The next day was Kaiba's day off, and he had planned it meticulously. He started it at Ten in the morning. He got up at nine, worked out, showered, and dressed, and then got Mokuba up. He changed him, bathed him, helped him dress, and then led him downstairs to eat breakfast. After a breakfast of eggs, toast, pancakes, and sausage, Seto took his son to the park to play. When he felt Mokuba had burned some energy off, they went to Kaibaland and went on some of the rides there. When lunchtime rolled around, Kaiba took Mokuba to a private room to talk and eat. After they were served their food and left completely alone, Kaiba spoke up.

"Are you having a fun day?" He asked. Mokuba nodded happily.

"Yeah! So is Spike!" He said, pulling his beloved dragon a little closer.

"Is he?

"Uh huh!"

Kaiba smiled at his enthusiasm, but then grew more serious. "Can I ask you both something?"

Mokuba nodded, picking up on the subtle change in his Daddy's tone.

"What do you and Spike think of Kisara?"

Mokuba's fork paused in midair, some of his noodles falling off. Kaiba wasn't sure how to take that. It was a moment or two before he spoke.

"I dunno." He shrugged, indifferently.

"Would you want her to spend more time around us?" He figured it best to get the big question out of the way now. Mokuba stared at him, not in surprise, but something else.

"Well... she's really pretty and she seems nice." The words were said hesitantly. Seto could see that something was troubling his child. "I guess so... But..."

"But what?" Seto asked, concerned. Mokuba mumbled something to himself. Seto went over to him and tucked a lock of hair behind his ear. "Mokie, what's going on with you?" He asked as gently as he could manage.

"Well... I guess I'm just scared."

"Scared? Of what?"

I'm scared that you won't love me anymore. He thought the words, but they wouldn't come out. He shook his head, clamming up.

"Mokuba... What are you afraid of? You need to tell me what it is so I'll know how to deal with it." When Mokuba finally did look up to him, it was with teary eyes.

"I don't want you to forget about me." He croaked. "I don't want you to not love me anymore because you have someone else... I don't want you to replace me..." The words were meekly said, but full of sincerity. Seto automatically flinched away from the words as if they were objects poised to hurt him. The action was enough to break Mokuba's walls, and suddenly he sobbing desperately, his fears finally out in the light. For a second or two Seto was too stunned to react before his instincts kicked in. He pulled his son into a fierce embrace, cuddling him and rocking him back and forth as soothingly as he could manage.

"It's okay." He whispered, rubbing circles on his back. "Oh Mokie... I'm so sorry."

The words stopped his sobbing and rendered him completely motionless as he looked up at his Daddy in confusion.

"W-What?"

"Mokuba, I would never ever replace you. There's no one who could ever take your place. Nobody could make me smile like you do. No one could make me laugh the way you do. No one could make me proud the way you do. There's only room for one baby boy in my heart, and you're it." He promised.

"But what about Kisara?"

"Just because I met someone doesn't mean they can replace you. I would never go along with this without your blessing. You are the most important thing in my life, and I will always put you first."

Mokuba smiled brightly at him and threw his arms around his neck.

"I love you, Daddy." He said, holding him tightly.

"I love you too, buddy." He said, quietly. When the hug ended, Seto looked up at his son and put his hands on his shoulders.

"So, are you really okay with her coming around more often?"

Mokuba nodded, his fears relieved.

"You're sure?" He nodded again. If she made his Daddy happy, he would deal with it. Then, Mokuba came up with a brilliant idea.

"How about we invite her here to spend the day with us?"

Seto blinked, and then grinned. "That's a wonderful idea. Are you sure you want to do that, though."

Mokuba nodded. "I'm sure."

Kaiba ruffled his hair affectionately and then got out his cell phone to give Kisara a call. She said she would be there in an hour after her meeting ended.

When she did arrive, she immediately got on board with their plan. She was introduced to Spike, and happily shook his claw. It seemed childish for Mokuba to still have a toy and be so attached to it, but she didn't mind. Watching the dynamic between them, Kisara could see the closeness that bordered on father and son. They loved each other deeply, that was clear. It wasn't hard for her to make herself fit into their dynamic. It was natural, although she felt unsure if they felt the same way. She tried to escape her uncertainty and get inside of their heads, but couldn't seem to. So eventually, she stopped trying to figure them out and just let things happen the way they were meant to. It was Mokuba whom she hoped to impress today. She knew that nothing more would happen between her and Seto without his say, so she desperately tried to win his approval. But the more she learned about him, the less she tried. He was a sweet boy who was easy to care about. By the day's end, she felt like they were friends, and Mokuba seemed to feel the same way. She wasn't surprised when they asked her to come over to their home for dinner, nor when he asked to say goodnight to his son when the hour grew late.

The only thing that did surprise her was when he opened what was supposedly Mokuba's bedroom, and saw a nursery instead.
