Summary: While searching through his mother's items, Mokuba uncovers something that could hold more answers to her past. However, Kaiba steps in and gives him some orders regarding his search.

Thanks for the reviews everyone. Sorry for the long wait, I've had a lot going on with school and trying to update my other stories. Word of advice: never create more than one 'in-progress' story at a time. Anyways, read, and enjoy.

Mokuba laid on the couch, mindlessly watching TV was he waited for his brother to return. He flipped through the channels until he came across a talk show. He lowered his arm and stared in curiosity.

"Alright Bill, the results are in," said the host as he opened up an envelope, "when it comes to three year old Gerald…you are the father!"

The man and woman on the stage began cursing colorfully as the audience made a loud roar. Disgusted, Mokuba turned off the TV and threw the remote off to the side.

"I hope Seto's meeting went better than that," he muttered to himself.

Several seconds later, the front door opened, revealing a very irritated Kaiba. He slammed the door shut, causing a picture to fall off the wall, and marched over to the couch. He sat down and looked over at Mokuba with a strange look on his face. Mokuba knew this wasn't good.

The awkward silence was broken by the sound of the doorbell ringing. Mokuba sat up to answer it, but Kaiba had already gotten out of his seat and marched to the door. He opened the door, and saw Pegasus standing near the entrance way with a look of triumph.

"Well hello-"

Kaiba cut him off by slamming the door in his face. Kaiba turned to walk away, but Pegasus opened the door and barged inside.

"Honestly," Pegasus scolded, "is that any way to treat family?"

"GET OUT!" Kaiba yelled, clenching his fists.

Mokuba flinched and huddled up on the couch. Pegasus stopped walking, and crossed his arms.

"What are you going to do?" he asked daringly, "call the cops on me?"

"Don't try me!" Kaiba yelled again.

"Well, we'll just see what DHS has to say about that."

Mokuba and Kaiba both looked very confused. Kaiba growled as Pegasus continued to smirk.

"And what is that supposed to mean?" Kaiba demanded.

"Oh Seto," he replied, shaking his head, "you've gotten so caught up in your work that you've forgotten that you're only a child. How tragic."

"Seto," Mokuba asked with a look of worry, "what is he talking about?"

"Guess I have to spell it out for you, huh?" Pegasus answered, "your brother is still a minor; therefore, he is my responsibility. Once I update the paternity papers through the court system, you and your brother will live with me!"

"The hell we will!" Kaiba fumed, "I'll sue for emancipation!"

Pegasus failed to suppress a chuckle, "okay then. But until that time comes, you won't have a say in the matter."

"And in the meantime, you can leave!"

Kaiba opened the front door and literally pushed Pegasus out of the house. He then slammed the door and locked it shut. Kaiba turned and walked upstairs; stomping the entire way. Mokuba could hear Pegasus getting back into his vehicle. He sighed, and decided to up to his room.

Mokuba laid on his bed, looking through the bag of inheritances that their mother had left behind. Among them were Egyptian artifacts; such as jewelry and bits of pottery, but also something else. Mokuba reached into the very bottom on the bag and pulled out a book.

Confused, he looked at it closer, and noticed it had a small lock on the side, which had been partially broken off. His eyes widened as he realized what it was.

"Mom's diary," he breathed.

He excitedly tore the remaining lock off with his hands, and flipped through the pages. He frowned; for he realized that everything was written in Arabic.

"Duh," he muttered to himself, "what did I expect?"

He gently placed the book aside and rubbed his temples. The whole situation with Pegasus, his dead parents, and his brother was really starting to get to him. Then, something hit him-he had never gotten information about his dad.

"Oh man!" Mokuba muttered to himself, "how could I forget?"

Mokuba reached for the phone book, but hesitated. The last time he had hired a private investigator, it had led them directly to Pegasus. He didn't know if he was willing to risk having more trouble on his plate. But still, he wanted to know. Mokuba sighed, wishing that there was an easier, safer solution. Then, a thought hit him.

He sat up and reached for his cell phone. He quickly dialed a number, and within seconds, someone answered.

"Yes master Mokuba?" Roland answered.

"Hey Roland," he said as he stretched out on the bed, "I got two special jobs for you. One: I need you to take this book I found and have it translated."

There was a pause, then Roland answered, "yes sir."

"Two: I need you to find out everything about Hideki Isamu."

"Isamu?" Roland asked, "what happens if I come across more than one?"

"Well," Mokuba said, "tell me about them too. In fact, get some info on all the Isamus around here. That's all."

"Yes sir," Roland said, "would you like me to retrieve the book now?"

"Yes please."

"Alright master Mokuba, I will be there soon."

Mokuba hung up the phone and sat up. At least now he would have some distraction from the current ordeal.

Kaiba sat in his office with the shades down and the lights dimmed. He sat in front of his laptop as he rubbed his temples. He had thought back to the chat he and Pegasus had in the clinic.

"Now Seto," Pegasus said with a smirk, "or should I call you son? Which would you prefer?"

Pegasus turned to face Kaiba, who was still slouching in his chair with his head facing the ground.

"I'd prefer that you didn't speak to me!" Kaiba snapped, without turning to face him.

Pegasus frowned. Kaiba then took both hands and covered his face, making grunting noises under his breath.

"I for one think we should form a new company. Let's combine Industrial Illusions and Kaiba Corp.; what do you say?"

This time, Kaiba brought his head up and glared at him.

"I say; you can do that over my dead body!" he yelled.

Before Pegasus could say anymore, Kaiba stood up out of his seat and marched out of the clinic. Pegasus ran after him as he got into his limo.

"SETO!" he yelled angrily.

Kaiba's limo took off, leaving Pegasus behind in the dust. He then looked at his limo, and decided to follow him to his mansion.

"Ugh," he grunted as he stared at the screen, "no way would I ever merge Kaiba Corp. with that snake's company!"

He then placed his hand back on the mouse and preceded working.

"Although," he muttered to himself, "he will prove to be a valuable asset. If I want my plan to work, I will simply have to go by this another way."

Then, he heard a knock at the door. He looked up with suspicion.

"Who is it?" he yelled.

The door opened as Mokuba walked into the office. Kaiba sighed with relief.

"Oh, it's just you. What is it?"

"Roland's going to be here soon to pick up mom's diary," Mokuba explained. Kaiba looked at him closer and noticed he was holding a book, "I'm going to take a shower, so I want you to make sure he gets this."

"No," Kaiba said.

"Huh?" Mokuba asked, not sure if he'd heard right.

Kaiba sighed and stood up, "Mokuba, your curiosity has gotten us into a deep enough hole as it is. I know you might think I'm being unfair, but enough is enough. I want you to drop this whole thing. No more searching, and no more questions. Got it?"

Mokuba stared at his brother, who was now crossing his arms and giving him a stern look.

"Mokuba," he said sternly and impatiently.

Mokuba frowned and turned slightly away from his brother.

"Come on Seto, we already know the truth about your, well... I mean, what more harm could a little more searching do?"

"What more? What more?" Kaiba began to raise his voice, "You have no idea what skeletons our parents could've had in their closets. We've had nothing but problems ever since they came back into our lives!"

Kaiba sighed and sat back into his seat. Mokuba began to think that maybe he was right.

"Give me the diary," Kaiba ordered.

"Huh?" Mokuba asked.

Kaiba was now leaning forward, with his arm reaching out to Mokuba. He sighed and looked at the book, and looked back at Kaiba. He handed the book over.

"What are you going to do with it?" he asked.

"Lock it up," Kaiba answered, "someplace where you or anyone else can't get to it."

Mokuba gasped as Kaiba tossed the book carelessly into one of his desk drawers.

"Call Roland," Kaiba ordered, "tell him not to come."

Mokuba nodded, and left the office. He walked over to his room when he heard the doorbell ring. Before he could react, the door to his brother's office opened. Kaiba left his cave and headed towards the stairs.

"Don't worry about it," he said to Mokuba, "I'll deal with this."

Mokuba stood by and watched as his brother ran down the steps and opened the front door. Roland stepped into the living room with an umbrella in his hand.

"Good evening sir," he said to Kaiba, "I'm here to pick something up from-"

"That will no longer be necessary," Kaiba said, "the book is now in my possession. You can go home."

"Yes sir," Roland said as he reached for the doorknob.

"Oh, and Roland," Kaiba added, "if Mokuba asks you to do anymore of these little investigations; don't do it. If I find out that you do, you can find another job!"

Mokuba gasped. Roland stared dumbfounded at his boss. He swallowed hard, and nodded.

"Yes sir Mr. Kaiba," he said as he opened the door.

"You can leave now," Kaiba hissed.

Roland walked outside and reopened his umbrella. Kaiba slammed the front door shut behind him. Mokuba stumbled back to his room, not knowing what to do next.

A/N: Oh Kaiba, always gotta spoil the fun don't you? He's just too protective sometimes, isn't he? As far as his 'plan' goes, you will find out more about that later. Well, tell me what you think about this chapter and the story so far.
