Gaster the saver

you woke up in a cage you saw a really tall skeleton with cracks on hi skull he looked like G he also wore a white lab coat he turned his head to you with a blank look on his boney face ''so your nightshade why do you keep hurting my son?'' he said pulling a chair up to your cage his purple pinpricks stared into your (f/f) eyes you looked around it was the same creepy lab that G took you to just then G walked in you started to feel guilty your wolf tall swayed your eyes turning gold and flickering dangerously your claws came out you put your face to the bars of the cage ''do you really want to know'' you said with a sweet sickly smile showing your fangs they just stared at you in silence ''because am a demon and I love to see people and monsters fall oh and about the wolf pack G the never trusted you am the leader of all wolves and demons oh am your worst nightmare I remembered when my sister chara made frisk kill ever body even you sans don't think I don't know who you really are'' you turned you head to the other skeleton ''oh you must be W.D Gaster sans dad well I wished I could stay longer but I hate cages o by you howled and night fang walked threw the wall in a smoking black  form and ran over to you grabbing you up in his jaws and running back threw the walls but you jumped out of nightfangs jaw and scraped your knee really bad you walked back over to the wall and teleported  back inside the cage which surprised Gaster and G ''why did you come back dollface?'' H said feeling relieved ''its because since me and you share a soul you had a really strong desire for me to come back to you so here I am'' you said with your back to the two skeletons with you legs to your chest ''and just maybe just maybe i wanted to come back'' you murmured and your breath but what you did not know was that G still heard you (G's pov) i was in my room about to head to the lab because gaster had nightshade and wanted me too ask her questions about a few things so I teleported to the real lab and seen gaster sitting on a chair in front of nightshade  gaster looked like he was waiting for a reply but she just looked to the side and stared at me with her (f/f) color eyes I walked up to her and I started to notice her feel guilty her eyes became a gold color and flickered dangerously her claws came out she the put er face to the bars of the cage and said ''do you really want to know'' she said with a really really sweet smile that made me sick to my soul her fangs glistened in the light making them look really menacing she opened her mouth and said because am a demon and I like to see people and monsters fall oh she turned her head to gaster and said you must be  W.D Gaster sans dad while I wish i could stay longer but i don't lie cages she howled and a black wolf came threw the wall and gabbed her up and left threw the walls but a few seconds she came back threw the walls and sat back to the cage back to us '' why did you come back dollface?'' I said feeling relieved ''it's becuase since me and you share a soul and you had a really strong desire for me to come back to you so here i am'' she said putting her legs to her chest ''and just maybe just maybe i wanted to come back'' she said under her breath but i still heard what she said  ''hey gaster let me see the coller you made nightshade so she wont hurt anyone'' I said he handed me the collar i teleported behind her and put snapped the collar around her neck she jumped up in surprised ''get this fucking thing off me now!!!''she yelled trying to rip the collar off ''stop struggling sweetheart I cant have you trying to hurt anybody now'' I said with amusement in my voice ''why is that''!?! she said getting more angry then she already was ''because your coming to my house''.
