Thanks to those who've reviewed to the previous chapters! They're all very much appreciated.

You guys will know what the Sacrifice Ending, which is an alternate ending, is later on. Anyways, I hope you guys enjoy this!

CHAPTER XI:

BACK TO THE FUTURE

Petra raced through the forest in a hurry, using her horse. Clara's reigns were in her hands. When they heard 3 gunshots and a yellow flare, Petra was worried. She didn't know if it was Cassandra or the hooded figure that sent that but she refused to lose someone she cared about once more. Finally, she found Cassandra by a tree. Ymir was tied to another one and her titan body was dissolving. She hopped off her horse and tended to Cassandra. Her temperature was dropping, her nose was bleeding and she was shivering violently.

"Cassandra? Wake up! Come on, you'll be okay!" She said but Cassandra gave no response. Petra took Cassandra's jacket off, loosened some of the belts and opened her shirt. She saw that the ice has advanced to her shoulder.

"Petra!" She heard someone call for her. Turning around, she saw Levi with the Squad and Commander Irvin and Hanji. Levi jumped off to help her up.

"Don't you dare run off like that again!" He yelled at her. Hanji and Armin helped Cassandra onto Hanji's horse while Irvin and Eren put Ymir on Clara.

"We ride back to Wall Rose." Irvin said. They all nodded and started to return to Wall Rose. When everyone has returned safe and sound to Wall Rose, despite the injuries, the Expedition was over and successful, thanks to the efforts of Cassandra Knight.

Hours later, Cassandra woke up in her bedroom, alone and tired. She tried to raise her left arm but it felt a little stiff. She brought her shirt down and saw that the ice has advanced to her shoulder. Cassandra noticed that it was already evening. She sat up, took her harnesses off and put on a decent new shirt before heading downstairs.

"I need a drink." She decided. Heading into the dining hall, she saw that no one was around. Probably sleeping off the Expedition. After drinking some water, she walked back to her room and lied on her bed for a while. Suddenly, she heard a knock on her door.

"Come in." Cassandra answered. Petra entered the room.

"How are you feeling?"

"Good. Arm's a little stiff."

Petra sat beside Cassandra and patted her leg.

"You have to seek treatment for the arm, Cassandra. At this rate, you won't be able to fight anymore." She said. Cassandra sighed.

"I know where I could possibly get treatment, Petra. But it's a long shot. If I could find an anomaly, I possibly can get treatment. And I could find Celeste for you." She answered.

"Get some rest." Petra said as she leaned in to kiss her forehead. After that, she left, leaving Cassandra alone. Once she was gone, Cassandra stood up and grabbed her things before writing a note to the Squad.

"Went on a drive. If I run into an anomaly, I'll probably go in and won't be back until a couple of days. Or weeks. Or months. Maybe even years. I don't know. It depends if I find another anomaly. See ya! :)"

Grabbing her jacket and her things, Cassandra left her room via the window by making an ice slide. According to Hanji, her car was still where they left it 3 years ago. Running towards the woods, she found her car safely hidden. Cassandra hopped on and turned the engine on. As long as there's the sun and the moon, her car was going to work. Carefully, she drove out of the place, hoping to find an anomaly. If she could, it means she can go back to her time and find out if Petra is her mother as well as get treatment. Cassandra's prayers were answered in an instant because when she made a turn there was an anomaly. It seemed weaker because it wasn't pulling her in. With resolve, she drove towards the anomaly. She went in praying that it would take her back to her time. When she got out of it, her radio, which was just giving off static earlier, started blaring music. It was daytime (1) and it was snowing. Cassandra drove back to her house and parked her car. Donning her coat and gloves, she got out of the car. There were Christmas decorations around the place. Back there, the only thing that told Cassandra that it was Christmas was the snow and it seemed a little late back there. Mustering her courage, she walked up to the door and knocked. The door was answered by her Aunt Natalie.

"Hi." She greeted. Cassandra towered over her Aunt now. Natalie touched her scarred face as if she couldn't believe that she was there.

"C-Cass?" She muttered as tears ran down her face. Natalie took Cassandra's hand and pulled her inside. Everyone was around the fireplace.

"Everyone, Cass has come home!" Natalie announced. The kids turned around and after a few seconds, ran towards her, each clinging to her legs. She noticed that the calendar said December 24.

"Cass, you're home!" Janine said joyously as they cried. Cassandra kneeled down and hugged all of them.

"I'm sorry I don't have a gift for you guys yet. I've been busy but I promise I'll make it all up for you."

"We don't care. We're just happy you're home for Christmas." Andrew said in between sobs. When they separated, Cassandra examined them as she wiped their tears away.

"You guys got big. You're 13 and 11 now, right?" She asked. The three kids nodded in reply. Rex and Duncan hugged her as well.

"Hey, boys. I hope you guys have been bringing the gold home." Cassandra teasingly said.

"Rex has. I brought a diploma home." Duncan answered as he tried not to cry. "Where were you? You disappeared for 3 years without any contact."

"I've been busy but I may have found my real mom." She answered as they stood up. Cassandra noticed that her Uncle Damon has been eyeing her warily ever since she entered.

"What are you hiding, Cass?" Uncle Damon asked her. Hesitantly, Cassandra took her jacket and gloves off. They were all shocked by how her hand has turned to ice. Damon took her hand and examined it.

"Where I've been forced me to overuse the watch to save my life. Do you have a cure for it?" Cassandra asked.

"I do. I've been improving it for the past 3 years." He answered. "I'll go get it."

"There's something else. I need your DNA tester to find out of the woman I'm friends with is my mom. Your yield immediate results." She explained as she pulled out the lock of Petra's hair from her pocket. Damon took it and a lock of Cassandra's hair before heading upstairs.

"I can't stay for long. I have to get back." She told the others. Cassandra could see the disappointment in the kids' eyes. She kneeled before them once again.

"Hey, don't look so down. I'll stay to tuck you guys in bed later, how does that sound?"

They seemed to have accepted it. Damon came down and pried the old watch off and replaced it with a new one. In an instant, the ice disappeared and turned her arm to normal. They all watched in amazement as her arm shed its ice.

"It still has the same functions that can be activated the same way. I can't fix what's wrong with your mental state but hopefully, it hasn't gotten any worse. This one's only side effect is that it very slowly deteriorates your mental state so you don't have to worry too much."

"Thank you." Cassandra said.

"Well, let's have some dinner then." Uncle Federico said. Cassandra sat there with her adoptive family for the first time in 3 years, listening to them tell stories. Thankfully, they didn't bother her about what she did. After that, the kids went to bed. As promised, Cassandra had to tuck them in. The 3 kids slept in the same room so Andrew and Andrea ran ahead while Janine was falling asleep in her arms. She put Janine in her bed while Andrew and Andrew got in theirs.

"Now if you guys are good kids, when you wake up there might be a present from Santa." She told them as she put the covers on top of them.

"When do you have to go?" Andrea asked her. Cassandra sighed before answering.

"When I get my DNA test. When did you guys find out I was adopted?"

"When you left." Andrea answered.

"Well, when you wake up I might be gone again. Good night. Merry Christmas." She greeted as she kissed their foreheads.

"Good night, Cass. Merry Christmas." They said before falling asleep. Cassandra left the room and shut the lights off.

"Cassandra." Rex greeted her.

"Yeah?"

"Uncle wanted me to give you this." He said, handing her a piece of paper. Cassandra realized that it was her DNA test. She took it and when she opened it, she nearly had a coronary upon seeing the results.

It came out positive. Petra Ral is her real mother.

AN: And that is Chapter XI! Alright, I'll explain what the number means and what the Sacrifice Ending is.

1 – Alright, when you go through the anomaly, there's a 12 hour difference between two time periods, meaning if it's night time in the past, it's day time in the future.

Sacrifice Ending – basically what you'd get if Damon didn't have a cure for Cassandra. How it'll go will be shown soon.

I hope you guys enjoyed this chapter. Thanks to those who will review!
