Shortly after returning to Shiganshina within Wall Maria, Eren Yeager returned to the home he stayed in when he was a kid. He stood outside and stared at his house from top to bottom. While staring, he started getting flashbacks of the day when his mother, Cala Yeager being trapped under the boulder and house debris, then he remembered her being devoured by Dina Yeager. Images played of the incident played within his mind.

Eren closed his eyes and exhaled, then open them with fire inside green raised his left hand in front of his face and sunk his teeth in it. After biting his own hand, Eren's entire body began to glow the color of white, rather than yellow.

Four Days Later

The time was eight in the morning and the sky was blue and clear. As Eren Yeager had returned to the capital of the walls, Mitras on horseback, Frieda Reiss had stood in front of the castle entrance waiting on him. After Eren had ejected himself from on top of the horse carriage and landed on the ground feet first. He then looked to his right to see Frieda approaching him.

"Hey, Eren. Were you able to take care of your business?" Frieda asked.

"I have." Eren nodded. "But there's something you should know..."

"What is it? You didn't get into any fights or messed with any girls, down there in Shiganshina, or have you?" Frieda asked with a little bit of sass within her voice.

"What? No. Neither of them. But while I was down there..." Eren rubbed his left ear with his right index.

Frieda stared at Eren while he rubbed his ear. "You're rubbing your ear again. What's going on?"

"I took the liberty and personally invited someone to come here." Eren said.

"Is it one your old friends? The one called Armin Arlert?" Frieda asked as she once remembered seeing a younger Armin Arlert in the crowd when she was leaving the walls.

"No. When I was in Shiganshina, I told him to stay home for a while, because the younger me and Mikasa weren't around for the time being. Bullies were looking for him." Eren walked towards the horse carriage door. "But, you might be surprised whom I brought along with me."

"Who is it?" Frieda asked.

Eren continued to look at Frieda, the muttered out some words.

As Frieda heard his words, her ears had suddenly muted, and her eyes had grown big a bit.

Eren opened the horse carriage door, then looked inside. "It's okay. You're safe here." Eren said as he extended his hand out.

"Okay... I am ready." said a feminine voice.

'That voice... could it really be-' Frieda Reiss carefully watched as Eren escort a woman out of the horse carriage and set her feet onto the ground. Her eyes widened in shock as she gazed upon the woman that Eren had brought with her. The woman that Eren had brought was no other than his own mother, Carla Yeager. She looked exactly how she was when Frieda had met her. She still wore a dark red long skirt, and a white apron over her yellow long-sleeved shirt. But she was not wearing any shoes.

Carla Yeager had looked around her surroundings and noticed a large castle building. "Are we inside the capital, Eren?"

"Mm-hmm. We're inside Mitras." Eren nodded, then looked forward and pointed towards Frieda. "And the woman standing right there, standing right in front of us is no other than Queen of the Walls and my fiancé. Frieda." Eren

"Oh? Frieda?" Carla then looked and spotted Frieda.

Frieda stood still as she was completely shocked to see that Carla was alive and well. The last time she heard of what happened to Carla was when she had been killed. But now she's alive and well.

Carla slowly walked towards Frieda and smiled. "Good morning, Lady Frieda. My name is..."

Frieda instantly ran and hugged Carla. "Miss Carla!" Frieda cried.

Carla lightly gasped as Frieda had embraced her. She did not expect the reaction she had been given by Queen Frieda.

"I missed you so much..." Frieda rested her chin onto Carla's right shoulder and cried. A stream of tears ran down Frieda's face as she was happy to see that Carla was alive and well.

Carla can tell that Frieda deeply cared for her as she can easily hear soft sobs and the way Frieda was hugging her. "Well, it's nice to see you, too." Carla then rubbed Frieda's back, softly.

Eren watched his mother and fiancé embrace and he couldn't help but smile. The embracement continued for another fifteen seconds until Eren decided to call it enough. "Um, mom. Frieda. We should be visiting the others, soon." Eren told both Carla and Frieda.

Carla wiped her tears with her sleeve and looked towards Eren. "Oh. You're right. Sorry. This way." Frieda then led Carla Yeager inside the castle, as the Adult Eren had followed behind his own mother.

One Minute and a Half Later

Carla roamed the castle with her adult son and Frieda Reiss. She was unaware that Frieda was leading her toward the infirmary where the younger Eren Yeager and Mikasa Ackerman were inside of.

"Where are my children... Eren and Mikasa? Are they alright?" Carla asked while feeling concerned them. Carla is fully aware that her and Mikasa are not related by blood daughter, but she had always valued Mikasa as a daughter.

"They are currently in the infirmary." Frieda answered.

"The infirmary? Did something happen to them?" Carla asked.

Frieda gulped a bit. "Mikasa is okay. But Eren... his body's resting after suffering a few critical injuries."

Carla horrifyingly gasped. "C-critical injuries? Is Eren alright? What happened to him?"

"Well... an incident had occurred recently that resulted in your younger son getting kidnapped and physically assaulted." Frieda said in a sad tone.

Carla horrifyingly gasped and stopped walking. "What?" she muttered as her eyes had grown bigger.

"Yes. He was assaulted by a man who did horrible things to people." Frieda thought of Kenny Ackerman when she remembered when she first saw Kenny Ackerman during a prayer session a few years prior. "We managed to find and rescue him before anything terrible could happen. And..."

The Adult Eren coughed a bit. "What Frieda is trying to say is that... the younger me is safe. And that the ones who were responsible for his kidnapping are not in custody." Eren thought about Rod Reiss and Kenny Ackerman.

Carla then sniffled and wiped her eyes after hearing what her adult son said. "Thank heavens."

Another minute had pass and Frieda had finally led Carla to the infirmary where Eren and Mikasa were.

"They're in here." Frieda said, quietly before she raised her hand to knock on the door.

Meanwhile, on the other side of the door were two children. A ten-year-old Eren Yeager, who was currently bedridden and wide awake. Also, a ten-year-old Mikasa Ackerman was in the infirmary watching over Eren's ridden body like a hawk. She sat in a chair and watched him. Suddenly, they both heard knocks coming from the door.

Mikasa turned half her body towards the door.

Eren lifted his head a bit to look at the door.

"Eren! Mikasa! You have a visitor!" Frieda called from the other side of the infirmary door while knocking.

'A... visitor? Is it Armin?' Eren thought to himself as he tried sitting up.

Mikasa turned back towards Eren only to see him try to sit up, completely. "Eren. You shouldn't try to move from bed. You need to rest your body as much as possible." Mikasa told Eren as she helped him lie back down.

Eren grunted a tiny bit. "I know that Mikasa..." Suddenly, the infirmary door had opened. "I just wanna know who's-Eh?" Eren suddenly looked to the door for a split second. He then gasped as he noticed someone had walked in the room and looked at them.

Mikasa stared at Eren, who had a look of shock on his face. 'Eren?' She then turned her head in the direction where Eren was staring and gasped in shock as well.

"Eren... Mikasa..." Carla called them both by their names with. She had orbs of tears within her eyes.

Both Eren and Mikasa gasped and instantly recognized Carla. They both were shocked, surprised and confused. The last time they saw her alive was before Kenny Ackerman cut her throat in front of them. Now she looked much alive and well in front of their eyes. They didn't know what was going on, whether she had come back from the dead or something else."

Mikasa took action by removing herself from the chair she sat in and ran towards her foster mother, Carla Yeager. "Miss Carla!" Mikasa screamed as she made contact with Carla's waist and started to cry in relief. She clung onto Carla's lower left shirt and dug her face into Carla's left side.

Carla then looked down at Mikasa as she heard her crying. She then patted Mikasa on the back of her head. "It's okay, Mikasa. Everything is going to be alright." she said in a calm voice.

"M... mom?" Eren muttered.

"Hm?" Carla looked up to see Eren sitting up in bed and staring at her like a ghost. "Hmph." Despite Mikasa clinging onto her left side, she slowly walked towards the infirmary bed that Eren was sitting in.

As Carla slowly walked toward him, Eren started receiving random flashbacks of the times when he mistreated and talked back to her. Most of them were about Eren wanting to join the Survey Corp. Now, he is starting to regret ever treating her that way. He remained silent and looked away a bit.

"Eren?"

Eren slowly looked at Carla's extended right hand, then looked at her face when she saw a kind smile and a stream of tears run down her face. Eren had imagined a golden light shining behind her as she smiled at him. He slowly took Carla's hand and then gasped when he felt a pulse. He knew it was real and he knew that his mother is alive.

"Hm? What's wrong, Eren?" Carla asked as she can see that Eren started to become visibly upset.

In the next moment, Eren had instantly jumped and hugged his mother by wrapping his arms around her neck, despite Mikasa still crying and clinging onto her left side. "Mom!" Eren shouted as he let tears of sorrow and grief out from his eyes.

Carla then rubbed Eren's back with her free hand, as she "There, there. I'm here."

"I'm sorry, mom... I'm sorry for talking back to you! And that... I took you for granted! And I'm sorry I wasn't strong enough to protect you!" Eren cried and snot started to run down his nose.

"It's okay. I know you are." Carla let tears of joy stream down her feminine face.

"I'll never disobey you, again!" Eren yelled as he sobbed.

"It's okay. All that matters, now, that you're both safe. You and Mikasa." Carla said in a soft tone as she continued to hug her children.

As Carla Yeager reunited with her children, the Adult Eren Yeager and Frieda Reiss watched everything from the cracked infirmary door.

"This really precious." Frieda's eyes watered in joy.

Eren remained silent.

"Eren."

The Adult Eren heard his name called and looked to see his father, Grisha standing in the hall. "Dad."

"I came to find as soon as learned that you had returned. What is so urgent?" Grisha asked.

"You're about to find out." Eren said, then looked back through the infirmary door and kept watching his mother, Carla embracing his younger self and Mikasa.

The Next Chapter... you will find out how Carla Yeager came back in the picture.

Also, some might be confused of which Eren I'm talking about. When I say Eren hugging or reuniting with Carla in the infirmary, I'm referring to the "younger" Eren Yeager.
