Invader Zim ZADR: Chains and Bite Marks (Ch. 3)

I awoke the next morning, body feeling numb from the previous night. . . I sat up slowly, to find myself on the floor where I had blanked out in blissful exhaustion.
I looked around, to find Zim a few feet away, laying on the floor, asleep. I figured his body must’ve blinked out to. . .
I crawled over to him, anger from the previous day completely gone. I examined him, in his dozing state, and what I observed made me sick to my stomach.
Zim’s wrists were badly bruised, most likely because of how recklessly I grabbed them, how tight I held them into place. He was shivering possibly because he had slept on the cold floor all night long. . .
I carefully lifted his head, careful to not wake him, and placed it on my lap. Why had I done that? I’m no better than him, actually compared, mine was worse. . .
I sighed, “Zim? Wake up. . .”
Zim’s eyes opened slowly, then he sat up, pain filled expression on his slender face, “D-Dib?” He seemed to have no fight in him, his old energy gone, replaced with a new mysterious one. . .
“A-are you okay?” I asked worriedly, now feeling worse for allowing myself to do that to him.
He nodded slowly, drawing his knees to his chest.
“I-I’m so, and I mean so, sorry. . .” I choked out, feeling tears coming to my eyes.
I hugged myself, seeing the darkness that had consumed Zim’s eyes since the last time I gazed into their magenta centers. Last time I saw them, they had ruthless lust, they had vanity. . . Now they only held sadness, and something I took to be fear.
Zim stared back, for a long, dreaded silence. Finally he spoke, but it was silent, and more of a whimper, “All will be-” He sighed, “forgiven. . . If you carry Zim, to his room.”
I tilted my head, but did as asked. I picked him up bridal style, then began walking to his room, or at least the one he told me was his own.
When I walked in, I prepared to sit Zim down on the ground, but he whined, “No! Dib-stink my bed!”
I sighed, and did so, placing him carefully on his bed.
Zim released my neck, and laid back on his awaiting bed. He nuzzled into his bed, and then looked up at me pleadingly, “Tuck me in?”
I nodded, and did so, placing the blankets he had, over his body with care. Finally I had to ask, “Why was that your request? When you could have me do something ten times as hard, instead of something you could have always done easily yourself?”
“I couldn’t Dib. . . It- it just. . .” Zim seemed to try.
“It’s just?” I tried to get it out of him, I wanted to help.
Zim had a bright purple covering his face, that I now took to be a blush, “It hurts too much.”
“What hurts?” I asked, not getting it.
Zim looked down at himself and back up at me, that’s when I realized what he meant, “Was I that rough?! I’m so sorry! God, why did I do that?!” I yelled at myself.
Zim seemed to be frightened by the sudden yelling, he jumped, but then seemed to relax, “It’s fine Dib. . . Just forget about it. . .”
“Why have you started calling me Dib?! I don’t deserve that respect!” I yelled, more at myself, than Zim.
That’s when the tears slipped though, and I hunched over onto Zim’s bed, crying.
I felt Zim’s hand, lightly pet my head, and I could hear him trying to calm me. . . Soon enough, his calming voice, with my tears, made my body relive the exhaustion I had the night before, and fell into a deep sleep.
