The next day, Frisk woke up screaming again. This time before she even managed to become aware of her surroundings, she felt Sans rubbing her back in comfort.

"same dream?" He asked, voice gentle.

"Same dream." She confirmed. Sans stopped his circular motions and gave her a tight hug. For a moment Frisk flinched, before melting into it. She still found it difficult to believe that Sans truly cared about her, it just felt too good to be true.

Sans noticed how Frisk flinched and grimaced. Dammit, he didn't want this, the child's fear of him was painful. If only he had known what was going on, he should have been able to figure it out on his own. Now every minute he spent with this… babybones, the more obvious it became that she just couldn't have hurt anyone, she just too gentle, too timid, that added with his memories of the first timeline… Sans felt like a very stupid skeleton.

"babybones…"

"DID SHE HAVE ANOTHER NIGHTMARE?" The two's attention was brought to Papyrus' concerned voice and they both turned their heads to see him standing at the door.

Frisk nodded. Papyrus frowned and joined the cuddle pile. Frisk sighed in contentment. It had been a long time since she had felt so loved.

Papyrus withdrew from the hug. "TODAY, IS THE GREAT PAPYRUS AND HIS BROTHER'S DAY OFF. SO, I PROPOSE THAT WE SPEND TODAY TEACHING YOU HOW TO USE YOUR MAGIC!" Papyrus beamed with excitement.

Sans also let go, "good idea bro."

Frisk shook her head, "But… I don't wanna fight anyone." Not ever. She had seen way too much pain and death already.

Sans hummed, "we could teach you how to summon your Gaster blasters. they can be used as an attack, but they can also be good pets."

That… That perked Frisk's interest.

"THEN IT'S SETTLED! WE SHALL BEGIN TRAINING AFTER BREAKFAST!" Papyrus ran down to start making breakfast, and Frisk got up to help him (and save Sans and herself). A wave of dizziness made her head heavy and she flopped on the floor before she made it to the door.

"be careful babybones, you can't get up too fast." Sans cautioned. Frisk's looked up at him and nodded, eyes troubled. "don't worry, ya get used to it."

Frisk made it downstairs slowly, bracing herself against the wall. It was like she had stayed up 'till midnight and had woken up early, when in fact she had in fact gone to bed right after dinner and had woken up much later than she normally did. The fact that she was having nightmares obviously wasn't helping.

By the time she reached the kitchen, it was far too late, Papyrus had even started to dish the spaghetti. She looked to Sans with an apology in her eyes. For a moment, he looked confused until realisation entered his eyes, he shook his head and gave her a pat on the shoulder.

They ate the meal as fast as their skeleton mouths would allow before Papyrus pulled them out the front door and into the clearing.

Sans looked at Frisk who was fidgeting nervously. "since you're so excited pap, why don't you summon yours first?" He wanted to gage Frisk's reaction before he summoned his own Gaster blasters, unsure if they'd bring up bad memories and freak her out.

"I DON'T NORMALLY SUMMON MY GASTER BLASTERS, AS THEY TAKE UP A LOT OF SPACE." Papyrus explained, before raising his hand, it took a brief few seconds of concentration before Papyrus' large Gaster blaster popped into existence. It was huge, taking up the space equal to the size of the brothers' kitchen.

Frisk stared wide-socketed at the blaster, amazed at the sheer size of it. Papyrus smiled cheerfully before motioning her to come closer.

With shaky legs, she took a step closer, checking how the blaster would react, when it didn't do anything, she took another. And another, and another, before she ran to Papyrus' side a couple of feet away from it.

"GO ON, SISTER." Frisk looked up at Papyrus, confused. "NYEH-HEH-HEH" He chuckled, gently taking her hand and brought it to the Gaster blaster's nose.

Frisk flinched when she felt a puff of air whistle through her hand as the Gaster Blaster gave it a good long sniff before it nuzzled her to the ground.

"Hehehe," A giggle escaped her as she raised her arms to protect her head from the blaster's nuzzles. She turned to the brothers with a huge smile on her face.

Sans sighed in relief, he had been nervous for a second there.

"the more time you spend with your blasters, the more attuned you become with them. with enough time, you can communicate with 'em telepathically, like i can." Sans summoned his own blasters and had them join Papyrus' in nuzzling Frisk, making Frisk's giggles increase in volume.

When the brothers decided Frisk had had enough they called of their blasters and unsummoned them.

"now it's your turn to try babybones." Frisk felt a cold nervousness enter her chest. She didn't feel ready. What if she lost control of her blaster and it hurt one of the brothers? Sans would be so mad at her.

"come on, babybones, at least give it a shot." Sans encouraged. "i taught pap so i know what i'm doing."

Frisk looked up, "A-alright."

"great." Sans walked so he was right behind Frisk. "first, i want you to focus on your soul."

"Okay." Frisk closed her eyes, feeling her new soul at the centre of her being, it felt… different than before somehow.

"don't close your eyes." Sans scolded. Frisk immediately opened her eyes, not wanting to upset him, but Sans didn't look angry at all, just stern. "you can still feel your soul, right?" Frisk nodded, realising she could. "now, i want you to see if you can feel your magic pumping through your soul."

Frisk narrowed her eyes, now carefully paying attention. She could feel it, her magic, although she could guess it was pumping through her soul, it felt more like air breathing through lungs.

"Y-yeah, I can feel it."

"good. now i want you to take it and pull it out in front of you," Frisk mentally pulled the magic from her chest and brought it in front of her. To her amazement, she could actually see it in front of her, in the form of a dark blue mist.

"that's right, like that, good. now, to make it a Gaster blaster, you have to let it go a bit, let the magic become alive."

This Frisk struggled with, she tried, but it felt like something was holding her back. Eventually, the mist dissipated leaving nothing.

"I'm sorry." She apologised, embarrassed that she had wasted Sans' time.

"don't worry about it, i can't expect you to get it right first try, can i?" Sans chuckled, before checking an imaginary watch. "now would you look at that, it's break time, let's go to grillby's"

"SANS! WE HAVE ONLY BEEN TRAINING FOR AN HOUR!" Papyrus groaned, Sans looked down at Frisk.

"quick hold my hand, i know a shortcut." Grabbing onto Frisk's hand.

While Frisk had experienced Sans' shortcuts as a human, the magic had always overwhelmed her too much for her get a sense of what was going on, but this time as a monster, it was so much clearer to her.

She could feel her soul being pulled through… something?... and into something that could only be described as emptiness, before her soul quickly bounced off something solid and out of the emptiness, Sans and her arriving inside of Grillby's. She blinked, hearing everyone welcoming Sans back.

"Wow." She said in a quiet voice, amazed. Sans heard her and gave her a small smile that said; 'i know' before he looked back up and waved to everyone.

"(Who's this?)" Dogaressa is the one to ask. Everyone nodding to show their interest.

"This is Frisk, she's my new little sister." Everyone smiled and greeted her, not asking any questions. Frisk smiled brightly, this was nice.
