Superwoman Season 2 Episode 22 Synopsis:

Carla and Clark had a fight. Carla tried to wake Clark up, but failed. During the fight between Kara and Clark, Rhea tells Kara that she controlled Clark with silver kryptonite, and now Kara is Clark's enemy zod in Clark's eyes. Kara and Clark flew from the spaceship to Nash, and finally Kara defeated Clark. Alex arrived, and Carla took herself, Alex and Clark to the lonely fortress with her last strength. Carla and Clark are asleep, and Carla had a dream there. Carla dreamed that none of this happened, and that she and Meng were still fine. Carla and her mother are lying in bed. Carla told her mother's story. Carla woke up and Clark was out of Rhea's control. Things are getting worse. Rhea wants to attack the earth, but they haven't found a way to defeat Rhea. Finally, Clark thought of a way, which is the oldest way. Carla and Rhea returned to the Super Investigation Department. Meng was glad that Kara came back safely, but the next second Meng began to worry, because Kara decided to make the final decision with Dakenfa and Rhea. It's good that Kara beat Rhea, but what if Kara is beaten by Rhea? Clark and Kara are practicing in the room. Professor Clark gave Kara many new tricks, just then Ron woke up. Ron dreamed of Megan when he was in a coma, and Megan woke Ron up. Ron knows Carla very well. Carla didn't want people in Nashville to see her arguing with Rhea, so Carla and Clark went to see Grant, who had decorated her office. Grant agreed to Carla's request and stopped the broadcast of the decisive battle. Lillian found Lena and accused her of believing in aliens. Lillian brought a device, which was set by Lena's brother. It can launch kryptonite against Kara, but now Lillian wants Lena to transform it into a device that can launch lead, so that they can drive away the Daxsam people. Lena agreed, but it will be up to Carla to decide whether to turn on the equipment or not. The decisive battle began, and Kara gained the upper hand, but then Rhea began to use despicable means. She used silver kryptonite, and Rhea broke her word. She ordered the attack on Nash to begin. Kara couldn't hold on, although everyone began to work hard at this time, and Megan also helped to return to Earth. Carla chose to turn on the equipment, and the air on the earth was immediately covered with lead. The Daksham people couldn't hold on. They left the earth and Rhea died on it. Meng couldn't hold on any longer. She had no choice. Carla sent Meng away. Before leaving, Carla gave Meng the necklace left by her mother. When they broke up, Meng told Kara that he would definitely come back, and he would definitely become the person Kara wanted him to be. The crisis of the earth was lifted, and Megan left the earth. After Monk left, Carla was listless all day. Everyone wants to persuade her, but they won't say anything. Finally, one day Kara was persuaded by Grant, and Kara decided to be herself and serve the earth instead of being depressed like this. Not only did Carla come out of her grief, but Alex proposed to Maggie, and Maggie said "I do".

As for the final ending of the whole superwoman, it depends on how the screenwriter writes it. At present, I'm afraid the writers themselves don't know.
