Ten minutes after Historia and Frieda Reiss had reunited on the farm after so long... Eren and Ymir decided to approach them.
"Is everyone having fun?" Eren asked the Reiss sisters.
As Historia kept hugging Frieda for ten minutes straight, she heard a masculine voice and looked to see her comrade in arms, Eren. She then gasped. "Eren?"
"Hey, Historia." Eren waved to Historia. "It's been a while."
"Eren... was it you... who... brought Frieda back to me?" Historia asked.
Eren had nodded.
"But, how?" Historia asked, seeming confused.
"He saved me from my demise. He traveled to my timeline and freed me from the King's vow. After that, we managed to save lots of people in Wall Maria from the Warrior Unit."
Historia looked at Frieda in shock. "T-Timeline?" Historia then looked to Eren.
"I used the Founder's power to travel to another point in time and saved Frieda and everyone in Wall Maria from their demise. But, I couldn't save everyone." Eren had informed Historia.
"You... really used the Founder's power to do that?" Historia asked Eren.
"Yeah. I did." Eren nodded.
"I... didn't even know the Founder could do that."
"It was a last-minute discovery." Eren said to historia.
As Historia gasped and had stared at Eren, she couldn't help but think of the last time they had spoken in general.
Flashback
One day on the farm, Historia and Eren had talked. Eren had shorter hair, which was neck-length. They stood in front of the fence and watched the sun set.
"I'm going to use the Founder's power to start the Rumbling and trample all over the world outside Paradis." Eren had told Historia.
Historia fully faced Eren with shock, worry and sadness. "That isn't the answer, Eren! I understand that people from outside Paradis hate Eldians, but there are still billions of innocent people still out there! If you do that, then they'll only die ignorant deaths, just like your mom! Is that what you really want?" Historia asked.
"I know, it's horrible. You're right. But when I begin the Rumbling and finish it, I'm going finally to break the cycle of hatred that Eldians had been trapped in for the past two thousand years. And then, Eldians within Paradis will be able to live freely." Eren had told Historia.
End Flashback
"You've changed, Eren." Historia said as she made eye contact.
"I have." Eren nodded. "I knew how much you loved Frieda-and how much you cared about the innocent lives outside Paradis. I had to think of another solution to try and save Paradis-instead of resulting in using the Rumbling. Even if it means, traveling to a different time period." Eren told Historia as he looked at her hands.
Historia gained a bright and honest smile on her face. "Thank you, Eren. For thinking about my feelings." Historia's eyes watered in joy. "If you hadn't, then I would have never had gotten the chance to thank Frieda." Historia said as she wiped the orbs of water from her eyes.
"Anything for the worst girl in the world." Eren said.
Historia chuckled, then suddenly noticed Ymir standing behind Eren. "Ymir?"
"Uh, hi?" Ymir waved toward the young adult Historia. Clearly not knowing her at all.
"This Ymir came from the same timeline as Frieda did." Eren had informed Historia.
Historia looked at Eren and gasped, temporarily. "Really?"
Ymir sighed as she faced Historia. "Listen, shorty. I don't know anything about my future predecessor, nor do I care to know what kind of relationship she had with you. I'm a totally different person. I'm not just gonna fall head over heels for some blonde-haired, blue-eyed Loli without knowing who you are, first." Ymir said as she pointed her right thumb at her chest.
"Y-Ymir! That's rude!" Frieda called.
"What? I'm just simply telling her honest truth, here." Ymir replied to Frieda while shrugging.
"I know, but do you act so blunt?" Frieda asked as she argued with Ymir.
As Frieda and Ymir were arguing back and forth, Historia smiled as she listened to Ymir's voice. 'You haven't changed a bit. You're just as brutally honest as the Ymir I knew.' Historia's mind suddenly traveled down memory lane as she had remembered the time when Ymir had attempted to convince Sasha to use her real accent and live for herself. Suddenly, Historia laughs, which breaks up the argument between Frieda Reiss and Ymir. "I'm happy to see your face again. Even though you're not "my" Ymir."
"Uh, thanks?" Ymir rubbed the back of her neck with her right hand.
"Heh." Historia chuckled, once more. "You know, the Ymir that once I knew was obsessed with wanting to marry me."
"Oh? Well, then she must've sounded like the luckiest girl in the world." Ymir said, referring to her future and deceased counterpart.
Historia looked down and frowned, then remembered the last time that she and Ymir had last spoken. "She was."
Frieda smiled at the sound of Historia chuckling. "Oh! There's something that I almost forgot to tell you."
"Hm?" Historia then looked up to Frieda.
"This Eren and I are engaged to be married." Frieda had pointed toward her fiancé, Eren.
Historia suddenly gasped, feeling surprised. "What?" Her cheeks suddenly turned into red spots. She then looked at Eren. "Eren! Y-you're marrying my sister?"
"I am." Eren replied.
"B-but you just reunited us both! It's too soon for you both to marry!" Historia then turned to Frieda. "Frieda, please tell him that!" Historia begged.
"Well, I mean... Eren did save me, and he has a really attractive..." Frieda blushed as she looked down at the corner of her left vision.
"Huh?" Historia gasped and blushed.
"I know it's too soon for that, but when the time comes, Frieda and I will one day get married." Eren said as he smiled lightly to Frieda.
"Mm-hmm." Frieda smiled while blushing.
"She's the only one for me." Eren told Historia.
Historia gasped again, with her mouth halfway hanging. "Wow. I never thought I'd hear you say that. And I thought you would've asked out Mikasa at this point." Historia said.
"I honestly don't deserve her." Eren quickly replied, then thought of the last time he saw her in the flesh. "Especially after..." Eren had hesitated to utter another word as he visualized her crying.
"After what?" Historia asked.
"After... I had-"
Frieda suddenly placed her hands on Historia's shoulders while standing behind her. "Well, Historia. Eren had a big fight with both Mikasa and Armin and now he's going to find them and apologize. Right, Eren?" Frieda asked as she then stared at Eren.
"Yes. I said some things that I regret saying to them. And now I want to make up for all my wrongdoings." Eren said as he had thought of the last time, he had spoken with them inside that restaurant.
"Do you?" Historia had asked.
Eren had nodded.
Later That Night...
Historia Reiss and Frieda Reiss was currently inside of Historia's bedroom staring at a baby inside of a crib. They were staring at Historia's infant daughter, whom was sleeping.
"Aw, who's this adorable little child?" Historia said as she watched Historia's daughter lie in her baby crib.
"This is my daughter, Alma." Historia said as she had revealed the name of her infant daughter.
"Alma?" Frieda asked.
"I named her after my mother." Historia had informed Frieda.
Frieda happy smile had become mild as she felt a bit concerned when she learned of Historia's daughter's name. "But, wasn't Alma-"
"I know. She was an abusive and terrible mother to me-all the way down to her grave. But for some reason, I kind of like that name." Historia said as she had thought of her last moments with Alma.
"Historia..." Frieda muttered as she looked at Historia.
"I vowed to be a greater mother to my daughter, than my mother was to me." Historia said as she smiled at her daughter.
Frieda looked at Frieda, then smiled. She decided that if Historia was happy, then she would be happy as well.
Meanwhile...
Eren Yeager sat on the front steps on the porch of Historia's house in front of the front door. Just gazing at the night sky and looking up to the stars.
Suddenly, Frieda Reiss had walked outside and met Eren who sat on the porch steps. She stood in front of the front door and Eren's backside was facing her. "Eren. Supper is ready come and join us." Frieda said as she was in a positive mood.
"Yeah. I'll join you in a sec." Eren said as he kept looking at the stars.
Frieda knew that Eren wouldn't join her and Historia for supper right away, like she asked. So, she decided to sit right next to him on the steps. "What's wrong, Eren?"
"When I was a kid, I've always assumed that beyond the walls was freedom. That's why I wanted to join the Survey Corp. And when I had finally made it to the ocean, I've quickly came to the realization that beyond the walls was the enemy." Eren said as he thought of when he pointed his left index finger toward the ocean. "And now all of Paradis' enemies are coming here to destroy Paradis. Not just because of what I did in Marley... but because out of fear for the Rumbling."
"Eren..." Frieda muttered.
"Right now, everyone outside the walls think I'm dead after Marley attacked. But I doubt that's going to stop everyone from attacking Paradis." Eren had assumed.
"Why do you think that?" Frieda had asked.
"Willy Tybur-whose family had the control of the Warhammer Titan had convinced the entire world to declare war against Paradis. All because a non-royal like me possesses the Founding Titan. He was afraid that the royal family wouldn't keep the Founder's power in check. And somehow, he was right." Eren stated.
"I understand..." Frieda said in a soft tone.
"And after I attacked Marley and stole the Warhammer Titan, I thought that I had slowed the entire world down by killing important leaders and officials in Liberio. But all I did was piss off the entire world and get one of my friends killed." Eren had suddenly thought of one of his Survey Corp. friends, Sasha Blouse. "I honestly don't know how we're going to save everyone here. I know that I swore off the Rumbling, but..." Eren said as he looked down at the grass.
Frieda quickly grabbed Eren's left hand. "We'll find a way. Like we always do." Frieda then leaned closer to Eren's left shoulder.
After ten seconds of total silence, Eren decided to change the subject. "I'm going to leave for Shiganshina in the morning." Eren told Frieda.
Frieda gasped. "Are Mikasa and Armin over there?"
"Yeah. Before we came here... Yestersay, I learned from Floch that Armin is helping everyone within Shiganshina District repair the city after Marley attacked. And Mikasa is within Shiganshina, too, but... she gave up fighting as a soldier and decided to live a quiet life, there." Eren said.
"I see... well, I've decided that I'm coming with you to Shiganshina." Frieda smiled.
"But, don't you want to stay here and watch after Historia?" Eren asked.
"I know, but seeing Historia alive and with a family of her own is enough for me. She doesn't need her big sister to pamper her, anymore." Frieda chuckled.
"I guess you're right."
"And also, I'm really curious to see how much Mikasa has grown." Frieda added.
"Oh, that's right. You did try to cheer her up. The "younger" one back when..." Eren said as he then thought of Mikasa as a kid.
Frieda had frowned. "I know..."
Eren stared directly up at the stars and suddenly thought of his parents. "Do you think..."
"Hm?"
"Do you think that my mom and dad from this timeline... would be proud of what we're trying to do?" Eren asked Frieda.
Frieda placed a light smile on her face. "I'm sure they would be. If they were here, they'd probably do the same thing we're doing."
