"You're... Mikasa and Armin." Frieda Reiss had pointed out as she stared at them.

A pair of Nineteen-year-old adults such as Mikasa Ackerman and Armin Arlert had confronted Frieda Reiss at the house where she, Adult Eren and an adolescent Ymir Fritz had stayed. The pair of Survey Corp. soldiers were begging for answers.

"You... you know us?" Armin asked.

"Um, yes. Eren told me about the both of you and-"

As Frieda was about to finish her sentence, she suddenly felt her shoulders be grabbed by the adult Mikasa Ackerman.

"Please! Tell us where Eren is!" Mikasa asked with a look of concern on her face.

"Eren? Um..." Frieda placed her right index under her chin. "If I remember correctly, he told me that he went to the interior."

"The interior, like Wall Sheenal?" Armin had asked.

"Mm-hmm." Frieda nodded.

"Where in the interior?" Mikasa asked with a gleaming look on her face as she still grabbed Frieda's shoulders. Hungry for answers.

"I-I don't know where he went inside the interior. That's all Eren had told me-that he was going to the interior and that he'll be back by tonight. Honest." Frieda said, feeling intimidated by Adult Mikasa and her gleam.

"He'll be back, tonight? What time?" Mikasa had asked.

"Wait, let her go, Mikasa." Armin had called Mikasa' name, which made her stop gleaming for a moment. "I believe she's telling the truth. Eren must've purposely not told her what he was really doing." Armin said.

"I guess you both know more about Eren's nature than I do?" Frieda asked Armin.

"He usually likes to run from us and keep his true intentions a secret." Armin told Frieda about Eren.

"Oh. He's never kept a secret from me, before." Frieda replied.

"Just who are you?" Mikasa asked Frieda.

Frieda's eyes glanced around, left and right to see a few people looking through windows and a few people standing on the street watching them. "Um... before we continue, can we talk inside? I don't want anyone to overhear us." Frieda asked, nicely.

"Sure." Armin nodded.


A Few Minutes Later...

After a few seconds had passed, Frieda had let Armin and Mikasa within the place they were currently staying.

"Okay. Now that we have privacy to ourselves, I think it is time that I introduce myself." Frieda placed her right hand on her heart. "My name Frieda. Frieda Reiss."

"Frieda Reiss?" Adult Mikasa asked.

"Mm-hmm." Frieda nodded. "I'm-"

"Hold on." Adult Armin said.

Frieda looked at Armin, whom was thinking for the moment.

Armin looked down at the floor and placed his left hand under his chin. "Reiss... Reiss... Rei-" Suddenly, Armin's eyes shot up toward Frieda. "Y-You wouldn't happen to be related to Historia, would you?" Armin asked as he looked at Frieda.

Adult Mikasa gasped.

Frieda happily smiled. "Mm-hmm. She's happily my younger sister."

Both Mikasa and Armin had gasped, surprisingly. 'Younger sister?'

"Well, now that you mention it..." As Armin had stared at Frieda, he had visualized a fifteen-year-old Historia Reiss and compared their looks. "I can definitely see the resemblance between the two of you."

"So can I." Mikasa said as she stared at Frieda.

Frieda giggled. "Eren told me that Historia within your timeline became queen." Frieda told both Mikasa and Armin.

"That's right. Historia did become queen." Armin replied.

Mikasa had suddenly paused as she had thought of what Frieda told her. "Wait... what do you mean, timeline?"

"Eh?" Frieda stared at Mikasa.

"Mikasa?" Armin asked, then looked to Frieda.

"Oh, I guess you don't know, then?" Frieda asked.

"What's going on?" Mikasa asked.

Frieda sighed, lightly. "I'll tell you everything that's happened, here."

A Few Minutes Later...

Frieda Reiss, Mikasa Ackerman and Armin Arlert had sat at a table together and it had taken Frieda had explained everything to them.

"And that is everything that I know." Frieda had told both Mikasa and Armin.

Both Mikasa and Armin had visible shocked looks on their faces and they both were surprised of what Eren did.

"Wow. I never thought Eren would do such a thing." Mikasa said as she grasped her right head.

"Using the Founding Titan's power to travel all the way back to when Wall Maria fell-just to save everyone within the walls." Armin blinked, once. "It's... it's..." Armin begun to hesitate to finish his sentence.

"Hm?" Frieda stared at Armin for a moment as he hesitated.

"It's genius!" Armin yelled. "Eren really was on our side, after all!"

"Eh?" Frieda felt a bit thrown off by Armin's reaction.

"What do you mean, Armin?" Mikasa asked.

"Don't you get it, Mikasa? Eren used the Founder's power to create a whole another timeline! That means everyone who originally died when Wall Maria fell is still alive! Doctor Yeager. Misses Yeager. My grandfather!" Armin told Mikasa.

Mikasa gasped. "But, how did Eren even-"

"I don't know how Eren came up with the ability to time travel, but I'm sure that Eren did it thinking about the safety of everyone on Paradis within our own timeline."

"What made you think that?" Frieda asked.

"When Eren begun working with Zeke and the Yeagerists, Mikasa and I had assumed that Eren was under Zeke's influence and that he was trying to help him start the Eldian Euthanization plan. But the moment when Eren had disappeared right in front of our very eyes..."

Mikasa frowned. She knew where Armin was going with the conversation.

Brief Flashback

For six seconds, Eren Yeager's severed head had flown in midair toward Zeke for six seconds, until his head was caught by Zeke Yeager's right hand. And the moment when Zeke Yeager made contact with Eren's head, something mysterious had happened.

A long blue spinal-like creature had quickly emerged from Eren Yeager's body and had attached to Eren's severed head. The moment it had... Eren's eyes and mouth begun to glow a shining bright color. Within the next ten seconds, a lightning bolt had struck Eren's body. Causing Eren Yeager, himself, to vanish from thin air. Leaving nothing left of Eren.

End Brief Flashback

"I knew that Eren had somewhat rebelled against Zeke. And to be honest, when a lightning bolt had struck him... part of me thought that Eren was gone-like, gone from the world of the living." Armin told Frieda.

"I understand." Frieda replied.

Suddenly, a gasp was heard coming from behind Frieda.

All three, such as Mikasa Ackerman, Frieda Reiss and Armin Arlert look at Mikasa, whom was looking and staring in the direction of two o'clock. Then, they followed Mikasa's eyes and looked in the direction that Mikasa was looking. They had spotted the young and adolescent Ymir. Standing on the steps and just staring at them from a few yards from where they were sitting.

'A child?' Armin had thought.

"Ymir?" Frieda had called as she had slowly risen up from the table and begun walking toward the.

Mikasa gasped.

"That can't be right..." Armin said, then thought of the tall and dark-haired Ymir she had known within his timeline.

"The Ymir we knew was taller." Mikasa said as she had visualized the tall Ymir that they had known.

Frieda giggled. "She's a different Ymir."

"How so?" Mikasa asked.

Frieda then removed herself from the table and walked toward Ymir. She gently grabbed placed her hands on Ymir's shoulders. "This Ymir was born thousands of years before any of us. And, um..." Frieda had stopped herself for a moment. Trying to find a way to explain Ymir's story to both Mikasa and Armin, normally. "She was the first ever Titan to exist."

Both Mikasa and Armin had quickly gasped in shock.

Armin gasped and jumped from his chair. "Wait, SHE's the progenitor?"

"The first ever Titan?" Mikasa asked as she jumped from her chair.

"That's right." Frieda had nodded, normally.

"Wow. I never imagined that the progenitor of all Titans would actually be a child. It's kind of bizarre." Armin said as he normally stared at the young Ymir.

Frieda had frowned as she thought of Ymir's history. "She's had a hard and terrible life. Eren told what Ymir had gone through, before and after she had obtained Titan powers. It's cruel." Frieda glanced downward at the floor with her sky-blue eyes.

Both Mikasa and Armin had stared at Frieda had frowned and had sadness in her sky-blue eyes. They've seen those kinds of eyes many times.

"We completely understand." Armin said.

Frieda looked up at both Mikasa and Armin. "This Ymir, here isn't originally from this timeline. Just as my-I mean, "your" Eren isn't from this timeline, either. A little while ago, Eren and I had traveled to another timeline in order to rescue her from her cruel fate." Frieda had explained.

Both Mikasa and Armin had gasped, surprisingly.

"So, you and Eren can use the Founder to travel through time?" Armin had asked.

"Too be honest, I had no idea that ability existed at all, until the night that Eren had saved me." Frieda said.

"Save you? From what?" Mikasa asked.

"The King's vow. I was placed inside of a mental prison as when I first possessed the Founding Titan. I couldn't break free from the vow on my own. Whenever I try to act on my own free will, I would easily get possessed by King Karl Fritz's vow."

Armin had gasped. "So, it's true. Every royal Reiss member who possesses the Founder gets taken over by the vow, instantly. Making them slaves in the mind."

"Mm-hmm." Frieda nodded. "I'm free, now. Thanks to Eren."

Mikasa gasped. "Eren freed you? How?"

Frieda nodded, once more. "On the night before the Warrior Unit were supposed to breach Wall Maria... Eren from your timeline had appeared before my family. He found my family's chapel and tried to convince me to save everyone in this timeline." Frieda had remembered when she met Adult Eren inside the underground catacombs.

"Did you agree to help him?" Mikasa asked.

"At first, I didn't. Even though, I wanted to." Frieda shook her head no. "King Karl Fritz had possessed my mind, rendering me from aiding Eren.

"You should've fought harder and helped him." Mikasa said in a bit of frustration.

Frieda gasped.

"Mikasa, please. Even if she wanted to help, there was no way that she could fend off against King Karl Fritz's overwhelming power." Armin said raising his left hand toward Mikasa.

"Tch." Mikasa looked away turning her head in another direction.

Armin then looked to Frieda. "I'm sorry for what you had to go through, Frieda. But, I'm sure that you would've wanted to help Eren and all of those in need." Armin said with a comforting smile.

"You're right. I could've saved a number of people already, if not for the Vow of Pacifism. Anyway, Eren had found me and he saved me from the vow-allowing me to think and act on my own." Frieda had stated.

Brief Flashback

Frieda Reiss heard all of her family's pleas and encouragement to not listen to and get rid of Eren Yeager. She sighed and turned towards Eren to give him her final verdict. "I'm sorry, Eren, but I-Mmph!" Before Frieda could finish saying what she had to say, she was quickly shushed by a Nineteen-year-old Eren Yeager, as he pressed his lips against Frieda's, kissing her. Frieda's eyes opened in shock, as he felt his tongue roaming her throat.

Suddenly, sparks of electricity start zapping around the two, as Eren, a holder of the Founding Titan had made contact with a member of the Royal Family. Both Eren and Frieda possessed the Power of the Founding Titan. Frieda's eyes began to glow, as the "Vow of Pacifism" attempt to take over her mind.

End Brief Flashback

"If not for him intervening, then the walls would've been breached, and I would've been eaten by Doctor Yeager." Frieda stated.

Both Mikasa and Armin gasped when they heard, "Doctor Yeager."

"Doctor Yeager? He's alive?" Mikasa asked.

"Mm-hmm." Frieda nodded, once again. "After we rescued Ymir from her timeline, we instantly went to Doctor Yeager's house-and Ymir, here had removed the curse from Doctor Yeager's body. Making him a normal person, again."

Armin and Mikasa had gasped, once again. But not in shock, but in amazement. They had no idea that could happen.

"That girl can remove Titan curses?" Mikasa asked and pointed at the young Ymir.

"That's right. But, I want to keep Ymir's existence a secret for now-so that no one can use her. Especially, from the military. Eren had told me how the Military treated him, when he joined the Survey Corps." Frieda said.

Both Mikasa and Armin had then thought of one certain incident when Eren Yeager had been brutally beaten by Levi Ackerman within a courthouse in the year, Eight Fifty.

"We understand. Wouldn't want anything bad to happen to neither you or little Ymir." Armin said as he kneeled before Ymir.

Knock Knock

The four Eldians had turned to the front door after hearing the knock.

"Someone's here?" Mikasa asked as she had turned seventy-five percent of her body toward the front door.

"I wonder, who could that be?" Armin asked, quietly.

Frieda Reiss's eyes had narrowed as she glanced at the door.

There had been utter silence for half a minute. Everyone in the house continued staring, until they all heard a voice.

"Is everything okay, Frieda?"

Frieda Reiss, Mikasa Ackerman and Armin Arlert silently gasped as their eyes widened. They recognized that voice.

'That voice!' Mikasa had thought.

'It really is...' Armin had thought.

Adult Eren Yeager had stood outside of the house and on the other side of the front door. He stood still, like a statue. "I know that I came a little sooner, than planned, but..." Eren said as had held the hand of an adolescent girl standing next to him. Her name was Historia Reiss. Who seemed happy.
