"It's a castle!" Ava exclaimed. A an old story of a castle and a fallen squad entered her mind "Wait." She looked up at her two fathers and opened her mouth to ask a question, but her brother beat her to it.

"Is this the place that was your first HQ?" Gabriel asked, surveying the castle.

"Yup," Eren said, a smile on his face. A smile that held a hint of sadness.

"Go explore," Levi said. The twins took off running. Eren and Levi had placed everything for their birthday in a room and locked it. So they wouldn't find anything in their adventure through the castle.

Levi and Eren walked around, taking their time. They walked through the halls of the castle, truly reminiscing, eventually making their way outside, found their kids. They were standing quietly in front of four crosses that Levi and Eren had made many years ago.

"Who are they?" Ava asked quietly.

"My first squad," Levi answered.

"You never said what happened, or their names," Gabriel said. Eren walked forward."You only said that they died."

"Petra, Gunter, Erd, and Auruo," Eren said, pointing to each one. "They gave their lives trying to save me." Eren hung his head, remembering that day. He remembered the pain of having to let them give their lives as he fled. The agony as he heard them die, one by one, by a person he thought was a comrade. He remembered the stench of their blood that filled the air. And most importantly, he remembered the guilt of letting them take his place in the ground.

"Go explore inside," Levi said, he face downcast. The twins nodded and left, not wanting to bring any more painful memories. They saw the sad look that both of their fathers had. Levi walked toward Eren and pulled him into a long embrace, cradling Eren's head to his chest.

"What do you think they would say about us?" Eren asked after a moment. "You know, about being a couple?"

"They would have been with Erwin and Hanji making bets," Levi said without hesitation. Eren nodded, knowing it was most likely true. Petra, being the kind soul she was, would probably have given Eren dating advice. Aurou would have bitten his tongue with any comment he would have tried to said. Erd and Gunter would have been the two that went around creating betting pools and watched silently from the sidelines. Eren didn't realize how much he missed them until he truly thought about them. And he knew that of he missed them, Levi would as well. Levi knew them longer and was more attached to them. "Let's go spend some time with our kids." Eren nodded and together they walked inside.

Eren was the one to prepare dinner, and once he was done, he went to go get his family. He found Levi and Gabriel already at the table, engrossed in a conversation. He smiled and leaned against the door frame and watched his love and child talk about anything and everything. It was the first time in a while that those two had actually sat down and talked about nothing in particular.

"Where's Ava?" Eren asked after a few moments. He walked over and slung his arms around Levi's shoulders and kissed his cheek.

"Outside," Levi said, grabbing onto one of Eren's hands.

"Okay," Eren said, with a squeeze to Levi's hands he stood up and brought his arms back to his sides. "I'll go get her. Go wash up an get ready for dinner." He went outside an walked around the castle looking for his daughter, wondering where she could be. He walked around a corner and found her kneeling in front of the crosses.

"So, anyways I just wanted to say thank you, for saving my dad," Eren heard Ava say. "My other dad wouldn't be the way he is if you hadn't. And Gabriel and I wouldn't have him. So, because of you four, my parents were able to start a life together and become happy. They are where they are now because of your sacrifices. I wish I could thank you in person, but this is the best I can do. I'm sad I couldn't meet you guys. I don't know if you guys can hear me, but I like to think that you can. And that you are still watching over my parents. You are truly their guardian angels. Thank you so much for the opportunity you gave them for a happy life, even though it meant that you didn't get one." Ava sat there for a second and Eren walked up behind her.

"Hey, it's time for dinner," Eren said, putting a hand on her shoulder. Ava stood up quickly.

"How long have you been there?" Ava asked surprised.

"Just now," Eren said, pretending that he didn't hear anything. Ava nodded her head, tears glinting in the sunlight. Eren gave her a gentle smile and reached up and wiped the tears away. He gave her a moment before walking back inside to the table together.

Later, when everyone was in their respectful rooms, Eren rolled over in his bed and looked at Levi.

"When I found Ava, she was in front of the crosses," Eren said.

"Really?" Levi asked. Eren nodded. He told Levi what he heard. "She's right though. If I didn't have you, I would be completely different. And vice versa. But what she said, it was so sweet. She was talking as if they were right in front of her. But she said something that i like to believe too."

"What would that be?" Levi asked, pulling Eren into his arms.

"She said that she likes to think that they could hear her," Eren said. "And I hope so too, because I know they would have liked what she said. They would have liked her."

"Yeah, they would have," Levi mumbled, eyes closed and half asleep. Eren leaned up and kissed the side of Levi's mouth before settling back down and closing his eyes.

Eren and Levi woke up when the first beams of sunlight slid into their room. They got dressed and brought everything out of the locked room and set it up. They hung a banner that they made personally, and, made and decorated the cake. They also quickly set up the other few small decorations that they had.

"Now it's just left to wake them up in the order they were born," Eren said, rubbing his hands together.

"Only one problem with that," Levi said. "Hanji never told anyone the order they were born. So we don't know."

"Then we choose," Eren said, shrugging his shoulders. They looked at each other for a moment and silently agreed. They walked towards one of the rooms. They opened the door quietly and went to the foot of the bed. Eren turned and looked at Levi. He held up three fingers and Levi nodded, agreeing with the plan that was actually never discussed. He started counting down. When the last finger was down they pounced.

"Happy birthday!" Eren and Levi shouted as they landed on the bed. Eren's voice slightly louder and more energetic. They wrapped their arms around their sleeping kid and hugged as tight as they could.

"You're gonna kill me," Gabriel wheezed. Eren let go an sat up. Levi did the same and looked at Gabriel. He was glaring at the two grown and married men, his hair sticking every which way.

"Now we need to wake up your sister and then we will tell you the plans for today," Eren said. Eren and Levi jumped off the bed and ran down the hallway. They did the exact same thing with Ava.

When both kids were out they looked around at what their fathers had set up. Their faces hald looks of equal parts awe and happiness.

"Dad, Vatti," Gabriel said. "This was more than I could have hoped for. More than I had imagined."

"Same here," Ava said, still looking around, smiling from ear to ear.

Eren and Levi explained what they were going to do that day. Ava and Gabriel were excited at the plans.

They had a big breakfast that both Eren and Levi made together with the kids watching, like when they were little. They did some stunts with their 3DMG. Each one of them showing off their skills, with obviously Levi being the flashiest of them all. They did many activities that the twins enjoyed. After dinner, that Levi and Eren cooked, they had cake.

"Can we ask you two a question?" Eren asked.

"Of course, Vatti," Ava said.

"How come you never asked about your birth parents?" Levi asked. Ava and Gabriel looked at each other.

"Because it's not important to us," Ava said. "I know that sounds cruel, but it's the truth. You're the ones that are important to us."

"We have you two," Gabriel said. "To us, that's better than having a biological parent."

"Yeah," Ava agreed. "To us, you are our parents. It doesn't matter that we don't have your blood running though our veins. You raised us. Cared for us. Taught us everything we know. And that's all we could ever hope for. And to us, that truly what a parent is. Not blood." Eren smiled. Levi reached over and grabbed Eren's hand, giving it a slight squeeze.

They returned to the current headquarters around noon the next day. All of them looking more refreshed than before they left. They all needed that small get away with each other. It was long overdue.

"How your birthday?" Mikasa asked after everyone had settled down.

"Wonderful," Ava said.

"Vatti and Dad really out did themselves," Gabriel said. "It was the best."

"Good," Mikasa said. "Well, since you weren't here yesterday, we are going to celebrate with you today." The twins smiled.

A month passed quickly with everything being normal. There was a short mission beyond the walls, but it was nothing more than a recon mission. Levi and Eren's squad got back home unharmed. Most squads remained intact.

Eren woke up before Levi and after a moment on pondering how Levi would react, he pounced on him.

"What the fuck do you think you are doing, Shitty Brat?" Levi asked with his eyes still closed. Eren laid on top of Levi and kissed his neck. Levi wrapped his arms around Eren, and kissed him. He didn't know the cause of this morning wake up, but he liked it. Well, besides getting pounced on.

"Do you know what day it is tomorrow is?" Eren asked excitedly.

"You're like a little kid," Levi said. "But what is tomorrow?" Eren pouted and Levi kissed him.

"You really don't know?" Eren asked, still pouting.

"I love it when you do that," Levi said, pulling Eren into another kiss. "I do know what tomorrow is. Of course I know. How could I forget?"

"It's our sixteenth anniversary!" Eren almost shouted.

"Quiet," Levi said. "Do you want to wake everyone up?" Levi smiled his real smile and Eren's face lit up. He leaned down and kissed Levi again.

"So what shall we do?" Eren asked.

"In thinking that we can do what we did with the twins," Levi said. "Just you and I. Alone in the castle. Celebrating the day we married."

"I like that," Eren said. Levi kissed Eren again and they got up. They went out to everyone and told them of their plan. Everyone fully supported their plan. Mikasa took responsibility for the twins and Marcus. Which, after last time Levi and Eren left, Marcus quickly learned not to disobey Mikasa. After lunch they left, remembering to pack lunch for the second time in a row.

The next day Eren an Levi laid in bed almost all on of them wanting to leave the other, let alone put clothes on. There was hardly a moment when they were a part.

"Eren Ackerman," Levi said.

"Yes?" Eren hummed.

"The day you went from Eren Jaeger to Ackerman, was a day I will never forget," Levi said. "It will always be the second most happiest day of my life."

"What was the first?" Eren asked sitting up, a confused look on his face.

"They day I woke up and found that you were normal," Levi said. "The day we got together." Eren kissed Levi's neck.

"That was a good day," Eren said. "Wasn't it, Daddy?" The slight smile fell from Levi's lips. Eren laughed when his teasing worked.

"No more sex today for you," Levi said.

"Oh come on Daddy, don't be that way," Eren laughed.

"You are sick and twisted," Levi said, pushing Eren towards the other side of the bed. Eren laughed harder, clutching at his sides.

"Levi Ackerman," Eren said. "You make it too easy to mess with you." Levi glared at Eren.

"Don't do twisted shit," levi said. Eren crawled back over and kissed Levi's neck.

"I'll make it up to you," Eren said in a sultry tone. .

"No," Levi said darkly. "I'm going to make you pay." Eren's eyes widened, a flash of fear running through his eyes.

"Oh shit," Eren said, knowing he was fucked, figuratively and literally. Levi got a deadly look in his eyes and slightly smiled.

They returned late the next day, wanting to take their time on the ride back. Hanji was already asking them questions the moment they walked through the door. Levi and Eren ignored every last one of them, not going to give her the pleasure of the answers that she wanted.

Everyone sat around the table with the conversation turning normal. People were laughing and talking. Eren looked around. He had a husband of sixteen years, and two kids. He was surrounded by friends that would give their life for each other. He knew, that this was the moment to live for. This was the moment that he wouldn't trade for anything. Ava and Gabriel looked over at Eren and they both smiled. Eren smiled back brightly at them. Eren then felt a finger on his face, turning it. He turned and looked at Levi, who still had his hand on Eren's face.

Levi leaned in a kissed Eren, not holding anything back in front of the entire squad. And Eren knew, that even with everything that happened to him, he wouldn't change a thing. This was the life he wanted.

A/N: Before I say anything, can I point out how much I love that this just happened to be 30 chapters exactly? That was a complete and utter accident.

Anyways, real talk. This was the last and final chapter of Rewind. I am so happy that you guys are here and reading this message. Because that means that you have stuck with me throughout the story.
