Chibigal4: Alright, I'm done being lazy, and I'm posting the third and final chapter. I know you want to know what happens (otherwise, why would you be reading CH 3?) unless you're dying of boredom, but in that case, you probably don't really mind my endless ranting of absolutely nothing…Ok, I'm done.

Disclaimer: I don't own Yu-Gi-Oh, but I watch and/or think about it religiously, every day.

Ch.3: Unexpected

Kaiba sat back in his chair and stared at his screen, almost not believing the words there. 'How can the boy I've known, looked out for, and loved for 11 years not be my biological brother?'

He was brought out of his thoughts by the doctor tapping him on the shoulder. "Mr. Kaiba." Kaiba said nothing, but stared at the doctor. "I have wonderful news…Two hours after we found what was wrong with your bother, an organ donor with O type blood, donated one of their kidneys. The operation is over, and your brother is out of intensive care. He's in a private room sleeping. You may go see him and spend as much time with him as you want."

Kaiba looked at the clock and saw it was 8:03 a.m. Kaiba stood up, taking his briefcase and laptop with him, and followed the doctor to Mokuba's room. The doctor shut the door behind Kaiba, leaving the two alone. Kaiba walked up to Mokuba's bed and sat in the chair that was right next to him. He set his briefcase on the floor and his laptop on his lap, with the screen facing away from Mokuba.

Mokuba slowly opened his eyes. "Seto."

"Mokuba, there's something I have to tell you." Kaiba said, taking Mokuba's left hand, which hand no birth mark, and looked right into his blue eyes. "You know…If you ever need me, I'll be right there beside you. No matter what happens, you'll always be my little brother, and I'll always love and protect you kiddo."

Mokuba smiled and said. "I know big brother. I'll always be there for you too." He yawned. "Seto, I'm tired."

"Then take a nap." Kaiba advised. Mokuba shut his eyes, and fell asleep, still holding his brother's hand. Kaiba, using his other hand, looked at the screen. 'I have in front of me the only proof that this boy is not my brother, but I'll fix that…' With one hand, he changed a few things, and saved the modified file. He smiled to himself, and looked over at Mokuba. One thing still bothered him. He wanted to know who the donor was, and luckily for him, he knew how to do it. Just as easily as he found Mokuba's file, Kaiba was able to hack once again into the computer's data base to find the donor. He found the right time, right blood type, and organ, and then looked at the name. "How in the hell?..."

Down a few halls, a door closed. "Is it safe now?" a voice whispered.

"Yeah," came the answer from a boy lying on the bed.

From where he was standing by the door, he materialized to the point where he could be seen. Yami, the spirit of the Millennium Puzzle waked over to the bed, and sat on the edge. "You've done a wonderful thing…Because of your selflessness; you've made it possible for another to live longer. I'm very proud of you, Yugi."

The End

Chibigal4: How's that for an ending?...Yugi was the one who saved Mokuba! And they all lived happily ever after…But Kaiba still doesn't like Yugi. Why?...I don't know…he just doesn't…It's because…he's Kaiba…Ok, R+R and flames will just…be ignored, because I can't think of anything else to do with them right now. It was brought to my attention that this could've ended in an angst way without the death of Mokuba, so I've decided to write an alternative ending. I'll post it up as a 'new' story. So, for those of you who wanted a happy ending, you got it, and for those who wanted angst, keep your pants on, I'm working on it. Keep your eyes open for Loved Through Thick and Thin: Alternative Ending, coming soon to a computer screen in front of your face.
