A/N: I was debating whether I wanted to make these two chapters into two separate fanfics, but… yeah. You know. It's better to do it as one. Anyway, this is Link's thoughts on Dark Link's death.
The Death of the Dark Twin
Who is this man I've just killed? Why does it feel like I've killed a portion of my own soul by killing him?
Tears prickled underneath my eyelids, and I blinked them back. I didn't want Navi to see me cry. Why does it hurt so badly to see this… this monster dead, his purple-black blood staining the water around him? Why does it feel like I've just killed my best friend?
I knelt by the body of Dark Link, the sub boss I had just killed. I hadn't even bothered to clean his drying black blood off of my hands or my sword, regardless of how meticulously I normally cleaned the Master Sword. I can't even understand why I'm crying. He would have killed me without a second thought; I know he would have, because that's how bosses work…
I heard Navi calling for me to come, but I couldn't just yet. I reached down and stroked the monster's cheek, running my hand over the features which were exactly like mine except for the color of his skin. His hair, his skin, his lips all felt like my own. The same tunic, the same boots, the same weapons. The same body…
For some reason, a thought occurred to me: Who will mourn his death?
I have Saria, I have Ruto, I have Darunia, I have all my friends, all the people I can count on and who count on me. But was there anyone who loved my black twin? Was there anyone who was counting on him for something?
I didn't want to think about this. If I started thinking about these monsters, how could I ever awaken all the Sages and defeat Gannondorf? I can't crack now, I've come too far and accomplished too much…
Miserably, I dissolved into tears, sobbing like some little kid who had lost his favorite toy. Why, oh why, oh why was I crying over the monster I had just killed! But I couldn't control myself, despite how stupid my weeping seemed and how much I tried to control it.
Navi flitted up next to me, making an alarmed ringing sound. She cried out to know it I was okay, and what was wrong, but I barely heard her, and even if I had I couldn't have answered her.
I don't know how long I cried. It might have been a minute, it might have been an hour. I can't remember, and I really don't care. All the while I held the body of the fallen monster against my own, trying desperately to figure out why this was hurting me so badly.
Navi eventually stopped me, flitting directly in front of my face and striking me between my eyes. She demanded that I get up, that I continue with my quest, and why was I crying, damn you! I didn't answer her, but I did at least stand up and curb my tears.
I never did tell Navi why I was so upset, and that was mostly because I never figured it out myself.
I had wanted to bury the body, but Navi, in one of her fits of frustrated rage, demanded that I stop wasting time and acting like a baby, and get on with the quest already.
With one last look at the corpse of my slain enemy, I walked toward the door. No matter what I did, the feeling that I was incomplete never left me.
