(Quick A/N-  I did my homework, and the picture above explains exactly what Vikk's got... It's sad, but true. It's what I based the symptoms off of...)
-Sky's POV-
Somewhere around midnight, I wake up to hear my name being called. It's Vikk, and it sounds bad. As I open my eyes to face him, I see him holding his chest, where his lungs and heart are. He's gasping for air, and his face is full of pain. "S-Sky..."
I throw myself to my feet, and carry him to the living room. "Ty. Help me. NOW." Ty leaps off the couch, and takes hold of Vikk while I get his meds. "What happened?!" "I don't know! He woke me as I asked, and this is what I found!"
"Vikk," I call from the bathroom, "Take the deepest breath you can and let it out slowly. Just breathe, bud. Slow and deep. Okay?" I can hear him mutter, "O- okay." I go back out to find him still in Ty's arms, and he seems to have gotten passed the breathing issue. But his face was still pure pain, and his hand had not left his chest. It still hurts him.
I hand him the pills in his open hand, and get the same glass as earlier and refill it. He takes the pills, but I can see his body relaxing. The knowledge of closing in relief helped him settle a bit. As his body slowly processes the scene around it, Vikk gets jumpy, which is bad for his wounds. He jumps, and I see instant regret in his face.
Ty holds onto the scrambling, regretful Vikk as he tries to pull himself away from Ty. Ty loses his grip, and Vikk starts to fall. I catch him with inches to spare, and pull him close to me. I hold my hand over the back of his head to help him relax just a bit more. Vikk hugs my neck and starts to shake.
"Bud- you okay?" "N-o." "What's the matter, Vikk?" "My- head. It hurts bad. My back- it hurts bad too. My legs hurt too." Okay... so... his heart has slowed down to a normal pace, so he's doing better than before.
I watch as Ty comes into the room again, and Vikk moves away from him. "Is there an issue, Vikk? Why are you backing away?" "That's n-not hi-him." Ty gets serious, and angry. "What do you mean? I'm me." "N-no. You- you aren't Ty." "How isn't he Ty, Vikk? You don't just say something like that without explaining yourself."
He looks at me desperately. "It- doesn't feel like- Ty. It feels- bad. He's- bad. Not real." Ty looks angry, and he also looks confused. "What?" "You. Are. Not. TY. I swear, to Notch. Please Sky. It'snotTyI'mtellingyou. Please!"
I have to believe one side or the other, and I'm going with Vikk. Ty's behavior is- off. It doesn't seem like Ty to be so angry at something so small like this. "Vikk, I believe you." I turn to 'Ty', "You aren't Ty. Where is he, Dad?"
Ty disappears, and my dad takes his place. "Smart kid. That's why you can't survive tonight. I wish I could kill you Sky, but I sadly can't." I summon my sword, and press the tip to my dad's sternum. "Don't come any closer. Or I will press hard enough to injure you permanently." He knew I could, and I would if he did come closer.
He knew he had no business here, and I knew this was my consequences come back to bite me in the ass. My dad slipped his hand behind his back, and I saw the glinting edge of his sword. He swung at my head, and I moved swiftly and pulled my sword up with inches of clearance above my head. "I'll repeat myself. Where. Is. Ty?" He just snarls at me and pulls his sword off of mine.
I can see Vikk out of the corner of my eye, and I see he's somehow gotten out of the chair. He is now sitting in the corner of the room, watching the fight from a safe distance. "The Ender is at the castle, drugged and chained. I do not know where the other is, before you ask." We start to circle each other, and my dad smiles wickedly as we do. "Why do you torture Preston? With the nightmare?" "Because. He's a foolish lava creeper child who needs to be taken out."
"What has Preston ever done to you? He's seven years old for heaven sake. He's so young! What the hell is wrong with you?!" "I have nothing wrong with me. My problem... is you." This throws me off. "Me? Why me?" "I never wanted you in the first place. But your mother did, it's her fault she's not here."
That comment fuels my fire. "It was NOT her choice to not be here. She was forced to save me and die, or kill me and survive. She loved me enough to sacrifice herself. You don't care. You disgust me." With that, I swing at him mercilessly, and I can feel tears run down my face as I attack him. I take a jab at his sternum, and the blade sinks deep into him. He gasps, and I pull my sword, blood coating the blade in a thick layer.
He teleports away, and I despawn my sword. I haven't a mark on me, except for tears slowly drying on my face. Now my head hurts, and I know it's from the crying and painful memories again. Vikk raises his arms for me to lift him. I do so, and hold him against me.
He looks sadly at me, and brings his little hand up to wipe away tears. "No cr-crying is a-llowed, Sky. Stop it." I smile, but he still looks concerned. When I put Vikk back to bed, I head outside to clear my head. It's still cloudy and depressing from the memory.
In my head, I hear Dad. "You chose wrong, son. Without you, I would have no problems getting the Enders. You're a road block, and I despise you for it. If you could die, I'd have killed you when you were born. Think about that for a while longer, Skybrine."
Anger welled up inside me, but died down as I started to wilt to the ground. My head hurt from the painful thoughts, and I fell on my knees. A hand materialized on my shoulder. I looked up through a bit of tears, and saw the upset face of Anthony. "Are you alright, Sky? You seem... pained in a way."
"I'm not alright Anthony. My head hurts and your brother is with my dad. We don't have the strength to get him. I've been wilting under pressure, and I can't handle it. Anthony, Ty is gone, and I hate not being able to help."
"I know he's gone, but we need to get him before Herobrine kills him. We know he will, and it's only a matter of time. Tell Grace that she needs to stay home with Vikk tomorrow. We're going to get Tyler if it kills me. No doubt about it whatsoever. We good?"
I nod. But my head still hurts terrible, and I need rest. Anthony fixes me with a cold stare. "We leave the second I wake tomorrow night." And he picks me up and helps me stumble painfully to my room, where I crash.

-Ty's POV-
All I'd been doing was taking in fresh air, and bam! I'm suddenly in a cage. The last thing I heard at the house was Vikk gasping for air desperately. Then a hand came and grabbed my shirt, yanked me off the stair I was sitting on, and I was dropped in a cage. It hurt.
I curled my wings around me, and I sat in the corner quietly. A woman came to the gate. "Are you the famous Ender I've heard of?" I snapped, a bit ticked off. "I don't know, am I?" "Um... Ty?" I pulled myself backwards into the corner. "Then yes. I am the 'famous Ender'. What do you want from me?"
A man showed up behind her. It wasn't Herobrine, but he looked sort of like a human version of the dragon. He had black scales running up his arms, glowing purple eyes, black hair, black scales around his neck, and it looked like he had chains hanging off him. Oh, and he had the wings and tail- all black, no color whatsoever. It was the dragon.
The man spoke Endertongue, and I knew. "We want you to come home Tyler. You and your brother. This is your mother, and we need you home for a crisis alert. Where is Anthony?" Crisis alert? An attack? I had to talk to him, so I switched to the native language of the End.
"Anthony is in the fantasy forest not far from the city. He's in a home inside the pocket." "In the pocket? Why isn't he with you? Do you realize the destruction your brother could cause?!" "Of course I do. I was teleported to here, and Herobrine is the one who did it, so he has a teleportation free field around here. I can't escape."
The dragon then growls at me, and fiddles with the door lock. He gives up. "Damn it. You're right. This is why I told you to be careful when you were young. This is what happens when you do careless things." I growled in return. "What else would you expect?! I didn't choose to be dragged away from him by my shirt!"
The woman is standing there quite uselessly, but I'm starting to notice things about her I recognize. It's because she looks like me. She has my glowing green eyes while the dragon and Anthony have purple eyes. She has a green shirt, but no wings or tail. Her hair is the same auburn brown as mine, and instead of headphones, she has little green earbuds and a device in her pocket.
The dragon calls, "Tyler. Break the bars. How'd you not think of this before?" "I have. They're enchanted. Unbreakable." "Damn it. I'll be back Tyler." I watch as he walks out of my view. I hear shouts, and the dragon's signature roar, and the dragon reappears with keys in-hand.
He unlocks the door, and I come out, skirting around the dragon. I know he's angry with me for leaving Anthony, so I stay silent with him. The woman, the one I'd just been told is my mother, talks the whole time out of nervousness. But after a while, I start to get a little annoyed, so I stop her. "If you want to get out of here, be silent. If you don't, don't expect much from me if you get caught."
"Tyler! Don't speak to her that way. It's rude, and uncalled for." "Oh, like the cuts and scars you gave me as a kid? Sure, that was toootally called for. Notice the sarcasm, dripping from my voice?" The dragon just growls, and turns away. I catch sight of one thing, and one alone in the main hall. And I growl deep inside my throat.
It's Herobrine, but the dragon doesn't hesitate to step out. "So. Your Aether is still too colorful, as always. What happened to Notch? And the boy? Did they abandon poor Herobrine?" Herobrine stiffened. "What's it to you, Drake? Your boys are here, and you thought I'd be stupid enough to not realize the escape. I can see you, Ender." I snarled, and stepped out into the light.
