Attack on titan: Another way

Black thing

Thrid pov 

     Cass and Kiah were covered in blood, Kiah having more blood than Cass because she ate a lot of people. Cass looked up her eyes meeting her father's eyes. He didn't have a look of disappoint like he did for her brother, but more like a peaceful one. Then one by one they disappeared showing they were at peace. 

"That's why when ever we were in wall sina I would see them." Cass said with a yawn. 

'How the heck am I tired I just killed someone.' She thinks to herself. She felt Kiah's claws on her. 

"Your tired because you killed him, Killing someone takes a lot of energy. Plus I took over your body that's another thing that'll take your energy." Kiah tells Cass as she slowly falls asleep. 

"Don't worry I'll get you back, It's day so I'll have to be quick." Kiah saids as she carries the girl in a bloody white dress. Kiah went to the side that she came in through hiding in the shadows to get back to where the scouts stayed. It took almost all day, but she got back. Cass was still asleep in Kiah's arms. 

   As Kiah showed up she saw it was only Levi outside and everyone was inside. 

"Levi." Kiah called out. Levi look to see which brat wanted to see him, but he saw a huge black creature then he noticed Cass in it's arms. Levi took the girl as Kiah went back to her normal form. 

"Get some rest Kiah you need it and thank you for getting her, Eren is about to have a fit." Levi said as he goes into the castle holding his team. When Levi entered Eren was the first to look up at him. What he saw made him cry before running to his Capitan who held the girl he loves in his arms. 

"H-How did she get this way." He ask as he took Cass from Levi's arms. 

"They took me that she had to defend herself if not they were going to cut her up." Levi tells him bring them to Hange so she could check her out. Hange took a look at her everything was fine was just tired. 

"So are we going to put in a cell or no?" Hange asked Levi, Eren turned to them. 

"Why would she need to be there?" He held her hand tight. 

"Eren you can see she had blood on her hands right? And on her dress, it shows that she killed someone." Levi said. 

"Yeah the people who kidnapped her!" He yelled, Eren let go of Cass' hand to make a point. Armin and Misaka were there too. Watching this unfold. 

"She had to did it. How else was she going to get out." He was mad. 

"Levi one of those men was her brother, the person I sent to get her said he wanted to end a curse on their family and it had to do with the women in the family. She's the only girl left in her family." Levi tells him, but Eren didn't want to listen. 

"Eren she killed someone, get over it we now know titans use to be people, so were killing people." Misaka tell him as she holds Cass' other hand. 

"But they've ate people Cass hasn't she killed her brother for a reason. To protect herself." 

"Not really." Said a voice, everyone looked to the girl on the bed. She sat up. 

"My brother was a kind person, he liked what my dad did for people, but he said what he did was going to bring a curse on the family. I thought he died when the titans got into the walls, but I was wrong. He wanted to get rid of something that'll continue to the curse that was in my body."  Cass saids as she looked to the blood on her hands. Her brother's blood. 

"When I woke up he was there with a knife to my uterus, he said for the curse to stop he had to cut so I won't be able to continue it. Our blood line that it. Then something in my snapped, so go and put me in that jail cell, because...." Cass' eyes were unreadable. They were dark like they were when she killed her brother.
