Thanks a bunch for the reviews. ^___^

Because I'm lazy, the disclaimer in the first chapter applies to all chapters. Bonus points and Yuugiou love to you if you know where I'm getting my chapter titles from.

I'm trying to keep Seto like Seto for as long as I can help it. He's so much more fun to write as a cynical bastard. Alas, character development always finds it way…

This chapter takes place about maybe a week or so after the first one, and Seto's had his CT scan, but not the results...

Unseen Angels

Sonata

(Dr. Housou's Narrative)

I've stared at the results from the scan at least twenty times in the last hour.

I still can't summon the nerve to call him.

My hands tremble over the phone, as I sit down in my chair.

Kazuza stuck a Post-It on top of my computer which has been haunting me all day. At first, it was just whispering for me to call, but now it's screaming.

I sigh, and pick up the receiver. My fingers, now getting sweaty, slide over the numbers.

I wait. Someone picks up after two rings.

"Hello, Kaiba Corporation. How may I help you?" A young lady answers the phone, and I completely forget why I'm calling.

There's silence, and it snaps back to me.

"Oh, hello. This is Dr. Housou. May I speak to Seto Kaiba?"

"One minute, I'll see if he's busy."

She puts me on hold, and the music is somewhere between somber and depressing.

Then again, that's Seto Kaiba for you. I haven't even known him for that long, and I'm saying that. Imagine what people who really know him think.

"Dr. Housou? Kaiba-kun will speak with you now." There's a little static, and his voice comes in, sounding deeper than usual on the phone.

"Yes?"

(Change of Narrative - Mokuba)

My brother is talking to someone on the phone. I can tell it's not another businessman, because he doesn't have that set glare on that people can feel down the phone.

"Yes, yes…I see. Okay. No, no, it's not your fault."

God, it must be bad. My Nisama is consoling someone?

"Okay. I'll be down there tomorrow. Thanks. Bye." His voice sounds strained, and I think he's holding back a cough.

He only proves me right when he winces, and looks at me. He looks as though he's about to say something, when;

That's right. The cough that was bouncing around in his lungs escapes, and he's into the third box of tissues in a week.

When he's done, I stare at him. He stares back evenly, and I loose.

I'm the first to look away. It's a game we play when we have nothing better to do.

He smirks, but this quickly disappears, as if he just remembered something.

"Mokuba. I…I'm very sick." I stare at him again.

"What? What is it? Is it pneumonia, like Dr. Umeki said?" He runs a hand through his hair, an almost uncomfortable look on his face.

"No, Mokuba. Worse than that. They think it's lung cancer."

I must have a horrified look on my face, because my Nisama stands up and walks over to me. He kneels down to my height, and I stare at him. Right into his deep blue eyes, which is something I've never done before.

I don't see the Kaiba that yells at someone over the phone at least once a day. I don't see the Kaiba-kun that's more worried about Duel Monsters and deadlines than his own life. I don't see the Seto Kaiba who tells Yugi Motou every day that magic doesn't exist.

I see my Nisama, as plain as he'll ever be. My Nisama, who only has the last hope, faith and trust in magic. It's dying fast.

You can't take my Nisama away from me!

"It's not fair…" I whisper, and the strangest smile I've ever seen passes across his lips. He puts his hands on my shoulders, and looks at me seriously, as if he was talking to someone his own age.

"Please, Mokuba, if I do die, you have to promise me one thing."

"What, Nisama?"

"Don't cry for me. I'm not worth it."

I take a step back, and he looks down at the floor, still at my height.

How can he say that? He's all I've got left! He's being so selfish!

I run out of his office, out of the building, down the street, out of sight of Kaiba Corporation's main building..

I just need to run, as if I have all of the energy in the world. If I run, everything's going to get better, and everything that's tried to hurt me, that my Nisama protected me from, will disappear, like it never even existed.

I'm staring at the pavement, trying to laser it away.

This isn't fair!

"Ah! Mokuba?" I slow down, and realize Yugi Motou is now behind me, he must of turned onto this street from an alleyway. I turn my head, and his expression deepens into a concerned one.

I'm walking now, and this change of pace breaks me. I stand still, and Yugi catches up with me.

"Mokuba? Mokuba, what's wrong?" I stare at the ground, and try to choke out words, but they're being held in my throat.

"Nisama…" Is all I can manage. Yugi pauses.

"Look at me, Mokuba." His voice is soft, but it sounds much more dangerous than it used to.

I continue to stare at the sidewalk. I don't want to look at him.

"Mokuba!" His voice sends a chill up my spine, and my head snaps up to meet Yugi's, who looks just as surprised as me.

Whoever just talked to me definitely wasn't the Yugi Motou I knew.

"Sorry." I barely catch this whisper, and Yugi continues with his interrogation.

"Mokuba, please, tell me what's wrong." That pyramid puzzle around his neck stares at me with one, big, questioning eye.

"My Nisama, he's really sick," I almost sob. "He's got cancer." Yugi gasped, and wrapped his arms around me, pulling me into a hug.

"I'm so sorry."

This apology isn't the kind you hear from people who feel that they're supposed to say something. This is the kind of apology that makes you realize there is such a thing as deep sorrow that can tear away at you.

I start to realize that my Nisama meant more to Yugi than any of us ever knew. Not in the way that Jounouchi, Anzu or Honda mean to him, but in a different way. I'm not sure how to explain it.

My Nisama was always there, to stand before Yugi and tell him to wake up, to stop dreaming, to face reality.

I think my Nisama is the one still trapped in nightmares.

Yugi tugs on my sleeve, and motions back in the direction of the Kaiba Corp. building.

I can only nod slowly, and Yugi smiles.

We start to walk back to where all of my problems are waiting.

(Change of Narrative - Yugi)

Mokuba is so, I don't know. So much like Kaiba-kun, but somehow much more different.

We arrive back at Kaiba-kun's main building, and the receptionist lets us in.

Mokuba doesn't seem to know what to do from here. He stands by the elevator, his finger hovering over the button. When he finally presses it, it's like he just made a life-changing decision.

I open the door to Kaiba-kun's office slowly, but he doesn't even look up when I step in, Mokuba at my heels.

"Kaiba-kun?" I venture further into his office, but he keeps his head down.

"Nisama? Nisama, I'm sorry-"

"Just go." His voice is cold and harsh, as usual. Mokuba takes a step back, but I grab his arm, and shake my head. I'm not going to be threatened by Kaiba-kun. Not this time.

"Kaiba-kun, please, tell me-"

I gasp when he stands up, slamming his hands down on the desk.

"If there's anything you can do for me? Unless you can stop death, Motou, I doubt it." He growls, his hair hiding his eyes.

"Nisama." Mokuba mutters behind me, his voice thick, on the verge of tears. "I'm sorry, Yugi." He says quickly. I just nod.

I've been fighting with mou hitori no boku this entire time, he's been 'irked', to say it lightly. Just when I'm about to leave, I can feel the Puzzle tremble. My 'darkness' floods my mind, and I stop right in front of the door, my hand retreating from the doorknob.

He twirls around on his heel, eyes flaring up.

"Kaiba!" He growls, marching back up to the desk. I'm in the back of my mind, begging him not to do anything rash.

Seto Kaiba, who has just sat back down, looks up at him as if he's bored, and has nothing better to do.

This just fuels his fire.

"Yugi was just trying to help! Have you no compassion?!" He yells, and by the glint in Seto's eye, I can tell he caught mou hitori no boku's mistake.

He called me Yugi. I sigh, but Kaiba's eyes suddenly widen.

Two hands clamp around his mouth, and he closes his eyes as he starts to cough. Mokuba rushes up to him, hovering like a worried mother.

----

(Change of Narrative - Yami Yugi)

Kaiba's eyes open as he coughs, and he stares at me. It's unnerving, because as his chest heaves, and his body shakes, that cold and threatening blue gaze never falters.

Two can play at that game. I stare back, and I can see dark laughter passing through his eyes. Even though this is replaced by pain from coughing so long and hard, he starts to become blurry, I've been staring at him for too long.

When he stops coughing, we're both still staring at each other.

I dare Kaiba to look down at his hands, which are now flecked with red in the corner of my vision. He dares me to look away, and loose at his own game. Which I can't let happen.

Mokuba notices, and smiles, because at the moment, everything is all right. His brother isn't just going to die, because his brother simply can't. I don't fully believe him myself.

Yugi finally summons the power to regain control, and when he realizes I've been staring at Kaiba, he blushes and looks away. I curse in the abyss that is my Aibou's mind, and Kaiba smirks.

Damn it. I hate when I loose.

End of Chapter Notes: We'll be giving Seto a diagnosis next chapter, courtesy of Dr. Housou and Dr. Umeki. *both doctors wave*

"Mou hitori no boku" means "the other me", usually used to refer to Yami Yugi.

I intentionally portrayed Yami Yugi as a young man who doesn't care about the fine details, he still sees Seto Kaiba as he always has, and doesn't fully grasp the finality of death, perhaps because he's avoided it for so long. A bit like an adult, a bit like a child. *pats Yami Yugi*
