Hordak wants Catra to get rid of Shadow Weaver. Catra objects which angers Hordak. He's got a new bestie, Entrapta. He gives Catra two days to get information out of Shadow Weaver, after which she needs to send her to Beast Island.
Catra, Scorpia, and Entrapta are in the snowy Northern Reaches looking for First Ones technology when She-Ra, Glimmer, Bow, and Sea Hawk show up. Catra is freezing cold and doesn't want to be there. Scorpia has a big crush on Catra and is trying to work up the nerve to ask her out. Entrapta is consumed by the search for First Ones technology.
Adora and the Princess Alliance work on plans to retake a tower that the Horde captured. The planning session begins with just Adora, Bow, and Glimmer but soon expands to include Mermista, Perfuma, and Frosta. They each have their own ideas about how to attack the tower. Each person's story is told is a different animation style.
Adora, Glimmer, Bow, and Swift Wind head to Alwyn to find out what happened there. They think it might have been over run by the Horde but there is no one there. They arrive at night. It is very spooky. There's no one around but they see strange lights and start hearing voices.
The Horde officially takes over Dryl, Entrapta's home. Bow tells Glimmer that he figured out that Entrapta must still be alive. They assume that she must be the Horde's prisoner and go looking for her. They go to Dryl and learn that Entrapta is indeed in the Fright Zone but they don't realize that she is working with the Horde voluntarily.
A month has passed since the Battle of Bright Moon. Glimmer, Bow, Frosta, Mermista, and Perfuma have been busy fighting the Horde's bots in the Whispering Woods while Adora trains within the Beacon. She has learned how to transform her sword when she wants to but quite frequently it transforms into things that aren't very helpful like a flute or a mug. The Princess Alliance is able to defeat the bots day in and day out but they don't have any time left to do anything else significant.
