Deadly Mistakes

Upon the roof of the church, the rain could be heard splattering. It seemed to Serenity that even Mother Earth herself was mourning for Mokuba. Serenity sat in the very front of the church, not daring to look up towards Mokuba's casket, and she had refused to go to the showing. She didn't want to see him dead. This wasn't the way she wanted to remember him. She wanted to remember him alive, and smiling.

"We are gathered here today to grieve the loss of a great friend, Mokuba Kaiba. He was a loving brother, and a great friend," the priest spoke.

A solitary tear escaped Serenity's wet eyes and she felt Joey's hand place itself upon hers. Serenity bit her bottom lip to stop herself from sobbing yet again. Everything was blurry; all she could see was the light flickering of the candles surrounding the casket. It wasn't fair, why Mokuba? He was the nicest person she'd ever met, and he would never have done anything to hurt anyone.

The priest continued to preach and Serenity felt herself getting angry as she clung to Joey's arm. What gave him the right to speak about Mokuba? He didn't even know him, it was stupid. Kaiba should be up there, talking about his brother… but he wasn't even there, not even in the building. He was missing his own brother funeral just because he was work obsessed and didn't want to admit that he was sad.

"And now we ask for the family and friends to come up and speak on behalf of Mokuba…" The priest said, looking around the room, waiting for someone to stand up.

"Go Serenity…" Joey said, shoving her gently.

"I…" Serenity said quietly before obediently getting to her feet, Hikari immediately followed suit and followed her to the front, sitting down beside Serenity's feet as she stood behind the podium, her head hanging. She, Hikari, too knew what had happened, and she grieved for the loss of her master. "I…" Serenity's voice trailed off, she couldn't see, she didn't know what to say. She kept hoping Kaiba would come bursting through the door, wrap his arms around her, comfort her, and help her come up with words to express how she felt. She waited… but he never came, she continued to wait, completely silent, staring at the door through her eyes filled with tears. Then she sighed, giving in to the fact that he wasn't coming. She looked up, wiping her eyes quickly on the back of her hand and sniffing slightly as she began to talk.

"Mokuba was my best friend, my brother. I love him… he did so many things for me… for everyone. He loved life… he loved everyone. I don't think he was ever mean to one person, in his entire life. I say this, because compared to his cold hearted brother who didn't even show up for his funeral… it really shows who the stronger person was. When the Kaiba brothers… were younger their parents died and they were forced to live in a orphanage, where all the had was each other, and then Seto Kaiba challenged a rich man to a game of chess, saying he had to adopt them if he won, which he did. He rescued himself and his little brother from the horrors of living in an orphanage, with two changes of clothes and a cheap education. Together, they over came even the even worse horrors of an abusive father. Seto watched over his younger brother, cared for him, somehow managed to turn him into the caring man he was. They loved each other... they had no one but each other. People used to walk down the street and be able to talk about the Kaiba brothers, of how they'd been through so much together, and how despite Seto's rather mean demeanor, he continued to care for his brother, and only his brother." Serenity knew she was supposed to be talking about happy times, but she couldn't help it.

"And then I came along," she started crying again and Joey quickly rushed to the front. "And I broke them up! I- I didn't mean to I'm so sorry Mokuba!" She collapsed beside the mourning lab. "I'm so sorry! I didn't want it to be like this! Why did you have to leave me here?!" she shrieked, sobbing into Joey's shoulder. "I did this! I'm the reason your stupid brother isn't even here! It's all my fault!"

"No, no shhhhh- it's not your fault Ren," Joey comforted her. "You didn't kill him. You didn't want this to happen." Serenity allowed Joey to help her back to her seat and the priest headed back for the podium but was suddenly stopped by the snapping, growling lab. "Hikari!" Joey snapped. The dog didn't listen. Rather she went back to Mokuba' casket, placing her paws on the edge and looking down at him before raising her muzzle and howling loudly. It was eerie as the dog continued to howl, grieving her lost master. Her best friend, Mokuba had meant too much to everyone.

"Hikari…" Serenity said quietly, sometimes she didn't realize how much she loved him too. Just like everyone else, simply thought of her as some dog that loved everyone. But no, Hikari was going to miss him more than everyone else for a dog was capable of ten times the love any human could have for another being. Serenity picked up the front of her dress and walked over to the dog who was now sitting in front of the casket, her teeth bared at anyone who came within 10 feet of the casket.

"What the hell are you doing?" Joey demanded grabbing her wrist and Serenity continued to walk towards the snarling dog that was now standing, the hair on her back raised.

Serenity twisted her wrist free and continued to walk towards the snarling lab whose tail was between her legs, she kneeled before her, tears still escaping her eyes and wrapped one hand around her muzzle and the other around her neck. Hikari immediately settled down and allowed Serenity to comfort her. Next to Mokuba, Serenity was the closest to Hikari. "Its okay baby, it's okay, I won't let anyone hurt you…"

~*~*~*~*~

Kaiba sat outside the building, headset attached to his ear as he listening to what was going on inside. He couldn't go in though. Especially not after Serenity's little speech and Hikari's loving performance. It was true; he was a heartless bastard who wouldn't even go to his own brother funeral. Everything she said was true, she was always right.

She and Mokuba had deserved each other. Not once had Mokuba ever caused any sort of pain to her, not on purpose, not when he could have easily fixed it. Mokuba was always there, always willing to do everything he had to do to make her happy. Then he, Seto, had come along, and taken them away from each other, causing the only two people he cared for pain. Serenity would have been happier with Mokuba and Mokuba with her. Kaiba could have survived being alone, until Serenity had come along he hadn't really know any different, besides having Mokuba round.

Though as much as Kaiba loved his brother, he had never been the kind of companion Kaiba needed. He had always needed protecting, and caring for. Not often had they ever gone out and just had fun together. Especially not in the last several years… since Serenity had come along. But it wasn't her fault, she didn't ask for them to both fall in love with her. Their conflicts were their own, and mostly Kaiba's fault. Because he was scared Mokuba would steal her back from him. It was his own selfishness and lack of trust that was making him feel as lousy as he was.

Have you ever known anyone that has died, and would have been willing to give up anything and everything to just say one last thing to them? Mokuba and Seto had not parted on good terms. They hardly spoke to each other anymore. They were no longer the loving caring Kaiba brothers. And Seto would give up the world to have that back. He thought of one night before he and Serenity had gotten married, and that she had said to him.

"You shouldn't go to bed with things unsettled Seto," she warned.

"He'll be there in the morning to deal with," Kaiba had said absently, throwing his shirt on the floor.

"This time he might be, but what if someday he isn't Seto? What if one day he isn't there anymore? Won't you regret no having said you were sorry?"

"He'll always be there in the morning; he hasn't got the balls to go anywhere."

"People can't always choose where they go Seto. I really think you should go and settle this now."

"Just forget it Serenity, it really isn't your problem."

He had told her she was wrong, again, just like he always did. But she was always right in the end, this time more than ever. If she chose to accept him again, he would tell her that, and every night, without failing he would tell her he loved her. He would never make that mistake again.

But what had been done had been done and knowing for the next time didn't stop him from regretting it now. Never before had he imagined a life without Mokuba, a life where he wasn't there in the morning to be all happy and always say 'good morning' in a cheerful voice, as if he really meant it. Kaiba's thoughts wandered back to some more of Serenity's wiser words.

"Why is he always so fucking cheerful in the morning?" Kaiba demanded.

"It's a choice Seto," Serenity explained. "Life is full of choices, you can choose to be happy in the morning, or you can choose to be a grouch, Mokuba chooses to be happy, you choose to be a grouch. It's like I said, it's all a choice."

"You can't just choose your mood," Kaiba argued.

"Yes you can. Why are you angry right now Seto? Because Mokuba made you mad last night, right? Now unlike you Mokuba isn't going to allow those bad feeling to carry on to another day, a fresh day where nothing bad has happened yet. You really need to lighten up…"

Kaiba had always felt her little speeches were more like little sermons and she preached the difference between good and bad to him, trying to change him. But never once did she try to change him, she accepted him for exactly who he was, gave little suggestions, but didn't complain if he didn't comply. Simply moved on with life… as if that was her choice. She chose not to be angry about the fact Kaiba wasn't perfect… yet she was still convinced he was.

"Smile," Serenity suggested.

"Why?"

"Because, it makes you more appealing."

"I'm not appealing to you unless I smile?" Kaiba asked, slightly angered by that.

"Oh no, of course you are!" Serenity said, wrapping her arms around his neck and kissing him gently. "You are perfect, and I love you just the way you are."

Why was she so good to him? He didn't have anything for her, except for money perhaps. But he was mean, cold, and lived to work, not love, but yet, knowing all this, she willingly married him.

"Why do you do all this for me?" Kaiba asked as he sat down at the dinner table to his favorite meal, cooked by his two favorite people. "I don't do anything for you guys, I'm not even pleasant."

"We love you just the way you are," Serenity said, placing a plate in front of both Kaiba and Mokuba. "Just having you around is good enough."

Mokuba nodded in agreement, "You do a lot more than you think…" his voice trailed off teasingly.

Kaiba heard the priest announce something about the ceremony being over and he quickly removed the headset and wiped the tears off his face, pressing a button on the door and instructing the driver to take him around the corner so no one could see them.

"Don't you want to wait for Mistress Ser-" the driver began.

"I said drive!" Kaiba yelled and the limo immediately began moving forward and turning around the corner.

Kaiba watched through his window as the people filed out of the church and formed two aisles on either side of the wet sidewalk, wet umbrellas up and awaiting the casket to come out. Kaiba watched, his tears sliding down his cheeks as his brother's casket was carried out of the building, Joey, Tristan, Duke, Yami and Ryou carrying it, Hikari walking slowly beside them. There was supposed to be six people… he was missing. He watched them slide it into the black Hearse and saw Hikari jump into the vehicle as well then looked back at the church and saw Serenity standing on the steps, the rain pouring down upon her small body, and she just watched. As the car drove away, rather then heading for a vehicle like everyone else she turned around and went back into the now deserted church. Kaiba watched as Joey made to follow her but everyone else stopped him, shaking their heads and saying something to him. Joey just nodded picked up his little girl, walking to his own car.

Kaiba waited for everyone to leave before getting out of the limo and walking up to the closed church doors, opening one slowly and entering the building quietly. Serenity sat on the window sill, watching the rain droplets through the clear parts on the stained windows, tears slowly falling down her cheeks. Kaiba didn't know what to say to her. He didn't really want to talk; he just wanted her familiar body in his arms. He wanted something familiar, something to remind him of better times. He wouldn't be at all surprised if she rejected him; actually, he more or less expected it, sort of hoped for it.

Little did he know, she knew he was there, she'd heard him come in, and without even having to see him, she knew it was him. She didn't want to talk to him though. She was too angry, and afraid she'd say something she would regret. So she waited for him to make the first move, doing her best to keep her anger contained long enough to do so. She waited, just staring out the window, her teeth clenched tightly, finger nails digging into the palm of her hand.

When he didn't say anything, she finally chose to speak, keeping her tone as calm as possible. "What do you want?" she demanded, refusing to look at him. When he never spoke she turned to look at him, surprised to see his eyes slightly red. "How could you possible step into this church?" Serenity felt her hardly contained anger escape its cage and rise within her. "How could you possible come into the church after you miss your brother's funeral and even considering speaking to me?" she demanded, her eyes flashing angrily.

Kaiba didn't say anything, he didn't glare at her, nor did he apologize though. Just stood with a sad sort of confused look on his face. Serenity felt small amounts of pity for him. She knew what he was going through wasn't easy. Before she had come along Mokuba was the only person he loved, they'd been through so much together, and now Mokuba was gone. A large chunk of Kaiba's life was gone, his past now seemed empty, completely pointless. He felt his future was lacking meaning as well, what was the point in living without Mokuba?

Serenity suddenly felt bad, why was she just adding to his stress? Why was she adding to his problems? His brother was dead and she was purposely causing him even more pain. But she couldn't help it; he hadn't shown up to Mokuba's funeral and that was hardly forgivable. She slid off the window sill and walked over to him, standing just before him. "I'm… I'm staying at Joey's for awhile…" she allowed her voice to trail off before walking over to the door. She opened it slowly and turned to look at Kaiba who was just staring at the floor in front of him before leaving and closing the door entirely. Tears threatened to pour out of her eyes again as she opened her black umbrella and stepped out into the storm and began walking towards the apartment Joey and Mai shared. It was quite a ways away, but she thought perhaps a good walk would make her feel better, either that or give her a cold and another reason to stay in bed and sleep her life away.

**

Kaiba couldn't stop her. He couldn't bring himself to do anything. She was right, again, of course she was. He had no right coming into the church, being within a 100 meter radius of her either. He'd missed his own brother's funeral; he was like dirt, lower than dirt. Kaiba had now official earned his reputation as a heartless bastard and no amount of flattery or gifts would get him out of this one.

How could his life go from being so perfect to so… horrible? Mokuba was dead, and Serenity had left him… what reason did he have left to live? Even if Serenity ever did come back to him, it wouldn't be the same. He would never be the same. Life just had no meaning left.

With all that decided Kaiba stood up straighter, squared his shoulders and exited the building and walked over to the limo, jumped into the back seat and instructed the driver to take him home. He had something he needed to do, and he had to do it now, before he hurt anyone else.

All his life had been spent hurting other people to benefit himself or his brother. He couldn't stand it anymore. He had to do something about it, he was sick of being, mean and cruel and heartless. And he didn't want to be alone; loneliness was the cause for his bitterness in the first place. He'd rather be dead than have to live through that again.

Kaiba got out of the vehicle as it pulled up in front of his door. He walked slowly over to his door step to get under the shelter of his porch before turning and watching his limo drive away. He looked around his yard sadly. The flowers dance in the breeze as the rain fell lightly upon them. The wind whistled as it played happily in the branches of his cherry trees. Why had he never stopped to admire his beautiful yard before? He paid people thousands of dollars a year to keep his yard nice looking, but he never benefited from it. Why? Why would he do something as stupid as that? It made no sense… like his life… had no real point.

Kaiba blinked back newly formed tears in his eyes and then turned, entering his house. It was a very white house, a huge, bright house. Serenity's feminine touches made it more cheerful than he remembered it as a child. There were pots of flowers every where, and rather than just paintings of abstract pictures, happy things. Dogs, and children, kites, wildlife… why was he such an unhappy person?

Kaiba walked up the long spiral stairs case to the second floor slowly, his hand running along the smooth, white marble railing her remembered Mokuba always sliding down when he was younger. Kaiba recalled giving Mokuba and Serenity crap years ago for sliding down the railing. Only because he hadn't seen the point in it. Fun had never been a word in his vocabulary. Work, work, work, that was his life. But what for? He was rich, he could have retired years ago and died with fortunes to give to his brother's children. But Mokuba would never have children… and neither would he. All of his money would be left for the government to take and spend on lottery tickets. What good was money if it didn't bring happiness?

"I have millions and millions of dollars, what more could a person possible need?" Kaiba demanded to a frowning Serenity as they argued again, as they always did when Mokuba so much as stepped a foot out of the room.

"Money can buy you a good dog, but it can't buy you the wag of its tail," Serenity said cheerfully.

"What is that supposed to mean?" Kaiba asked, sneering slightly.

"Just because you have money doesn't mean you are happy," Serenity informed him. "You of all people should know this because you definitely aren't happy."

"Happiness is overrated," Kaiba stated angrily.

"How would you know?" Serenity demanded. "You've probably never experienced it. Work, work, work, that's all you do. You have a little brother you know, why don't you take him out once in a while?"

Even when Serenity had still been with Mokuba she'd always given him good advice that he had just ignored. She'd always been right… Kaiba would have known this if he paid even the slightest bit of attention to everyone else. If he didn't treat the rest of the world as if they were lower than him. Why was he so stupid? How could he have been stupid enough to lose them both?

"I'll never understand you Kaiba… you've lived a life where you were broke and had no reason to get up in the morning, yet you have no appreciation for what you have, always need more. And you claim that you hate your adoptive father because he was cruel and spiteful, yet you are exactly like him…"

Why was she always right? Kaiba wondered to himself as her headed up the 26 stairs to the third floor, glancing only momentarily at the picture Serenity had hung up, their wedding picture. He wasn't smiling. He never smiled, not even for his own wedding. He was happy, more than happy that day, but he chose to keep his pride rather than please the woman he loved. Why? Why did he always do stupid things like that? Serenity did so much for him, yet he did nothing for her, nothing money couldn't buy anyway. He didn't even smile in their wedding picture…

Kaiba paused, studying a picture of Serenity and Mokuba, long before Kaiba came into the picture. They were both smiling, Mokuba looked much healthier and happier than he had before he died. He really did love Serenity… why had Kaiba interfered? Because he couldn't stand the fact that someone had something better than he had, something he couldn't buy. And he had to have it, for the lone fact that someone else was happy with it, despite that fact it was his own brother and he had always said he would do anything for him.

Kaiba walked up another stair case, leading him to the fourth floor. He glanced at the dent in the wall as he passed it, recalling the time his adoptive father had gotten so angry with him he'd practically thrown him down the stairs. Why was it still there? Why hadn't he gotten it fixed? Because it reminded him of what he was taught, ____(Insert Kaiba's fathers name) would hit him, over and over until he did not so much as flinch. He needed it, for his image. "No one would take a smiling man seriously, or listen to a happy go lucky fucker", were his exact words.

Sighing Kaiba continued to walk up the stairs, taking in every image, every memory. Trying to answer the questions he never even cared about before, that he never would have even considered asking himself before any of this had happened. He'd walked down these hallways millions of times over his years in the house… but he'd never actually acknowledged it. Never realized how lucky he was.

"You never really know what you got until it isn't there anymore," Serenity said in a as a matter of fact tone.

"What is with you and all your bloody quotes?" Kaiba demanded angrily.

"They aren't quotes unless people use them, and people won't use them if they aren't true…" Serenity replied, outsmarting him once again.

In all of his memories with her, he was always mad, and she was always happy… why was this? Because she's a happy person and I'm not… just like she always told me Kaiba thought to himself. Just like Mokuba, they were both happy people, but I never was. As Kaiba thought back on his life he realized how much he regretted and what he truly wished he had done differently, which was almost everything.

Kaiba climbed the last staircase, the one to the fifth floor and then entered the room he normally shared with Serenity. Grabbing onto the door handle he looked down at it, rubbing it gently with his thumb before turning it slowly and pushing to door open. He felt like he hadn't been in there for years, yet it had only been several days. It was all so… unfamiliar. The entire house seemed different now, without Mokuba terrorizing the building with his happy comments and cheerful attitude, which as of late had been almost entirely fake.

For the first while, Mokuba had really seemed to be okay with it, there were some awkward moments between him and Serenity, but over all, okay with it. Then slowly he deteriorate, sleeping less, working more, almost never doing anything fun. It was work, work, work, weather he be running for 3 hours or doing paper work. He constantly needed his mind to be occupied doing something. He generally turned into a nicer version of Kaiba.

Kaiba slowly walked over to the other side of the room. Slipping his black coat off as he went, loosening the buckles on her arms and sliding his shirt over his head and then wandering into his bathroom. He studied himself in the mirror, there were huge bags beneath his eyes, he was pale and he was missing the usual… spark that was usually there. No, life was worthless.

Kaiba glanced down at the razor on the sink. And then walked over to the shower and turned it on. Kaiba unzipped his pants, dropping them to the floor, grabbing his razor and climbed into the shower. He allowed the steaming water to run all over his body before he opened his eyes once more and looked at the razor in his hand. Raising both hands, Kaiba gripped the razor, holding it diagonally against his wrist, shutting his eyes and reminding himself that he wasn't worth anything anymore, before clenching his teeth and slicing quickly. Once, twice, three times. Kaiba looked down at his wrist, the blood was pouring out. He had no idea how long this was supposed to take, but it was painful, just how he deserved to die. Kaiba did the same to the other wrist.

Blood was staining the water by his feet it was like a river of red food color stained water, but this wasn't like some gag blood meant to scare little children. This was the real thing, when he was bled out it would be all over with. No more looking around and feeling stabbing pains because of all he had done, or more painful, all he HADN'T done. He winced slightly as he moved, Kaiba awaited the life to poor out of his cruel, useless body. It was taking so long and watching this all happen was hurting him even more. He just wanted it to all end in the blink of an eye.

He ground his teeth, getting frustrated, annoyed with how long this process was taking. He was used to wanting something and having it within the minute. He looked at the razor and looked back at his wrist. He raised the razor up again and began to hack at his wrist again, he cut up and down his arm. There was a sort of crazed look on his face. Over! It'll soon be over!! He put the razor in the hand and began hacking at his other wrist and arm.

He looked down at the now even redder water that flowed around him. He tilted his face up and let the water run down it. He tilted his head back down and opened his eyes.

He felt his grip faltering on the razor, he tried to grasp it firmer but the blood and water made it slip from his hand. Looking down at the razor he tried to decide if it was really worth, but holding up his arms to look at them…he found that they weren't clear in his eyes. His sight was blurry, he tried to bring his arms closer but they felt too heavy, they dropped to his side and his eyes lazily looked around dazed and confused. I'm…dying…

Seto Kaiba's hand instinctively tried to grab onto the shower curtain to keep himself from falling but he didn't have enough strength nor presence of mind to perform that action. His body fell back into the tub. His no longer sparkling blue eyes rolled up into his head and he lost consciousness.
