Blueberry P.O.V
Y/N hardly came out of her room after the incident. She hasn't even bothered coming to school. At least I was able to avoid all the bullies without getting hurt or something. I knocked on Y/N's bedroom door. The door opened and she stood there looking in perfect condition. "Hey Blueberry!" She says cheerfully with a bright smile. I smiled back and returned the hello. "You need something, Blueberry?" She asked. I nodded my head and she gestured for me to speak. My smile became small and I looked down. "I've been wondering why you haven't left your room lately. It's been 5 months after that...incident and you haven't really showed up to school or even came downstairs." Her bright smile faded and she looked away avoiding eye contact with me. I heard her mumble something under her breath. "Excuse me? I didn't quite get that." I say to her. "It's nothing, Blueberry. I'll just be in here if you need me." She replies, attempting to close the door. I stopped her from opening the door and looked at her with worry and confusion. "Y/N. You haven't come out of your room. It's like you're trying to hide something. Please, just come downstairs for once, everyone is getting worried." I tell her. She just sighs and doesn't respond for a while. It became an awkward silence until she sighs once more and started to speak. "I...I can't, Blueberry. I'm staying in my room, so I don't hurt anyone anymore." I was shocked from what she had just said. "Y/N you have to come down, everyone will be worried sick if you don't come downstairs!" I tried to motivate her and talk her into coming down, but she kept refusing. It got to the point where I finally gave up and left her in her room.

As I came downstairs, and see a bunch of worried faces staring at me. "Well? How did it go?" Pallet asks me. I just sigh with a defeated tone. Everyone looks more worried and disappointed that Y/N refused to leave her room. I explained everything to them and they sigh. "We'll just have to give her a little more time then" Gaster says to everyone. We all nodded with agreement. We all sat down and was about to watch Steven Universe until a loud scream was heard from upstairs. Everyone got up, alarmed and rushed up the stairs.

3rd Person P.O.V
After Blueberry left Y/N's bedroom, she closed the door and locked it with her powers so even if someone pick locked it, they still can't get inside. She lay on the bed and was about to get some sleep when something caught her foot. She looked down and her foot and saw a black, gooey tentacle wrapped around it. She followed the tentacle and saw Nightmare. Y/N's eyes widen with fear and she saw that menacing grin plastered and the skeleton's face. "Long time since our last encounter, huh, Y/N? It was pretty stupid of you to spare me like that" He laughed. "Now, it's time to finish what was started." His tentacles appeared out from his back and shot at Y/N's soul. She screamed out loud. She tried to fight back by getting the tentacles to loosen from her soul. Suddenly, pounding can be heard from the door and shouting as well. "Seems like your friends came to help you, again." Nightmare says with a chuckle. "Good thing the door's locked. Y/N smirked at him and used her magic to unlock the door. "GUYS!! HELP!" She shouts. The door bursts open and Nightmare just growl. Then he smirked. Nightmare placed his hand on Y/N's forehead. She started to scream in agony as if Nightmare is doing something to her. The others tried to attack him but Nightmare deflected their attacks with his tentacles. Then Y/N stopped struggling. Her screaming stopped. Nightmare took his hand off and Y/N stood up. As she opened her eyes, they were shown to be a dark, blood red.

Goth's P.O.V
As Y/N stood up, her eyes became a dark, blood red. Nightmare completely had control over her. She stared at us blankly. "Take care of them, Y/N" Nightmare says with a wider grin. Y/N's left eye bursts into F/C and S/F/C flames as a ton of sharp bones appear, Y/N threw them at us, we were lucky to dodge. Some of us blocked. The ground started to shake and the house came crashing down. We all landed on the ground safely before we were able to become bone meal. Y/N kept attacking. We kept dodging/blocking and tried to talk some sense into her.

Y/N P.O.V
I couldn't control myself. I just kept attacking my friends. The house came crashing down but I was relieved that everyone was safe. Soon enough, I heard something. A call. "Y/N!! If your in there!! Please!! Come back to us!!" It was Pallet calling. "Please, Y/N!! Come back!!" I heard fell shout. Followed by Ink. "Y/N! We know you're in there! If you can hear us! Please! Fight it!! We know you can!!" He said. I was determined to have control. I tried to fight the darkness that Nightmare had me caged into. I felt some control in my body. "Guys!!" I shouted. They all yelled my name in unison. The darkness held me again and I lost control of me. My body summoned my strongest attack and tried to hit my friends. They dodged/blocked and yelled for me to come back. Everything went black after that. I was in a white room. My clothes were white, the walls were white, the floor was white. I looked around.
*you call for someone to come.
I looked around, hoping someone can hear your call.
...
*BuT NoBoDy CaMe...
I collapsed to the ground on my knees and began to cry. Pleading for someone to come and help.

Someone, soon, placed a hand on my shoulder and asks; "why are you crying?" I looked up and saw myself looking down at me. "W-where a-am I?" I choked. "This is your mind scape. Your very thoughts lie around here." The skeleton who looked like me responded. "Why am I h-here?" I asked them. "Because you lost total control of your body. And now Nightmare has taken over.." My pinpricks disappear. Lost control? I thought. But then I heard my thought echo through the room. "Right. I forgot this place has my thoughts written all over it." I sighed. Other me just chuckles. "Is there any way for me to gain control of my body again?" I asked myself. "Well. Yes, there is. But it's gonna be a hard choice." She replies with a look of worry on her face. "Well? What is it?!" I ask, desperately. A black screen appeared, showing two options.
*find a way to your body and destroy then reset to when you met them.
*Call their names until they are able to hear you.
Geez this was a hard decision.
[find, destroy, reset to beginning] 💛 [call their names out]
"You have to chose wisely. You'll be able to remember everyone after your reset. But calling their names would be a difficult task." She said. I nod, knowing how difficult this decision is.
