* SEARCH AND RESCUE *

The door burst open and a panicked stricken Conny appeared in their meeting room.

"Commander Hange, Captain Levi, Eren... Lieutenant Bella has been abducted by the Marleys!"

Cold sweat and fear flooded his system. He felt rage and horror. He stood there in shock. His blood boiled and he have to find Bella no matter what happens.

His thoughts were snapped back to reality when Eren stormed towards the door but was delayed by his comrades, who he pushed hard aside out of his way.

He reached Conny and grabbed his collar, "What the fuck Conny, tell me you're lying."

Conny grabbed Eren's wrist to stop him from strangling the life out of him.

"We were patrolling and titans came out of nowhere. The cart titan appeared and grabbed your sister in her mouth. She emerged from the body to tell us that she's being hostage."

"In exchange for what?" Eren said between his gritted teeth.

"You."

That's when Levi jumped into action because he knew that Eren is a suicidal maniac and he was also an idiot.

He pinned him down in an instant while Armin held Mikasa back.

"Eren, we'll get her back," he said calmly.

"They have Nee-san because of me! Let me go, Captain," Eren exclaimed.

He pushed him harder on the ground, "Do you think they will let your sister go if you turn yourself in? No. They'll torture her for information or even make her Titan food. So we'll get her," he said firmly.

"And I'll kill the bastards who took her," Eren added in anger.

"Oh we sure will, that's a promise," Levi thought to himself.

They maneuvered through the underground city easily, thanks to Levi who knew the place very well. He also had connections deep within so they used it to their advantage., and with his reputation, the officials knew better to cooperate with him than the threats given by the Marleys.

They saw the cart where they must have taken Bella and they also knew that the Cart Titan would be around somewhere as it is the only titan that could move around the place, except that they didn't know that Ymir would also be there.

That made it more difficult than they have anticipated.

Sasha and Conny knew Ymir's weakness and they disarmed her easily by reminding her about Historia while Hange and Mikasa handled the Cart Titan.

Levi pursued the cart while Jean took point.

Hange and Mikasa gave him the opening that he needed and Jean was able to aim perfectly at the ropes that tied Bella to the frame above her head which gave her the chance to attack the soldiers guarding her.

Except one of the soldiers was Reiner and he had both of his arms locked around her throat and chest in an instant.

She knew she had to play it smart because he can't go titan at this place.

Jean aimed at the wheels and it made Reiner lose his balance and Bella did her best to get out of his arms.

Levi made it just in time and swung to grab Bella by her waist and she grabbed on to Levi for her dear life.

Jean fired the signal and they scattered to get to the exit points and meet Eren and Armin at the rendezvous point.

Bella kept her arms locked around Levi's neck while Levi held her securely close to him, thankful that he came to get her.

As soon as they got to the rendezvous point, Bella ran straight to Eren and Armin and hugged them tightly. Eren caught her in his arms, thankful that she was safe and sound.

They returned to their base safe and sound, stomachs growling in hunger, bodies aching in exhaustion.

Bella turned to the group and bowed her head in gratitude and they smiled at her.

"We can't lose you, Lieutenant," Jean replied with a soft smile.

"And surely we'd come and get you anyway. Because we'd rather rescue one person, rather than these three idiots who would go after you," Hange joked and pointed her finger at Eren, Mikasa, and Armin.

They all had dinner and Levi headed straight to his quarters.

Then after a couple of minutes, he heard a soft knock on his door and someone entered. He knew who it was.

"Thank you, Levi."

"I was only doing my part or else Eren would go on a suicide mission, Mikasa and Armin would surely follow and it'll be harder to rescue 3 idiots and 1 actual hostage."

She chuckled softly because she knew that he can't handle moments like this one.

His heart skipped a beat from the sound of her voice.

"I knew that. But, I also know that you'd be the one who would come and get me. Not Eren, because my idiot brother would surely get captured or beaten up somewhere. Not Mikasa or Armin or Hange. I knew it would be you."

"Well, I'm the most skilled one who wouldn't get you killed."

He didn't expect the next thing that happened.

Soft arms wrapped gently around his torso. She was hugging him from behind. She felt warm and soft and her voice sounded so mellow and feminine as she whispered, "I was scared that I won't be able to see you again."

He relaxed in her embrace. He can give himself this. He can't lie to himself that he was about to go on a suicidal mission to get her, but Eren snapped him out with his outburst of panic and anger.

"Me too," he mumbled very softly, almost inaudible that he was sure she wouldn't hear him.

But she did and she smiled.

* THE HANGE ZOE TALK *

"Such a long day," Hange collapsed on her chair in front of Levi who was cleaning his dagger.

"Seems like the Jaegers have something in common - Tenacity & Principle," Hange said.

Levi raised an eyebrow for her to go on.

"Zeke is a persistent fucker. I bet he's a smart one, too. Based on Yelena's intel, he has a grand plan that would save the world. Bella is the most decent of them. She's reasonable and level-headed, strong and a skilled fighter and will do what is morally right, even if the odds are not favorable to her. And Eren, a suicidal idiot, who has his intent fully on killing all titans in the world."

"All of them are suicidal maniacs, too. Bella included," Levi added, "The number of times that I saved her ass from getting killed because she rushed head-on without thinking during our missions."

"I was dumbfounded at how many daggers she has on her body because she knew that our swords would eventually wear out. She'd constantly run out of gas and we'd come and find her somewhere in a tree or hanging from a titan's head, not killing it yet because she ran out of gas," Hange recalled.

"Bloody idiot."

"But she saved our asses multiple times as well."

"Even at her own expense."

"She thought joining the corps would keep Eren from joining, but it only excited him more. I bet she's the most talented of the three, even without titan ability, she's already lethal. They must have slipped something to capture her that day because she can remember passing out."

"She gave me this scar during the training. She's a talented fighter, I'd give her that."

"Is that why you like her?"

He choked on his tea when Hange blurted out the question out of nowhere.

"What?"

"It's so obvious, Levi, Even Conny, and Sasha would've noticed it."

"I don't-"

Hange patted his shoulder, "Everyone knows and you two are stubborn idiots."

"Again, I'm not -"

"It's understandable. All the guys in her batch were smitten with her. Even Erwin and Miche liked her at some point. She's beautiful, strong, and talented."

"Shut up."

"Oh hush now. She only has her eyes on you."

He choked on his tea, again.

"I told you it was obvious. Plus the undeniable tension between the two of you was as thick as Armin's titan."

"Shut up," he sipped on his tea to hide his blush.

* THE FINAL TALK *

"Onee-san, forgive me."

"Eren, what are you planning to do?"

"I'm leaving it all to Zeke."

"No, you can't. We'll find a way. We always do. Just, don't go... Please," she pleaded.

"I have already decided Nee-san," He answered decisively, "You can't change my mind."

Bella grabbed Eren by his shoulders to face her. She grabbed his face firmly and caressed his cheeks, "Please Eren, don't leave me. Please talk to me. Tell me what's in your head."

Eren placed a hand on his sister's arms, "I can't Nee-san. I have to protect you. If you know, you'll be dragged in the middle of this. The less you know, the better survival chance you'll get."

"I can take care of myself, Eren. I can't lose you, too," she sobbed, "Please."

"I love you, Bella-Nee," Eren said and gripped her wrists, "That's why I have to do this. Please, survive. I love you so much."

He forced her hands off his skin and ran to the crowd to getaway.

"No no no no, EREN!"

She ran after him but with the crowd, she can't find him. There are so many people. She is panicking and she kept on running and shouting his name.

"EREN!"

He's gone. She lost him in the crowd. She lost him. Her little brother.

She knew she had to find him, but she also knew that she won't be able to do it alone. She ran back to their accommodation only to find her comrades in panic as well.

She collapsed on the ground and sobbed which caught the attention of everyone in the room.

Armin and Mikasa rushed to her, arms soothing her back.

"Nee-chan, where is Eren?"

She shook her head and broke into tears in Armin's arms.

"He left. He said he'll leave it all to that piece of shit who is our oldest brother."

Armin cradled the woman who he treated as his older sister, his family.

"Armin, what do I do? I can't lose my younger brother. I don't know what to do!" She cried, "Damn that Zeke. Damn him! Damn it all!"

Mikasa hugged Bella to help her calm down despite the boiling anger she feels inside for Zeke.

"We'll find him, Nee-chan. We'll find and talk to him," Armin said calmly, "We'll find him, Nee-chan."

Levi just stood there, watching as he clenched his fist, knuckles turning white, as he fought the strong urge to take her in his arms and whisper promises to make it all better. But he can't. Those are going to be empty promises. He can't make it better. But he is a man who holds grudges and takes the will of his fallen comrades.

All he could do right now is to stand there and curse Zeke and Eren.

And he vowed that he'll make Zeke pay for everything that he did to the people around him.
