"C-chara?" My eyes widened in realization, as all the living daylights washed out of me.

"H-how? I-i t-thought y-you're d-dead?" I stuttered, backing away from her.

"Hush it now sis, I lived! Aren't you glad your dear sister is alive?" She purred, playing with her knife. Something about her was different, she looked scary, more like a psychopath.

Her hair's unruly messy as dust covered her bloody yellow striped sweater. "I-i...umm..." I tried to say something, but I'm lost for words, intimidated of her current look.

"Oh! I'd like you to meet someone!" She said in a high cheery voice. Flowey's vines emerged from the darkness, dragging a tall figure from behind as he pushed him to the ground.

"Gaster?!" I gasped, seeing him struggling to stand on his legs. His black cloak were tattered and worn, The white lab coat, soaked in crimson blood as he clutched his ribs. "Oh! So you know him!" She smiled."F-frisk....g-get a-away f-from h-her..." He coughed.

I rushed towards him, "Ah ah ah." Chara warned, pointing her knife towards me to stop on my tracks. "Why are you doing this?!" I yelled, knitting my brows in anger.

She retreated her knife and pulled gaster by his collar, as she slides the knife to his neck. "Stop!" I yelled, as my insides raged in fury. "I'm doing this 'cause I want to have fun!" She cackled, darkness filled her voice, as black liquid, oozed from her eyes.

"Y-you're n-not m-my s-sister..she would never hurt anyone for fun, my sister's long gone." I gulped, as my knees were shaking badly in fear. She simply giggled, as flowey squeezed gaster with his big thorny vines.

"F-frisk...r-run...s-save y-yourself.." Gaster flinched as flowey squeezed him tighter. "No! I would never leave a family ever again!" I firmly stated. "Aww how sweet, saving your boyfriend's father." She purred, smiling devilishly.

"Shut it! Just leave him alone!" I screamed, making flowey snicker. "I'll let him go if ~" she stopped in mid sentence. "What!" I yelled, clenching my fists.

"iF yOu GiVE mE yOur sOuL.." She smiled, as her red pinpricks glowed brighter. "No Frisk! Don't!" Gaster yelled with all his might. She cackled, then it stopped. "Sis...is that you?" Her voice changed, the sweet and normal one, her eyes back in those red orbs i once knew, she dropped her knife, trembling. "Chara?" Gentleness and confusion filling my voice.

"Sis! Run! He'll kill you!- ugH! shUt uP!" Her voice switched from the dark one, as she clutched her head, falling off the floor. I immediately approached her. "Chara! What's happening?! Are you alright?" I frantically asked. "No i don't want to do this anymore! Stay AwAY!" she screamed, backing away from me.

Suddenly, gaster summoned a goat skull that blasted the vines away, flowey hissed in pain as he disappeared in the darkness. "Come on frisk!" Gaster beckoned, limping, as he struggled to run, pulling my hand.

"No! We need to save her!" I screamed, struggling away from his grasp. "I'm sorry frisk we can't, but we'll save her whenever we're ready to face him." He said sternly, "B-but..." I mumbled, hesitant to leave her.

"Trust me, she'll be fine." He reassured, pulling me in the elevator, as I nodded slowly, watching chara disappear with hopeful eyes. Why..I don't understand...what's happening to her? I thought, as tears streamed down my face.

The elevator doors break free, revealing two figures ready to welcome us. "kid!" Sans exclaimed, blue tears running down his eye sockets, as he wrapped me in a hug.

"what happened?!" He exclaimed, facing me. I whimpered and enveloped him in a tight hug. "C-chara.." I heard gaster struggling to approach us. "Oh dear!" Alphys face palmed, rushing towards gaster, as she accompanied him on the couch.

"M-my s-sister..." I cried harder. "hey its alright, stop crying." Sans reassured, ruffling my hair, as he sat me down the chair. "everything will be ok, don't worry." He smiled, wiping my tears away. "Here have a glass of water frisk." Alphys handed me the glass. "Thanks" I smiled drinking the whole glass.

|| Sans' POV ||

"S-son? I-is t-that y-you?" Gaster coughed, catching my attention. "dad?!" I ran and hugged him. "i thought you were dead." I cried. "Aren't we both?" He chuckled lightly. Hehe seriously..i miss this old bones. I chuckled.

"but how?! I saw you fell?" I tilted my head, pulling away."Y-yes, after I fell, I w-was trapped into the v-void a-and due to the resets that h-happened, I was brought back to life." He smiled. "i'm still glad you came back." I smiled sitting beside him.

"Of course, I wouldn't leave the both of you." He grinned. "Speaking of you two, where's your little brother?" He asked as he fixed the bandage that alphys patched on his skull. "he's with undyne, training to be a royal guard." I casually said. "Oh I see, just like your mother" he chuckled.

"Gaster? Are you alright?" Frisk asked, pulling a chair beside us. "I'm fine, thank you frisk, please don't call me gaster, call me dad." He winked. "dad!" I huffed, man, my cheekbones are heating up again. "Oh! I thought you we're engaged with her son, my bad." He chuckled. Frisk looked flustered for a moment as she laughed nervously.

"it's fine" I muttered, it'll happen soon. I'll ask her out on a date next week, at the ball I smiled. "so what exactly happened?" I asked, changing the tense atmosphere.

"Chara and flowey joined forces to get frisk's soul" Alphys butted in, making frisk tremble in fear and worry. "Flowey came back because of a reason you see, to get Frisk's soul, and with that, he needs chara alongside with him." Alphys explained, wiping the dirt off her glasses.

"i should've known." I mumbled. "But, something changed when I felt chara's presence..." He knitted his nonexistent eyebrows as he rubbed his chin. "She became more powerful." He mumbled.

H-how c-come?! This is bad news...
