 Following the November 2015 Paris attacks, the episode "How Does She Do It?", which features content similar to the attacks and was originally scheduled to air as the fourth episode of the season on November 16, 2015, was pulled from its scheduled airing. In its place, the episode "Livewire", which was originally scheduled to air as the fifth episode on November 23, 2015, was aired.[10] "How Does She Do It?" then aired as the fifth episode on November 23.[11] For the season's home media release, the episodes were restored to their original production order,[12] which is how the episodes are presented here.
