After thoughts and choices

Option A or B

Killua's P.O.V
I let go of Gon and look into his soaking  face and try to hold myself together but I just say "I'm going to be right back, I promise..." I try to smile but he can see right through it... "Killua.... I.....-ok..." I caress his cheek and give him a light peck on the head. I start to head back to the gate to apologize to Alluka, too wrapped up in emotion to notice any of my surroundings I feel a sharp stinging pain in the back of my neck before instantly collapsing, I try to reach out for the gate until I hear "it's so nice to finally have you back Kil..." I widen I eyes before I feel someone stomp on my neck and I black out....

Gon's P.O.V
It's almost been an hour since Killua left to go see Alluka I assume...I wonder if he's doing ok... I walk up the path to the gate when I suddenly notice, "b-blood..?!" I keep looking and seeing drops of blood until they're full on drag marks. Then pools... "Killua..." I run up to the gate and see that the blood just, stops... I can't tell who's blood it is specifically but I have a strong feeling in my gut that I know who's it is... I can't help but feel a strong pain in my chest and lungs as I struggle to breath at the thought of losing Killua... And his last words to me being "I'll be right back... I promise" .... I fall to my knees and find white/pink hairs floating in the pools of blood and I just feel nothing but pain from every corner of my body. Just ceaseless agony and torturous mental images of what most likely happened flashing before my eyes... I grip my jacket where my heart is and begin to tremble and trying to be strong, attempting to hold in my tears as no one could've lost this much blood and survived... But.... Why... Who would do this to Killua.... Why...... I suddenly have an image of who might've done it but, there's was such a low chance since he's so weak compared to Killua, why would Killua let him get so close with taking any action... That doesn't sound anything like Killua...I stand up with a dead-serious expression and determination to find him and save Killua... "Killua... Please be safe.... Please be strong... For me..."

Killua's P.O.V
I wake up to find myself in my cell but with chains with about the weight of 200 tones each chain, how did they even get these on me?! Just as I attempt to break free I notice that I'm covered in scars and gashes, blood pouring out as a never ending fiver. After about 3 hours all of my wounds dry out into scabs and I can feel my skin become extremely pale and my vision becoming drowsy again until I hear a voice that gives me enough strength to open my eyes and see who it is... "I-Illu..mi.." I try to speak but it feels like my throat is on fire from the steel chocker. "Ah Kil, it's been so long, why haven't you come to visit? Mom and dad get so worried. Not to mention Alluka.." As soon as I hear him say her name I jolt and tense up, remembering why I tried to come home in the first place. "W-where... Is... Sh..e.." I try to breath but my lungs feel as if they're about to collapse at any givin' moment... I notice Illumi holding something but the room is too dark and I'm far too low on energy to see what it in until it hits me... Literally, Illumi was holding a whip covered in barbs. It tears away my once smooth skin from my back. I try to ask what's going on until I see Alluka walk in with tears streaming down her face and a very distraught frown... What's going on... And what about.... Gon-!
