You returned home after another hour with Toriel. She seemed reluctant to let you go after the incident but with a few comforting words she finally let you go. Frisk stayed behind to stay the night with Toriel. You weren't surprised though, it had been a while since he'd seen his adoptive mother. You hugged Frisk and Toriel goodbye.

"I'll see you guys soon. Take care of each other while I'm not here." You said as you squeezed Toriel. "Give me a call when Frisk wants to come back to Snowdin, I'll pick him up. And if you want I'll fix the door so it goes both ways."

Toriel laughed. "Don't stress such things (Y/N). Take it easy for awhile. I don't want you risking another event."

You waved it off. "Don't worry about that mom, I've got it covered."

She stuttered a moment before smiling. "It seems I've adopted another child, haven't I?"

You were confused a moment before laughing. "I guess my Toriels' will have to share, won't they?"

We both laughed. "Take care my child."

"See you guys later."

You turned and left through the large set of doors. G!Sans waited for you, though everyone else already seemed a good distance ahead of you. The two of you shared a smile then walked side by side through the white waves of frost.

"I'm guessing the kid's staying over?"

You nodded. "I know that Toriel has a preset curriculum set up so he'll probably learn something while he's there too. Ha, I probably should've visited sooner."

G!Sans shrugged. "He would've learned something either way. He's surrounded by scientist 24/7. Kinda impossible not to pick something up."

You giggled, "I guess. But he'll need a bit more than science once the Surface is opened up."

You thought silently, tapping your chin until nodding in confirmation of your idea. "I'm gonna teach Frisk how to fight."

G!Sans withheld a laugh upon seeing your determined gaze. "You wanna teach the kid how to fight? He tried to flirt with Undyne over fighting her."

You nodded. "I know he's a pacifist, and this being his first set I'm guessing he's on a pacifist route. However, when that barrier opens up its gonna get real difficult for monsters and humans, Frisk especially."

You were silent a moment, remembering when you had heard the news. G!Sans cleared his thought, taking your attention once again.

"Why'd Frisk get it hard? Wouldn't he have been welcomed, being human and all?"

You shook you head with a sad smile. "You'd think so, but it's kinda the opposite. Ya see, once monsters make their appearance, all humans fell into one of three categories.

Most of us belonged to those who were scared. Until then you'd just been legends. Then theirs the hardheads that resolved directly to violence. Those were the people that shot on sight. Actually, the first few months of their occurring, it was war just beyond the barrier. Government officials from both sides had to settle that by literally walking into no man's land and screaming into megaphones.

Then lastly, and we were the smallest of the three populations, were those that found you curious. It may have looked like we were peaceful or gentle but really, we were all just curious about you. Often the scared humans turned to violence, so conflict wasn't uncommon. That was about when officials deployed the implant policy."

You stopped there, that memory being more than painful. Ultimately it was what set you on this path, which wasn't entirely a bad thing. But it also broke up the last family you had.

G!Sans waited patiently for you to continue. Seeing you had fallen silent, he pressed the question you almost found deadly.

"What was the implant policy?" He asked.

You remained silent, trying to find a way to make it sound less evil. You took a deep breath and continued.

"The implant policy took a select number, 100 total, from both sides. Each individual involved in the switch had a 'defect.' A record of crime, suffered in a tragic event, abused or been the abuser. They took the worst situations and used them.

They then forcibly put them into the society of the opposite side, like a vaccine. With each side seeing a picture of what the worst were capable of, they found ways to cope. If you haven't caught wind yet, I was one of the implantees."

G!Sans didn't respond immediately so you continued. "My checkered past and situation made me a prime subject to the experiment. So, one day they just showed up. This was after 'the thing' but I wasn't very stable. Working several shifts at deadend jobs and still trying to put my siblings through a decent life. When they showed up, I thought they were child protective services so I panicked.

That only gave them more proof against me. So they sat with me while the twins were at school and explained everything. They offered enough to ensure the twins all the way through college.... I took the deal.

They hated me. They kicked and screamed and tried to run away. When I dropped them off at the Foster's house, the last thing I heard from them was when my brother yelled how he hated me."

Your breathed hitched and a quiet tear rolled down your cheek. "So that's how I ended up Underground with Alphys. They took my education and placed me under her. Every time I got paid, I'd send 70% to the twins. It always got sent back."

Your voice faded away and broke. More tears joined at the edge of your eyes.

"I haven't seen them since then. They haven't even responded to my letters." You said in a hushed tone.

A hand fell against your shoulder and you stopped. You didn't turn to look at G!Sans, but you let him move around you. He lifted your chin so you looked into his gentle gaze. His thumb brushed away a tear gently as he looked at you. You broke the gaze, not wanting to face him after revealing such a scar of yours.

"(Y/N), look at me." He spoke softly. "What you did, you did because you cared about your siblings. You wanted them to live a life better than you thought you could provide. It's not your fault."

You shook your head. "I'm sorry Sans, but even if I did believe that... They hate me because of my decision. They told me a million times they preferred to be poor with me than to live in a Foster home without me. I... I let them down. I let my entire family down."

G!Sans gripped you more harshly, making you wince slightly. "Don't say things like that! It wasn't your fault and you should know that. You're smart enough to know that."

"But I-"

"No. Just stop there. You're not perfect, none of us are, but you did what you thought best for the people you cared about. That puts you in the right."

Tears streamed rivers over your face as you looked at G!Sans. You didn't understand why he still held you like someone who was a good person. To yourself, you were a monster, the only real one. And yet, G!Sans still had the courage to hold you, wipe your tears, kiss you better. It broke you down even more.

You moved your head against his chest and let yourself cry. You hadn't realized how much you were holding in, not wanting to show such vulnerability to Frisk. Every bitter thought and sour memory burst into your mind like a fresh breeze. G!Sans sighed heavily and wrapped his arms around you. Your body dissolved from its place in the snow, reappearing in his room. G!Sans moved carefully, lifting you behind your back and knees. He put you on the bed and removed your jacket.

You gave him a look of confusion but he continued his work. He untied and took off your (F/C) converse. Then he crawled into the bed next to you, his own jacket accompanying yours across the back of his desk chair. He curled around you protectively and you blushed.

"S-Sans? What are you doing?" You asked shakily.

He moved his head away from your head and gazed at your (h/c) locks.

"(Y/N), you're broken. You've tried and are still trying to bottle up so many things that any normal person would have lashed out with before now. You want to be strong but your past makes you feel weak, so it's leaking out. I don't want to see you cry, it hurts me. So I'm not letting you go until they all dry up."

You looked at him with a dumbfounded expression before smiling again.

"Huh, you sure know how to woo a girl." You teased quietly.

He chuckled and pressed skeletal lips against your head.

"Only for you dove."
