Within Grisha's Basement...

Within Grisha Yeager's basement... Adult Eren Yeager, Frieda Reiss and a young Ymir Fritz were standing in Grisha's basement, once more. Grisha was sitting at his desk and clasping his fingers, together.

"Eren, tell me. What has come of Paradis within your timeline?" Grisha had asked his adult son.

"Well, to be honest, dad. After Marley attacked, I fear that the chances of Paradis' survival within my timeline are slim to none. The island is doomed to be destroyed by the entire world, unless I try and come up with a solution to save everyone over there." Eren had told Grisha.

"I see... well it seems that the Mikasa and Armin we saw through that strange phenomenon have fully grown up and are in great health. Which means, that the entire world had not attacked the Paradis in your original timeline, yet." Grisha assumed as he remembered seeing both Mikasa and Armin as fully grown adults.

"Yes. The Mikasa and Armin over there are okay for now. But I don't know how much time they or Paradis over there as a whole has left, though." Eren said.

"Eren?" Frieda muttered.

"Moments before I attacked Marley in own my timeline... Willy of the Tybur Family had already convinced the entire world government to war against Paradis. He did it, because he and billions of people around the world were afraid of the potential Rumbling. I don't know how but somehow; he knew that the Founder's power wasn't in the hands of the royal family." Eren stated.

"So, you're telling me that you had no choice but to attack Marley?" Grisha asked.

"I wouldn't say that, exactly. But on that night when I attacked Marley, Armin had destroyed the Marleyean fleet and I stole the Warhammer Titan from the Tybur Family because I thought that it would be useful-in case Marley, or any other nation attacked." Eren rubbed his left ear. "And to some degree, I was right." Eren then briefly thought of the time when he fought Lara Tybur and crushed her inside a crystal while using the Jaw Titan's jaw as a nutcracker. "And even if I didn't attack Marley on that night, the entire world would've still agreed to attack Paradis regardless out of fear for the Rumbling." Eren had stated.

"Eren." Grisha suddenly rose from his desk and approached his adult son and grasped his shoulders. They made eye contact with each other. "I understand that you've went through a great deal to get this far-and that the entire world choosing to war against Paradis in your timeline was out of your reach and that you felt you had to carry this huge burden... But whatever you do. Please. Promise me that the Paradis in this timeline won't suffer the same fate as the other one." Grisha asked as he gripped Eren's shoulders.

"I will." Eren had nodded.

Ymir Fritz and Frieda simply watched the entire father and son conversation with worry.


A Few Moments Later...

"Goodbye, Miss Carla!" Frieda smiled as she kindly waved to Carla Yeager.

Carla was currently cutting bread with a knife at a counter, in front of a window, until she heard her name called by Frieda. She turned to see Frieda Reiss, an adolescent Ymir Fritz and an adult Eren Yeager, whom she has no idea is her adult son. They were standing in front of the front door, ready to exit the Yeager's home. "Oh? You're all leaving, already?" Carla had asked.

"Mm-hmm." Frieda nodded. "We're going to, um..." Frieda had choked for a second as she did not know what to do, next. Eren then whispered in Frieda's left ear. "What's that?" Frieda temporarily glanced at Eren as she heard words coming from Eren's mouth. Eren then whispered in her ear, once more. "T-that's right!" Frieda gasped.

"We're going to find jobs here in Shiganshina." Frieda smiled.

"Oh? What kind of job?" Carla had asked.

"Any kind of job that helps put a roof over our heads." Frieda had replied.

"That's sounds nice. You two are working, but what about her?" Carla then looked down at Ymir. "Someone has to look after this little one, while you two are gone." Carla said as she looked at the adolescent Ymir Fritz.

"I'm good at babysitting. I'll be a full-time babysitter. And little Ymir can stay with me while I babysit other people's children." Frieda smiled as she told Carla.

Carla chuckled and placed her left hand on her left cheek. "I have never met anyone who wants to be a full-time babysitter... but if it can pay bills, then I am okay with it." Frieda then turned her attention to her adult son. "And what about you, Kruger? What kind of job are you going to get?"

"Mmph," Adult Eren had muffled. 'What kind of job I'm going to get?' He had thought for a moment, then he remembered Carla's reaction to Eren wanting to join the Survey Corp. 'That's right. I can't tell her that I want to join the Survey Corp. Knowing mom, she'd probably try to talk me out of it.' Eren had thought, then opened his mouth, slowly. "I..."

"Hm?"

"I'm thinking about starting a company-like that Dimo Reeves guy who lives in Wall Rose." Eren had told Carla.

"Dimo Reeves... Starting a company..." Carla had thought as she had placed her left index finger on her chin and looked up to the ceiling. "Oh! You mean, you'll be a merchant?" Carla asked.

"Yes. I want to make lots of money." Eren quickly nodded.

"I guess that's an honest living for you."

"And when I become rich, I can help both you and Doctor Yeager, financially." Eren had added. "You don't ever have to worry about getting by, ever again."

"Eh?" Carla had stood still for a moment, then she suddenly begun to laugh. "I appreciate you trying to look after me and my family, Kruger. But you don't have to worry about us, financially."

"Hm?"

"My husband is a famous doctor who travels and makes lots of money-especially in the interior." Carla stated.

"Right." Eren said.

"And also... having lots of money doesn't make a person truly happy. Having family that support you does." Carla had told Eren.

Frieda then had thought of her younger sister, Historia.

"I'll remember that. Thanks." Eren said. 'Mom.'


A Few Moments Later...

Shortly, the three Titans Shifters such as Adult Eren Yeager, Frieda Reiss and a young Ymir Fritz had departed from Eren's old home and were walking down the street with a few dozen people roaming as well. They were roaming toward the house they settled down in a house far northwest from Eren's old home in Shiganshina. The sun was shining and some birds were chirping. Adult Eren and Frieda were holding hands like a couple and the young Ymir was walking in front as if she was their child.

"Hey, Eren." Frieda had called as she walked beside him. As soon as she got his attention. "Now that the everyone here in Shiganshina are now safe from the Warriors and that Ymir had cured Doctor Yeager from the curse... what do you propose we should do, next?" Frieda quietly asked, curiously.

Eren had thought for a moment. "Hmm... well, to be honest, I don't know where to start. There are lots of different options we can pick from."

"Eren?"

"Since we the walls are saved and that we now have some time to spare, we can either..." Eren raised his right index finger. "One. We could stay in this timeline and reveal the truth of the world to everyone on this island." Eren had raised his right middle finger. "Two. We could go to my original timeline and try to save everyone there. Or the third option." Eren then raised his right ring finger. "We could go back to Ymir's timeline and free her people. I say "her people" because Ymir and everyone in her village was captured by the King of Eldians at that time, before she made contact with the Source of all Living Matter." Eren had stated.

The young adolescent Ymir Fritz glanced at Eren while walking when he mentioned her timeline.

"I see. That really sounds like a lot to do." Frieda said as she listened to Eren's three options. "But, what would we do, once we free little Ymir's people?"

"We can stop the King at that time and bring Ymir's people here to this timeline and have dad treat each and every one of them. But sadly, they can't grow their tongues back-since they're not Ymir's descendants." Eren stated.

Frieda silently gasped as she had forgotten about Ymir and her fellow villagers were enslaved by the king of Eldians during that time.

"They can't go back to the lives they once lived, but at the very least they can start a new one, here." Eren said as he thought of Ymir's people.

"That sounds like a good idea. Relocating people from one place to another." Frieda smiled as she liked the idea. "But, what about over there with... you know." Frieda had begun to hint about Eren's old timeline.

Eren had taken a deep breath, shortly after he knew what Frieda was trying to get at. "I know what you're trying to say, but I'm worried about them over there, too. But until we can think of a plan to try and save Mikasa and Armin and everyone else over there there's nothing we can really do, yet." Eren had said.

Unbeknownst to Adult Eren, Frieda and the adolescent Ymir... there were two kids walking passing by as they were running straight home. These two kids were adolescent Eren Yeager and an adolescent Mikasa Ackerman. The Adolescent Mikasa Ackerman was running a yard and a half behind the younger Eren.

As she ran, Mikasa had automatically gasped when she heard her name and Armin's called by the Eren's older counterpart. She stopped running and turned her back toward the younger Eren. She looked at the backsides of Adult Eren, Frieda and the adolescent Ymir Fritz as they were walking further away. 'That's weird. I thought I heard someone call my name out loud.' She thought as she kept looking at their backsides from afar.

"Hey, Mikasa!"

The young Mikasa had gasped when the younger Eren had called her name.

"What are you staring at? C'mon!" The younger Eren had called Mikasa over to come and follow him.

The younger Mikasa had quickly turned back to the younger Eren. "R-right! Coming!" The young girl had continued running behind Eren.


Later That Night...

The night young and dozens of the stars within the sky shined. Ymir Fritz was resting in an individual child-sized bed, sleeping soundly in an individual room. In another room within the two-storied house... Frieda Reiss was dressed in her white gown. She was dressed in her white pajama shirt, pair of pink shorts. She currently sat in front of a mirror and brushed her front bangs. Her black her was tied in a bun.

"Hey, Frieda." Eren had called, whom had walked in the bedroom.

"What is it, Eren?" Frieda had replied.

"I came to tell you that Ymir is soundly asleep." Eren told Frieda as he looked at Frieda's reflection through the mirror.

"That's nice." Frieda smiled.

"And also... I'm going somewhere, tonight." Eren had added.

"Huh? Where are you going?" Frieda asked, curiously.

"I'm going to the interior within a few minutes." Eren had said.

Frieda gasped, then turned around. "I-Is there something wrong?"

"No." Eren shook his head no. "But I must take care of personal business, as soon as possible. Because if I don't do it right away, then I'm afraid that I'm going to regret it, later on." Eren said.

"Oh..." Frieda replied, then she had removed herself from her desk and stood. She slowly walked toward her lover, Adult Eren and the couple made eye contact with one another. She then stroked Eren's right cheek with her left hand. "Promise me that you won't do anything crazy."

"I won't." Eren said as he gently grabbed Frieda's left hand and removed it from his left cheek. "And as soon as I finish taking care of what I need, I will be right back to protect you. I swear."

"Okay." Frieda said, softly.

"Hm," Adult Eren smiled. And without a second's hesitation, he leaned his head forward and kissed Frieda on her lips. Frieda shortly kissed him back, romantically. Their kiss only lasted for thirteen seconds. "I'll try to be back within twenty-four hours."

"I believe you." Frieda nodded.

Eren wrapped his arms around Frieda, embracing her. "Make sure all of the doors are locked."

"I will." Frieda replied as she hugged him back.


The Next Morning...

Eren Yeager had departed from their home the previous night to take care of business within the interior. A rooster standing on top of a roof of a house within the northwest area of Shiganshina District. It had crowed as soon as the sun had risen up in the sky.

Frieda Reiss was currently sleeping in her bed. She had woken up as soon as the rooster had crowed. She had stayed in bed for another two minutes until she heard knocks on her front door coming from downstairs. She silently gasped. The knocks she heard weren't rough or violent bangs. They were rather almost soft. 'Those knocks. They don't sound like Eren's knockings.' Frieda had thought.

"Frieda?" The young Ymir Fritz had approached Frieda as she stood by her bedroom doorframe.

"It's okay. I'll go check who it is." Frieda smiled, assuring Ymir that everything was alright. Frieda then walked downstairs, leaving the young Ymir Fritz to stare at her, a bit worried.

Frieda Reiss then approached the front door within the two-story house. She heard a few more knocks from the door as she stood in front of it. After standing for another ten seconds, she took a deep breath and grabbed the doorknob. Then, twisted it so the door could open. But as soon as Frieda had opened the door... "You're back already, Eren? It's kind of too soon for-" Frieda suddenly stopped talking and stared.

"Y... you know Eren?" A masculine voice asked.

"Um... yes." Frieda nodded, then gasped. "Wait, you two are..." Frieda Reiss was seen staring at the adult counterparts of Mikasa Ackerman and Armin Arlert. They looked at her in shock and in concern. They were standing in front of the house that the Adult Eren, Frieda and the young Ymir were staying.

"C-Can you tell us where Eren is? Please, we need your help." Armin begged Frieda.

Mikasa had a look of concern on her face.
