Undertale Scenarios

When Dimensions Collide

BP (Burgerpants):
A cigarette was burning between his lips, and his eyes were shameful. "Bad habit?" He slowly removed it from his mouth and held it in his fingers. "I've developed all sorts of bad habits since you've been gone." His arms crossed, and he seemed uncomfortable, brows furrowed. "And I may be a bad habit to you, but I just... I need you." His voice lowered, eyes moving to the floor. "Can't you just fall in love with this bad habit one more time?"

Chara:
Their jaw was tight, eyes red and dangerous. "(Y/N)." They spoke as if they were only teasing their prey. "Look at me." You could barely manage that. "I'm not me." They clutched at the hair on their scalp. "This isn't me, (Y/N)! I'm not me without you!" They fell, suddenly, to their knees and their shoulders convulsed uncontrollably. "I'm a monster without you. I don't want to be a monster anymore!"

Flowey:
You stared at him incredulously while his eyebrows strung together uncomfortably. "Idiot," he grumbled, clenching locks of his hair. "I'm an undeniably an idiot, but I needed you here." His gaze was fiery. "I can't feel without you. When you're not around, I'm lifeless." He took large strides across the room, then grasped your biceps tightly. "You're not leaving me again."

Frisk:
They stared at you silently, sadness coating their features. They seemed almost shy, tugging at the hem of their sweater and gaze avoiding your own. You took one step forward, and they took one step back. "I - ..." They lost their voice, and their eyes squeezed shut as they cleared their dry throat. "I love you." And that's all they ever had to say.

Gaster:
"I'm still determining how you left without either of using melting out of existence." His fingers were intertwined, posture perfect as he stared at you with eyes you barely recognized. "Perhaps it's because you never believed I was real." His jaw clenched for a moment, Adam's apple bobbing. "You never believed we were real." His blinked slowly before pursing his lips. "I'd like to show you how real we truly are."

Grillby:
He lifted his hands from the pockets of the dress pants he was wearing. "I am sad to admit I'm not quite as literally 'hot' anymore." He chuckled grimly at his own joke, before quieting upon the lack of your response. "It has been quiet without you, I haven't had to tell anyone to watch their language in so long." He stalked a careful distance around you, nearing a kitchen. "Shall we discuss this over a drink?"

Luu (Mad Dummy):
"Who in the hell said you were allowed to leave me?" Your eyes widened at his aggressiveness, and his eyes narrowed. And audible 'hmph' left his lips. "You're not really (Y/N), are you? No..." He seemed to speaking to himself. "Not my (Y/N). My (Y/N) wouldn't act so scared. My (Y/N) would be holding a baseball bat right now, ready to bash my skull in." He 'tsk'ed, a frown was etched deeply into his face. "I will wait until you are ready to be my (Y/N) again."

Mettaton:
"Darling." His eyes sparkled at the sight of you, and his heels clicked on the floor as he took rushed steps towards you. In one swift movement, he swept you off the floor and into his arms. "How I've missed seeing your beautiful face! I couldn't stand everything after you..." He held you gently against his chest, pressing a kiss to your scalp. "Don't you love me?" He breathed shakily as he awaited your reply.

MK (Monster Kid):
"(Y/N)!" Tears were already falling from his eyes, and he rushed over to you. You let out a startled squeak as a pair of arms wrapped around your torso and he stuffed his face into you neck. "I-It feels so good to finally be able to hold you!" He sobbed, although he was grinning against your skin. "If we stay here forever, I will hold you whenever you want, I swear!" His grin was easily replaced with a frown. "Please stay with me forever."

Muffet:
"Precious (Y/N)," she purred. "It is so wonderful to be able to see you again." She walked towards you with confident steps, but stopped a foot in front of you. "Life has been so bland without you, as I am sure yours was, too." She reached a hand out, caressing your cheek softly. "It is simply so black and white without each other, and I've missed the color of your eyes, the flushing of your lips." Her face inched closer, until you could feel her breath fanning across your face. "I've missed you."

Napstablook:
"It's... It's really you." Tears were collecting in his eyes. "I-I can't believe it's really you." He sobbed abruptly, and you moved to comfort him. "(Y-Y/N)!" he yelped as you pulled him into a tight embrace. "It feels like it's been so long and I-I thought I couldn't live without you." He wept loudly, furthering your guilt. "I can't live without you! Please tell me this is real!"

Papyrus:
"(Y/N)," he whispered in a voice that still managed to sound broken. You couldn't hold yourself back as you sprinted into his arms, wanting nothing more than for him to hold you again. "Sans, he... I..." He ran a hand through your hair, the other hand pressing against the middle of your spine. His voice began heightening. "I left him... BECAUSE I... YOU..." You hushed him, tracing circles against his chest. "I'M A MONSTER..."

Sans:
"I can't stay for long." His shoulders were tight, tense. He was frowning, and he looked like he hadn't slept in weeks. "Then again, I never really could, could I?" You both stayed a long distance from each other, a distance you were almost scared of. "But I needed to make sure you were okay. And I... I was getting kinda bonely." He winked, a fake, weak laughing slipping from his lips. "(Y/N), I... I'm sorry. Even if you're the one who left, I'm sorry." All emotions were wiped from his face, and he stared at you like you weren't there. "I deserve this."

Toriel:
"(Y/N), that really is you, isn't it?" She neared you, and you stared at her with wide eyes. "Don't tell me that you've already forgotten me." She gently tucked a strand of hair behind your ear, placing a kiss against your forehead. "I haven't forgotten you," she spoke, lips tickling your flesh. When she pulled away, you could see the sorrow in her eyes. "I can never forget you."

Undyne:
"Hey, nerd." Unlike her usual confident tone, her voice cracked. Her features were soft, and her smile was grim. "It's been a while since I've seen you. Her boots clunked heavily on the floorboards as she made her way to you. "A little while too long, I think." She leaned down and pressed a light kiss against the corner of your lips before carefully wrapping you in her arms. You both stood still, and she breathed out slowly. "I've missed you so fucking much."
