Catra fought against her restraints, but she isn't unable to do so. She is currently on her way to be banished to Beast Island for failing Hordak for the last time. Once the boat went for its destination, two Horde soldiers removed her restraints and tossed her to the island before taking off. She is left here to be marooned, and whatever happens to her afterwards is left to anyone's imagination.
She doesn't know what to do. She has heard the rumors of the dangers lurking in Beast Island, mostly about monsters.
What she is going to do now?
Hearing the rustling from the bushes made her want to investigate the source, and it came a person. Not just any person, but it's someone who looks just like her. On top of that, she wore clothes of royalty as if she rules the place.
"Who are you?" Catra asked, going into a defensive stance in case she tries to attack her.
"I'm C'yra. Queen C'yra of Half Moon," was the reply.
"I know you!" hearing her name is enough to trigger memories that she isn't supposed to remember. "You're the person in my dreams. I saw you having a baby, and Shadow Weaver took it away from you."
"So it's true. It is you," C'yra realized.
The two stared into each other's eyes, and before they know, tears started coming out of her eyes. They started recognizing each other at this very moment.
"Catra?" C'yra cried first.
"Mom?" Catra cried next.
They run straight toward the other and wrapped each other in a hug, happy to have the reunion they deserved for so long.
"The Horde took me away from you. She took me away from you," Catra cried to release all the pain that she felt, especially when she realized that she was the baby that was taken away by Shadow Weaver.
"What does it matter? All that matters is that you're home, my princess," C'yra comforted her saddened girl.
So it's true. If her mother is the queen, then she must be the princess.
Princess of Half Moon.
"Are you ready to see your people, Catra?" C'yra wiped off her tears after letting go of the hug.
"Yes, I'm ready, Mom," Catra did the same thing. She knew that if she has a mother, then this must mean her people must have survived the Horde's assault on them.
They walked their way to the castle that was located on the island, and the others who look just like them not only saw their queen, but also their lost princess.
"Welcome home, Catra," C'yra said with a smile on her face.
Author's Note: Just something I think of what would happen post-season 2. Like I said, I did my best.
