Attention: I got a beta.

This is my first beta'd chapter! Her name on AO3 is NeonBirds. I have to thank her so much, ugh. She's such a great person :D

There was one simple word to describe Frisk: determined.

When your grandmother came back from the shop, she and Solah brought a kid with them. At first you had no idea what to say to them, because: a) you were debating their gender and b) they were the kid that broke the barrier.

You didn't hate Frisk for freeing a race, how could you? They did the right thing, and they were only eight years old.

You knew that this kid was going places.

Solah was completely enamored with them, the two played nonstopping after introductions. Frisk was into everything they played; even though they were two years older than Solah they never refused her suggestions of having fun, even if they were a bit childish.

Frisk got a few pointers for making your sister happy.

So, apparently, Toriel has a date tonight with her ex-husband. Your grandma, being who she is, offered herself to watch over Frisk on the spot. And she didn't take a no for an answer.

At dinner, you realized that Frisk liked to let others talk instead. Solah babbled about how much she helped grandma at the shop, and also how much she liked Toriel's pie. Then, she asked you if you were feeling better. Frisk seemed to be interested as well, and before you could even open your mouth your grandma changed the subject smoothly.

You really needed to thank your grandma later.

It's been only three days since you arrived and so much has happened. She's always been there for you.

When Frisk decided to chat, it was to ask Solah if she was going to attend their mother's new school. That got your attention: you didn't know Toriel leaned into the education side, and now she had her own school?

Seeing your expression, your grandmother told you that Toriel and the king (her ex-husband) had built a school nearby Mt. Ebott. It was almost finished and just fifteen minutes away from here by walk – they were working on getting a bus to circle around the areas where more monsters resided: which was basically the neighborhood where you were staying.

Frisk told you that the coolest thing about their mother's school is, besides accepting monsters and humans, that it'll also be integrated with all the school years. It's basically going to be sorted into three buildings: one for kindergarten and elementary school, one for middle school and another for high school.

You weren't sure of how that was going to work, but you were impressed.

Finally, Solah replied with a sad no towards Frisk's question, and they also visibly saddened by her response.

You felt bad for the two. They must've formed a pretty solid friendship too quickly.

For some reason, your grandma went quiet and thoughtful after that.

After dinner, Frisk, Solah and you were playing Uno on the floor in front of the TV, while your grandma watched her soup opera. You were losing with seventeen cards left in your hands. Frisk was really determined to win the game, but they always let Solah be the winner in the end.

After Uno, you entertained the kids by announcing a surprise movie night. Your grandma was suddenly into it. She went straight to the kitchen to get some snacks before you could even say 'popcorn'.

As the children prepared the couch for movie watching, you decided to go help your grandma with the snacks. You weren't prepared to see her staring outside the window with a blank expression. Only the popping sound from the microwave could be heard.

"Grandma?" you coo.

"Oh!" she jolts a little, "(Y/n), hi hun! Popcorns are almost done." Her smile was so forced that you replied with a frown.

"Is everything okay?"

She pauses a little, before finally sighing almost tiredly. "Honey, I don't know… I'm still thinking about what happened yesterday." You walked towards her with a sad smile. "I'm not sure what to do."

"Oh grandmamma I—"

"I told Toriel." She confesses. "I told her and she worried too."

You were appalled. "G-Grandmamma…" you didn't know what to say. Were you angry? Did you feel betrayed? Strangely… No. For some reason, you weren't angry at your grandma: you were more surprised. Was she so desperate that she had to tell Toriel? And why would Toriel care? "It's… Okay…", what if Toriel told anyone else about it?

You immediately thought about Sans.

"Oh hun, you're pale! Are you feeling alright?" she was on you in seconds.

No, you weren't okay. You weren't okay since your father died. "I'm fine," you lie easily, you were used to it. "Uh, by the way… thanks for lying to mom and tell her I was sick." You smile timidly.

She scoffed and chuckled. "Your mother would send you home if she knew the truth and…" she gently scoops a line of hair behind your ear. "I just got you… I don't want to lose you again."

You felt guilt stabbing you right through the chest.

"Well it wasn't much of a lie, I think I'm coming down with something…" you admit sheepishly.

Her eyes go so wide that you'd think they'd pop out. "What?!" she slaps her hand in your forehead. "Do you have a fever?"

"N-No, it might be a minor cold. Just sneezing and coughing." You grin widely. "And I haven't had a fever since I was twelve, grandmamma."

"That doesn't mean you're free of them for the rest of your life," she retorts.

You roll your eyes and look at the quiet microwave. "Popcorn's done!" you cheer, changing the subject without her knowledge. It's better like that; you had had such an amazing evening. You didn't want to ruin it.

You all watched 'Diary of a Wimpy Kid: Rodrick Rules' after voting. You didn't mind, you liked the trilogy so why not? Besides, you get to see Devon Bostick. You don't need to say anything else about it.

Frisk and Solah fell asleep in the middle of the movie and when you were about to snicker about it at your grandma, you aw'd when you saw her snoring soundly as well.

Welp. You decided to quietly watch the rest of the movie and wait for Toriel to come and get Frisk.

Ten minutes later, a soft knock is heard from the door. You almost didn't hear it but luckily, you did. You carefully stand from the couch (Solah's head was resting on your shoulder, and now that you moved it, it's resting against Frisk's shoulder) and you head to the door.

You open fully and smile. "Hello Ms. To—"

"nope," the baritone voice cuts amusedly.

You look slightly down, it's Sans.

You hum discontent. "Oh… hello Sans." You greet him evenly.

"i'm here for frisk," he says as he casually walks past you. "they're asleep?" he asks as if he already knew the answer.

"Yeah, in the family room." You say as you close the door.

"did they bee hive?"

"Yes." You deadpan.

"i hope they were too frisky."

You roll your eyes as you walk ahead of him, you couldn't believe your luck. Besides, you were really hoping to see Toriel again. You can handle seeing Sans, so maybe you could show Toriel that you could see her as well and make her proud.

You arch a brow at your own thoughts, why did you want to make her proud?

You approached the couch and bend down towards Frisk. "Frisk, honey…?" you pat their head gently. "Frisk?" you sing. "Sans is here, time to go home, hun."

You didn't notice Sans staring at you from your back, his once small and wary pinpricks pupils dilated with a feeling he couldn't figure out, but watching you being gentle with the kid that saw him as an uncle and as a dad made something positive stir in the depths of his soul.

But only for a moment though.

Frisk whined a little as they slowly opened their eyes. They first look at you, then they look at Solah. Immediately, their cheeks got a little redder when they saw her head resting on their shoulder.

Unfortunately for them, you noticed that too.

"Ready to go home, oh, lover one?" you smirked.

They immediately stuck their tongue at you.

You giggled, and your grandma stirred in her sleep. It seemed like nobody in the room wanted to wake her up.

Sans chuckled softly. "c'mon kid, it's gettin' late."

Wow. You never heard Sans sounding like that… it was nice to know that he had this side.

You decided to help Frisk by moving your sister to where you were sitting. She moved into a fetal position and sighed quietly in her sleep. Frisk was free; they jumped to the ground and hugged your legs.

You instinctively patted their head.

Frisk didn't talk much, but their actions said a lot.

"You're welcome hun,"

They beamed at you. Then, they did the unexpected, they moved to your sleeping grandma and took something from their pocket, then, carefully, they placed a candy bar on her lap. You watched Frisk walk to your sister, and after digging in their pocket again, they left a pink hard candy right in front of her eyes. They smiled softly at her before looking at you.

They stretched their hands at you and in their hands was a lollipop. You blink, how in the heaven did they have enough space in their pockets for these things? You swear that it seemed like they weren't carrying anything all evening.

You wordlessly accept the lollipop and give a smile. They nod happily and stand next to Sans, who looks at you with an unreadable expression.

You walk the two to the door like a polite host; you even open the door for them. Only Frisk gives you a thankful look while Sans just keeps on walking nonchalantly. You didn't mind though. You wave happily at Frisk and you feel tiredness engulf you as you do.

"bye kid, see if ya tuck ya sister in properly." Sans suddenly says, winking at you.

You give him a blank look. How dare he? "Whatever… just take Frisk home safely."

It was late, and you couldn't help to feel a little anxious because of recent events.

"aww… worried about me?" he cooed mockingly.

"No, I'm worried about you two." You tell him with an edgy voice. "Just… No jokes and threats Sans. Be careful."

You almost wince with the look he gives you, he took the chance now that Frisk is busy entering inside the elevator.

"is that a threat?" he challenges with a deep voice. "do you know something I don't sweetheart?"

"No, you jerk!" you hiss. "Just- ugh. Never mind! I'm sure you'll be fine with your stupid and scary powers. Have a nice night." You step back inside and move to close the door, but Sans's voice stops you.

"you need to start spilling the truth if ya want me to trust you kid." His voice was now tired and… mopped? It sounded like he wanted something from you.

You looked at him with perplexed eyes. "Sans, I've been telling nothing but the truth- Well not really, there's something that did happen but the lie that came out of it ended but becoming real- But I swear, I-"

Frisk's worried expression made you halt.

Sans looked at Frisk too and ruffled their hair, "don't worry about it frisk, let's go home."

Frisk nods and gives one last wave at you; this one looked a bit forced.

You smile weakly.

But Sans wants to have the last word. "hey, howzabout you and I go for a walk tomarrow?"

You obviously know that he wants to talk about what you're hiding. But you couldn't help but to feel that his tone of voice suggested that you had no choice.

Would it really be a good idea to tell Sans? What could he do about it? If not, he'd get more suspicious about whatever he thought about you.

You sighed. "I guess…"

"great. smell ya later."

He entered the elevator and you closed the door softly.

It seems like you're spending time with that skeleton tomorrow.
