Chapter Two: The Past Clashes with the Present

Chapter Summary: As Shanks and Mihawk are given clothes to wear, the others have to figure out how they are going to keep Shanks and Mihawk hidden from the world.

No one could say a thing. Completely stunned as Robin told them exactly what she had read. Ace looked back to his parents, seeing their confusion – well, Shanks' confusion since Mihawk's face was indifferent like normal – as they looked at each other. Shanks was still clutching the cloak closed, bringing his pants and sword to his chest again.

Shanks was looking around. His gaze pausing on the Red Hair Pirates who were standing there, gaping at their now smaller Captain. "I recognize most of you… but I don't know any of you." The red-haired Omega stated. At least for the time being, his attention was no longer on Ace or Luffy. Questioning the fact that he had figured out they were related. Ace still didn't have a clue about how to tell him that they were his kids. How to tell him that the very Swordsman next to him was their father. At that age, there would be no way he would remember. A part of him wondered if it would freak him out. If Ace was in that position, he would probably panic being told he had children he couldn't remember.

Rouge smiled, placing her hand on his upper back. "Honey, this is your crew."

Shanks practically looked like he had stars in his eyes as he looked back at them. The red head shook his head, looking back up to his mother. "I actually did it."

Rouge nodded and made a noise. "You did."

Shanks paused, blinking for a second, before he was suddenly jumping up and down. "That means I have my own ship!"

Ace couldn't stop the smile that pulled to his face from the clear excitement that was coming from Shanks. Before they knew it, questions were coming from him. Directed at his crew. At Rouge. Just anyone who was willing to answer anything for him.

Mihawk stepped forward, placing his free hand on Shanks' head to stop him from jumping around anymore. Shanks blinked at him as the Alpha stated, "You are currently not wearing pants, Red-Hair. Keeping jumping around like that and the world will see everything."

Shanks froze, his face turning red for a moment as he looked down, clutching the cloak tighter. "Oh… right." He turned back towards Benn, "What are we supposed to do about clothes? I guess if I'm older my clothes aren't around."

Benn laughed, shaking his head. "We have some clothes in storage." The Alpha motioned for them to follow him. "Let's get you guys into something that actually fits. We should have something for you too, Hawkeyes."

Mihawk hummed, taking a step forward before he was tripping over the edge of his own pants and crashing directly into Shanks. Knocking both of them to the ground. Ace could only blink as he stared down at them. He had never seen Mihawk trip up like that. He placed a hand over his mouth before the involuntary chuckle could leave, shaking his head. Part of him was curious to see what happened from here on out.

Mihawk was there for a second before he was pushing himself up. An almost flustered look on his face for the time being as he mumbled to Benn to take them to get clothes. Shanks pushed himself back up to his feet. Readjusting his stuff in his arms and a grin on his face.

"Before you two break yourselves just trying to walk…" Rouge muttered, "Let's go." She placed a hand on both of their shoulders pushing them a bit towards Benn. Benn was speaking to a few of the Red Hair Pirates. Hongo stepped forward alongside Bonk Punch.

"C'mon, Captain." Hongo stated. "Gotta get you fixed up."

Shanks' face flushed again as he hid his face in the pants in his arm. "That's so surreal."

"Well, get used to it, Boss." Yasopp stated, clapping him on the shoulder.

Ace just watched with a smile on his face as Hongo and Bonk guided the two towards where the Red Force was docked. The uncertainty came to the pit of his stomach as he turned back towards Robin. "There is really nothing that says how to fix them?"

Robin shook her head. "I would like to do a bit more research on the writing on the walls. See if there is anything more that wasn't within plain sight for confirmation."

"What do we do from here?" Sabo questioned. "Shanks-san is a yonko, this will leave him vulnerable. Mihawk-san also isn't as strong as he was."

Benn lit a cigarette between his lips, exhaling the puff. "We won't let anything happen to them. He might not remember us, but he is still our Captain."

Ace sighed, folding his arms over his chest, bringing his shirt closer to him. "This could be a huge issue. How do we just hide them?" Ace stated. "Papa was never one to stay in one place for very long. Mom likes adventure too much to want to just stay on the sea."

Dragon stepped forward, a stern look on his face that he normally always wore whenever Ace would see his face. "The bigger issue isn't just them being seen. Hawkeyes is a Warlord. He's connected directly to the World Government rather any of us like it or not. With the war, the Marines will most likely leave the Red Hair Pirates and Whitebeard Pirates alone. That can't be guaranteed."

Ace turned to look at Whitebeard, an almost pleading look in his eye. "Oyaji… I want to stay with the Red Hair Pirates." He muttered. "I can't just leave them like this if there could be a chance that this is used again them."

Whitebeard smiled at him, large hand back on his back. "Don't concern yourself, son. That brat is family. We'll all make sure nothing happens to the two of them."

Shanks was bubbling in excitement as they got closer to the shoreline. There were multiple ships. One he had immediately recognized as a bigger Moby Dick, which would be Whitebeard's ship. The others he didn't recognize. The one that was red had caught his attention. The jolly roger flying from it have red stripes over the left eye of the skull. He stopped as they got up to it. The appearance of the ship had looked exactly like he had imagined what his ship would look like. This one was just bigger.

He had no words to describe what he was feeling right now. Every emotion going through that was telling him that he had done exactly what he said he would. All he knew was, he might just break down right then and there. There was so much going on. He was apparently supposed to be much older. He had a crew. His mother was here. Just so much going on. He didn't understand what was going on. Why he was even here. From what he could conclude, from his mother's words, he had just came from a war. The last time he had been in anything close to a war was the Edd War with the Roger Pirates up against Shiki and his fleet.

What he was most interested in now was Commander Ace and Captain Luffy. Ace looked similar to his mother and Luffy carried the name Monkey. He was positive that he was somehow related to them. Judging by their appearances, they were slightly older than him for how he was now. He never did get Commander Ace's family name, so he couldn't be positive, but his face had said it all.

"Welcome home, Boss." Hongo stated as he motioned towards the ship. A smile on his face. "This ship has been our home for a long time."

"What's her name?" Shanks questioned, eyeing the ship, looking over to Hongo with curiosity.

"Red Force." He replied.

Shanks grinned.

It was perfect.

"Alright, just get you guys some clothes, and we can get back to the others." Shanks nodded, following behind them.

As they walked throughout the ship, following behind the two Red Hair Pirates, Shanks couldn't help but look around in complete awe. He still couldn't believe this. That this was his life in the future. That he was a Captain. Had his own ship. It looked like he had everything that he had ever wanted in his life. He wanted to know more about what he had become.

"Is there enough red around here?" Mihawk questioned.

Shanks snorted, looking over to the Swordsman as they got guided into what he would guess was a storage room. "What? Don't like red."

"There's only one red thing I particularly like." Mihawk stated.

Shanks laughed, during his attention back to the two older men. Hongo opened one of the boxes, shuffling through it. "Yeah, this is the box." He stated, turning to face them. "Pick out what you want to wear for now and we'll move this up to your quarters later."

Shanks hummed, putting off Mihawk's comment for now, walking over to the box and taking a peek inside. His eyes immediately met a pinstriped shirt and brown pants that he was used to wearing. A smile came to his face as he grabbed them. He paused as he noticed black pants and black button up shirts that remained him a lot of what Mihawk wore. What he didn't get was, why would they be on his ship?

"We'll leave the two of you alone to change." The other pirate – he believed was Bonk Punch. He really loved that name. Of course, he would have someone with an odd name with him. He always enjoyed the oddities of the world.

"Thank you." Shanks stated, grabbing a discarded red sash, sandals, and a pair of boxers from the box too. The other two excused themselves completely from the room, leaving the two completely alone now.

Mihawk had grabbed some of the clothes him, eyeing them for a second. "These are mine."

Shanks shrugged. "Maybe, you left them here."

"Now, why would I do that?" Mihawk questioned, turning his back, and slipping out of the coat that was on his shoulders. The Alpha sighed after a second. "I guess it doesn't really matter."

Pulling on the button up next. Shanks placed the pants and sword he was still holding onto down, letting go of the cloak. The shirt he was wearing went almost to his midthigh, keeping him concealed but his face was heating up at the thought that Mihawk – an Alpha – was standing right in the same room as him. He turned without a second thought, slipping the other clothes on. They fit his form perfectly. Like they were his clothes. The thought crossed his mind to why he would keep ahold of his old clothes for so long. It worked in his favor, he supposed. The Omega slipped off the cloak and button up shirt, pulling the other shirt on and tying the sash over his waist.

He stopped as he looked back at the sword he had. It was long. Way to long for his abilities now. There would be no way that he could even be able to use it properly. He would need to get ahold of a new one for now. From the sounds of it, they might be able to reverse this. He would need something he could use properly until then.

Readjusting his clothes and making sure he was in place, he turned to see Mihawk already at the door. The jacket he had been wearing before was back on him, the large black sword on his back.

"Let's find some answers, Red-Hair." Mihawk stated.

Shanks smiled. "Yeah, I guess." He paused for a second, shuffling on his feet. Being around the Alpha felt nice. He couldn't place it. Maybe it was because they had been spending time together recently outside of just their normal duels. It was like he was getting to know more about the mysterious Swordsman. He reached up, grabbing at his mother's necklace. Stopping when he realized he had grabbed two.

He brought the pendants into his hand. Recognizing one as his mother's and the other he didn't know what it was. It was clearly specially made with a cherry blossom on it. He blinked, shaking his head at the thought before he was tucking them under his shirt. For all he knew, it was simply just a piece of jewelry. As long as if he had his mother's still, that's all that mattered.

"Well, come on." Mihawk stated, opening up the door and motioning out.

Shanks exaggerated a swoon. "What a gentleman."

Ace still was unsure what to think. He had started pacing around, picking at his nails as he moved. "Ace, calm down." Marco stated.

The Omega looked over to his mate to be with a frown. "How can I?!" Ace exclaimed. "My parents are small! Well, not that small but small." The Omega sighed, rubbing at his face again. They had been going over a course of action this entire time. Trying to figure out what they could possibly do in this situation.

Shanks, Mihawk, Bonk, and Hongo should be back soon enough, but it felt like anxiety was spiking in Ace. He wanted to scream at the world. He wanted to understand why this had to happen. He didn't understand it. They were finally finding some peace and it seemed like the world was throwing yet another curve ball at them.

It surprised him mostly watching that Shanks and Mihawk were taking the news relatively calm. For some reason, he felt like he was the only one that was panicking over what was happening.

"It really can't be that bad." Luffy stated, hands behind his head.

"Of course, it is!" Ace exclaimed. "Our parents are literally younger right now than I am! What if they get discovered?! What if we can't fix them—" The Omega choked for a second, stopping in his tracks. "What if we don't have our parents anymore?"

Marco sighed, walking forward, and placing his hands on Ace's biceps. "They are safe, Ace." He said, "We will find a way to fix them. A lot of us probably understand to an extent about what you are feeling right now. The Red Hair Pirates certainly would."

Benn smiled as he walked up next to Marco. "We are probably freaking out just as much as you, we just aren't showing it. That's our Captain." He took a drag from his cigarette, exhaling the smoke as he added, "If we panic, we will panic them. It's best to remain as calm as possible. The sooner we figure this out, the faster they will be back with us."

Ace nodded, exhaling sharply. He shook his head, looking back over to where Shanks and the others had disappeared towards the Red Force. "I just…"

"It's okay to feel something about it, Ace." Rouge stated. "This isn't exactly a typical situation, but everything will work out in the end. I'm sure of it."

"This is weird." Sabo stated, sighing as he leaned back against the nearby tree. "I never thought I would see them that young."

"Does anyone really?" Koala questioned.

"I gotta agree with Sabo." Yasopp said, "This is really weird to see. Time sure does fly, doesn't it?"

Ace sighed, leaning forward into Marco's chest. It didn't help the anxiety that he was feeling but he was right. They were safe with them. "It'll be okay, Ace."

"I hope so." Ace whispered, wrapping his arms around Marco's torso, and leaning his head against his chest. He relaxed as he felt the fingers moving through his hair. He inhaled Marco's scent, taking the moment of peace that he could. They had so much to deal with now.

"It's kind of funny that Red-Hair already started to recognize Ace and Luffy." Thatch snickered.

Ace peeked around Marco's arm to the other Commander, seeing the smirk on his face from where he had his arm thrown over Izou. "This is going to be hard. Trying not to tell him who we are."

"Why don't you? Wouldn't it be easier on all of you to just… I dunno, tell them the truth?" Thatch questioned.

"I don't want to freak them out." Ace replied.

Rouge laughed, leaning over Ace's back, and nuzzling at his ear. "Honey, he'll figure something out." She stated, pulling away, a grin plastered on her face. "Did I ever tell you what happened the second he met his father?"

Ace shook his head, intrigued already. "What happened?"

"He recognized Roger as his father just by looking at him. Of course, I told him his father's name, but I never showed him a picture of him." Rouge explained. "When Roger showed up in the West Blue just after Shanks turned four… it was almost instant. The bond between a parent and child is strong. Rather you tell him or not, he'll probably figure it out."

Ace shrugged, leaning back towards Marco again. That feeling was still there. He wanted his parents back as his parents. Not just the forms of their teenage selves. "This is going to be interesting." He whispered.

"Hey, they're coming back." Luffy stated.

Sure enough, coming over the small hill were the four. Shanks and Mihawk were now dressed in better fitting clothes. What Ace didn't overlook was how Shanks and Mihawk were talking to each other. Soft smiles lingering on both of their faces. Mihawk wasn't necessarily talking, hands in his pockets as he walked. Shanks had almost a hop in his step as he was chatting away. Ace let the smile come to his face. Some things never change.

Shanks turned his head, pausing as his eyes landed on someone. Ace couldn't see who he was looking at through the mass amount of people standing around. The Omega grinned, laughing slightly before he yelled out, "Buggy!" By the look that came to Shanks' face, it looked almost like relief. "You're…"

"What? Did you think I was going to die?" Buggy questioned.

Shanks shook his head, breaking away from Mihawk to rush over to where Buggy was standing. "No—just… I'm really happy to know you're okay." Shanks stated. "When the crew…" The red head's voice trailed off as he looked to the ground. The motion almost looked like Shanks was trying to conceal his face, but he didn't actually have anything to do so with. It almost looked like longing was plastered on his face.

"They are fine as much as I know." Buggy stated. "Crocus-san is on Reverse Mountain with Laboon. Rayleigh-san is on Sabaody Archipelago, and Oden-san returned to Wano." Shanks' face seemed to light up again, a smile coming to his face from the mention of his three former crewmates.

"That's good to know." Shanks stated, placing his hands behind his back, interlocking his fingers. What caught them all of guard was Shanks suddenly moving forward and wrapping his arms around Buggy's torso, his nose buried in his shirt as his shoulders shook. Buggy looked stunned, looking unsure of what to do before he nervously placed his hands on the Omega's shoulders.

"Okay, bastard." Buggy stated. "You can let go now."

Shanks shook his head. Mihawk stepped forward, placing it hand on the top of Shanks' head. "He's not going to disappear if you let go." Ace could only watch on in surprise. Watching as Mihawk coaxed Shanks to let go of Buggy completely. The Omega placing a smile on his face, but his eyes read something completely different.

Buggy reached out, placing his hand on Shanks' shoulder. "The same old red-haired bastard."

Shanks snorted, shaking his head. Rouge walked forward, motioning for the others to join them. "C'mon, time to eat. We were just about to eat lunch before departure."

Ace pulled away from Marco, smiling up at the Alpha before he was walking over to his parents. "Well, now that you're properly dressed, I'll formerly introduce myself." He stated, bowing down slightly. "As I told you before I am Whitebeard's current Second Division Commander." He stated, standing back to his full height. "If you need anything, all you gotta do is ask."

"Ace, right?" Shanks questioned. Ace nodded, smiling softly. The red head laughed slightly, grinning as he tilted his head. "That's my dad's sword's name. It's a nice name. I like it." Mihawk snorted causing Shanks and Ace to look at him. "What?!"

Ace blinked, he didn't actually know that information. He was named after Roger's sword?

"Ace is named after Gold Roger's sword?!" Luffy suddenly exclaimed. Ace moved quickly, clapping his hand over Luffy's mouth. Muffling the rest of the words that were coming out of his mouth.

Shanks was looking at him now. Mihawk's eyes were narrowed again on the two of them as Ace tried to laugh it off. "Don't listen to him. He's just a knucklehead." Ace cast his brother a look, shaking his head as he looked back over to Shanks and Mihawk to see the contemplating look on Shanks' face.

The red-haired Omega was approaching them again. Eyeing them for a second before Luffy managed to rip Ace's hand away from his mouth. "There's something I want to give back to you!" Luffy stated.

It had Shanks stopping in his place as Ace let Luffy go completely. Luffy was grinning as he reached up, pulling his hat from his head. Ace could only watch in disbelief as Luffy reached out and placed it on Shanks' head, almost hitting the Omega in the eyes with the inside of the hat. "Luffy…" Ace whispered. He hadn't actually expected Luffy to do it.

"We made a promise on this hat." Luffy stated. "I promised I would return this hat the second that I became a great pirate. I'm not there yet, but that promise isn't there if you don't remember it, right?"

"A promise?" Shanks whispered as Luffy pulled away. It was almost surreal to see that Shanks was actually shorter than Luffy was.

Luffy laughed, placing his hands on his hip. "That's why you gave me the hat. I don't really know what actually led to it because you used to tell me you could never give it to anyone." The Alpha explained. "But once we get you back to normal, you gotta give it back to me. Our promise won't be fulfilled until the second I become the King of the Pirates."

Shanks inhaled sharply, eyes wide as his gaze snapped up to meet Luffy's. "What did you say?"

"I'm going to be King of the Pirates!" Luffy exclaimed.

It was like Shanks and Luffy were in their own little world. Not a word being said between the two of them before Shanks had tears in his eyes, laughing as he reached up to wipe them away.

"Are you okay?" Luffy questioned.

Shanks nodded. "Yeah." He paused as he reached up and touched the brim of the straw hat, adjusting it on his head. "You just reminded me of someone."

"Let's go get some food and we will tell you what we decided on." Rouge stated.

Shanks smiled, looking back to Ace and Luffy again. "I want to know about you two." He said. "Mind if we talk?"

Ace shook his head. "Not at all."

This was going to be exceptionally hard. Ace knew that much.
