Later on that day Law the crew were having their rowdy dinner as usual, it was mainly wrapping up and Law stood overlooking the deck in the breeze. Leila was happily having a drinking competition with Shachi and Jean, Jean acting as the voice of reason and Shachi and Leila egged each other on. The two had found a good friendship whilst she spent her time on the ship, they both enjoyed the fun the other proposes when drinking and they often had training fights – which Leila often won.

Bepo took his place next to Law, shifting uncomfortably on his feet, obviously wanting to say something.

"Bepo, if you have something to say just spit it out" Law said calmly.

"U-um, well Captain." Bepo began, looking at Law cautiously. "About earlier, I'm sorry I walked in. I thought you were alone, I didn't realise you and Leila were like that…"

Law sighed and paused for a minute. "Its fine, we should have been more careful"

"Captain, do you like her?" Bepo asked genuinely, feeling like he may be overstepping his boundaries but he was attentive enough that he noticed a shift in Law's behaviour. Sometimes he was more on edge around Leila, other times Bepo would catch him looking at her softly.

Law stiffened slightly and he let out a long sigh. "It's not like that Bepo, it's just casual. Like it always is"

Bepo eyed his captain warily. "You've been acting strange though captain. The fact you even let her on the sub was odd…"

Law looked Bepo in the eyes, making the bear sweat slightly. He respected his captain but sometimes he couldn't tell what was going on inside his head. Law smirked before taking a swig of his drink. "I know what I'm doing Bepo. Besides, she's a beautiful girl – can you blame me for being caught up for a little while?"

Bepo cleared his throat as he recalled the scene he had walked in on earlier, more confusingly, the heavy atmosphere. It was suffocating to him. He thought for a minute about his Captains behaviour – he was used to many women being on board the ship for a night at Law's wishes, but he knew his captain wouldn't get involved with a crewmate. 'He'd feel trapped…' Bepo thought to himself before Shachi interrupted his thoughts; he walked out onto the deck with tears in his eyes from laughing so much.

"C-captain, watch this" Shachi said clutching his stomach. He beckoned Leila to come out who followed him tipsily, her cheeks flushed from the alcohol she had been consuming for the past hour.

"Oii, why are you getting ya captain involved?" Leila giggled, pointing her finger at Law.

"D-do it again I beg you" Shachi chuckled, wiping tears from his eyes. Jean came out onto the deck also with a large beer in hand.

"What's so funny then?" Law asked, mildly annoyed that she was getting on so well with the male members of his crew.

"She was trying to do an impression of Zoro, but my god she's just so bad" Shachi said

"Oi oi!" Leila taunted Shachi, standing up to do her impression. "Let the captain decide for himself". Leila unbuttoned her blouse a couple of buttons and ripped it open as much as she could to reveal a considerable amount of cleavage and Law's eyebrow twitched in confusion. Leila put her weight on the back of one of her heels and put her hand on her hip, imaging swords at her hip as she squeezed one eye shut. Her stance made her look like she was impersonating a thug.

"OniiiiGIRI" Leila shouted, spinning in drunken circles quickly, crouching low and looking more like a confused hamster. She easily lost her footing and fell onto her ass, still keeping her eye squeezed shut. She smirked up at Law and held up gang signs - "Santoryu bitch"

Shachi burst into laughter once more. "You're such an idiot, why were you spinning like that?"

"Is something wrong with your eye?" Jean asked seriously, making Leila pout at him like a kid.

"Forget it Jean….you don't get it. Law! What did ya think, huh?" She grinned up at the captain from the floor, looking like a flushed mess.

"Yeah…don't ever do that again" Law said coolly but he retained a playful glint in his eye, somewhat enjoying the commotion.

"Hmph…fine" Leila crossed her arms in defeat. "Why does he always scream for a rice ball anyway…."

"Bahahah, you're such an idiot!" Shachi continued to chuckle, helping her off of the floor.

Leila got dragged out of bed early in this morning by Law and most of the crew was settled on the deck.

"Heyy, I'm hungover why do we have to do this now?" Leila complained, wrapping a large hoodie around her arms. She had been using Law's ….'lady friend's' clothes – much to her disdain, but she really didn't have anything else. She washed them all thoroughly, two times over, and she still felt somewhat dirty for wearing them. The sub had been surfaced for a couple days to allow the crew to get some air, they were still in icy waters but they were slowly moving towards warmer islands.

Law leant against the edge of the ship and assessed Leila up and down. "Why not now? It's a good of time as any"

"I don't need any training…" Leila huffed, her cheeks puffing up cutely.

Law scoffed at her. "Yeah, tell that to Bepo"

Bepo blushed furiously as he recalled the foggy atmosphere he had walked into, and nearly succumbed to the day prior. Leila just glared at the handsome captain before uncrossing her arms, facing Penguin who had been chosen to be her first opponent. He stood slightly nervously, not quite knowing what to expect and he was a bit apprehensive about going all out towards a girl. Law knew this quality in Penguin, which is precisely the reason he had picked him.

Law had urged Leila to train with the crew as he wanted to see the extent of her devil fruit abilities. He had caught onto the themes of her mood swings - she possessed the Satan Satan no mi, a devil fruit that could allow the user to experience 7 of the deadly sins - 'pride, greed, lust, wrath, sloth, envy and gluttony'. He had witnessed her use lust and pride and he was eager to see if she could use the others. By their brief conversations it seemed like she could but Law wanted to make sure. She evidently struggled to control it - it could prove dangerous to those around her, like Robin mentioned.

"You can move first" Leila told him, pulling up her sleeves so her arms were bare. Penguin staggered slightly when he saw her many scars but alas, he picked up a spear and ran swiftly towards Leila.

Leila stepped sideways but allowed the spear to graze against her arm, creating a deep gash that instantly oozed blood. Penguin smiled slightly as he thought he had successfully made a hit and he looked towards Law to see some kind of pride for his crew – but found none. Law was concentrating mainly on Leila, he showed no sign that he was about to praise Penguin anytime soon.

Leila let her devil fruit abilities manifest in front of Law's crew – who had never seen it in action before. She held out her hand and the droplets of blood formed a light katana this time. Law raised an eyebrow slightly as he had never seen her wield a katana before and she moved it around swiftly in her hand, finding a comfortable positon.

"W-wha…" Penguin stammered, wide eyed in shock. "Isn't that cheating?!"

"Yeah, kinda" Leila smiled at him before making a quick dart towards his throat to which he fell back in an attempt to dodge it. "Don't go easy on me now Penguin…"

Penguin gritted his teeth before chucking his spear aside, taking up a karate stance that he often used alongside Bepo. He was much more comfortable using his fists, after all. The two engaged in close combat, with Bepo weaving her katana's strikes skillfully, limiting her movement to be on the defense as his fist struck her small frame. However, Penguin was easily on the losing end. Leila was holding back on him, and Law could tell. She made small cuts and nicks at his skin, but she didn't wish to hurt him.

Law cleared his throat and picked up his own sword to prepare for a duel. "Alright, Penguin that's enough. You did good" Law confirmed, nodding at his crewmate. He was pleased that he went all out against a woman, disregarding his own pride. Penguin happily nodded, feeling pleased and stepped aside for Law.

Leila eyed Law warily as he slipped off his shirt, his olive skin and hard abs making Leila's gaze slightly preoccupied. "You're going to freeze…" She commented slowly, not letting go of her katana.

"I'll be fine. I'm training you." Law commented cockily, making his way towards her. He noted the way her eyes always lingered on his abs, usually her lust followed suit.

"M-me? Why does that require you to have your shirt off?" Leila blushed, averting her eyes from him. Law stared into her, silently commanding her to look back to him, to which she couldn't help but oblige. He tensed up his arms as he held up his sword and laid his hat to the side. Leila had to swallow as she felt her breath catch in her throat at his suddenly macho appearance.

Her eyes glazing over his v line and the attractive dark hair that lay just above his trouser line. Law smirked and moved to strike her with his sword, causing her eyes to widen in shock as she quickly moved her red katana to clash against his.

"Don't be getting distracted now…" He growled at her, striking again and again until the two were involved in a full on duel.

"That's why you took your shirt off?" She said, absolutely astounded at his own cockiness. 'He knew I'd be ogling his body and took advantage? This man…'

Law responded with another strike of his sword, cutting a few strands of her hair as he came dangerously close to her neck. Leila's chest was heaving, she was struggling to keep up with Law's stamina and she was trying with all her might against him. She couldn't quite believe how strong this doctor was, she had severely underestimated him.

'I don't know how her abilities work. But if she becomes entranced by a sin can it influence the probability of other sins showing up?' Law theorized in his head. 'I want to run some tests on her, but she's not a guinea pig. This will have to do for now…'

"Why don't you use your full abilities?" Law asked her seriously, continuing his attack. He had thought back to the time the first met, how she showed him her transformation with devil horns and tail in toe. She was holding herself back.

"I-I'm not confident…" She replied out of breath, taking large steps back from him.

"You can't win if you don't"

"Things can go wrong" Leila strongly told him, making a strike against his side to which he grabbed ahold of her wrist strongly. She struggled under his grasp and refused to look into his burning eyes.

'He wants me to use them but what If I lose control?' She thought, utterly petrified at the thought.

"How wrong?" Law challenged, releasing her grip so she could retake her positon in the duel.

Leila didn't answer at first, but she met his gaze with fear in her eyes. "My body's not in good shape. I have less chance of controlling it, you could die, I could die. Everyone could die". Law's crew began to feel slightly rigid and anxious as they heard her serious tone, but they had faith in their captain's choice.

'So her physical health affects it?' Law thought, taking a mental note.

"And what If I say I won't let that happen?" Law tried to reassure her, but she ignored his comments. Law held up his fingers. "Room"

Suddenly the ship was enveloped in a blue bubble, and everyone was under Law's room. Leila looked around cautiously but she looked back to Law who was confident. "Don't worry. I've got you, if you lose control I can stop you no problem"

Leila let out a shaky breath. She didn't know why, but she let herself have faith in Law. She knew he had good intentions, he wanted her to regain control over her abilities – but he just didn't understand. She shook her head in refusal to which Law clicked his fingers, making her float slowly into the air and be transported to hover over the water.

"H-hey…Law" Leila called out to him, frightened. His crew began to protest but Law silenced them with one glance. "Law, I'm a devil fruit user you know?!"

"I don't know. You won't show me" Law protested, making her spine shiver as his cold gaze fell on her.

"S-seriously?" She muttered. Law just stared at her. "Okay! Okay okay, just get me down from here!" Leila called out to him, alarm surrounding in her body. "Please, Law!"

He swiftly moved his fingers so that she fell back onto the deck with a thump and her katana fell out of her hands, leaving blood stains on the deck. She glared at Law with tears beginning to brim in her eyes from the scare but she took a deep breath. She knew what ability would make her win this fight in an instance.

"Law, if you haven't got me, it's over for all of us" She said as her voice trembled. Law nodded affirmatively at her, somewhat excited to find out more about the famous devil fruit.
