(Let's go back a long way and visit the day Sans and Papyrus watched Amina for the first time.)
"You lost her?!"
"Yeah, but Papyrus, she can run like super fast!" Sans said as an angry Papyrus stood in front of him, his face starting to turn as red as his scarf.
"Yes, but we were left to watch her and make sure she didn't go missing! What happened?! She went missing!" Papyrus yelled, beginning to stomp his foot angrily. He quickly turned Sans around and gave him a hard push forward, "Come on we have to find her, this instant!"
With that, Sans and Papyrus had to search their home for the tricky Wolf child, who was hard enough to see let alone find, she's so small you'd mistake her for something else. Yes, the skeleton brothers had been left in charge of the wolf child for the first time, who was only about six or seven years old. Her 'siblings' decided to play a prank on them and hyped up the child with sweets and as soon as Toriel left her with them she bounced around the house, though she was sat down by Papyrus and Sans had to keep on eye on her so Papyrus can get her something to calm her down, Sans watched her inch over to a table "Hey, stop that." She looked over to him her fluffy tail wagging quickly and put her hands on the wood surface of the table "You're about to make a bad choice, leading to a bad time, kid." She glared at him "Don't you do it." His threat didn't seem to phase her because she barked happily, flipping the table over and whatever was on it across the room Sans's eye flashed a blue "You're gonna get it, kid." She yipped and dashed off somewhere which lead them to the situation.
So, that was how SANS ended up losing the wolf girl they were suppose to be watching. He slowly walked into the living room. Amina was sitting in the corner, trying to hide herself behind a large couch that sat far from the television. Her hot pink eyes were huge as she peeked out to look at Sans who was now moving slowly toward her. "Hey kiddo, come out. I was only kidding, you understand, right? I was just playing." Sans told her, extending his arms to her as if she was a wild animal that would run away at the first chance that it got, and she was a wolf so that was half right. When he said the word play, though, something seemed to click in her brain and a huge smile found its way to her lips and her tail wagged happily. "Playing?" she asked, taking a few steps out from behind the couch. Wearing her usual sweater this one with a hot pink heart on it, shorts and mismatched slippers. Though she had on a red scarf like Papyrus's which Toriel made because she wanted one. "Yeah, kid, playing." Sans replied, his grin bigger now as he thought that she was going to forgive him and walk up to him. He wasn't wrong but she wasn't just going to walk over to him and not have some fun. She smirked her one fang showing, it wasn't her fault her mind was acting differently through candy and such, though her canine side didn't help her at all. Sans didn't have time to react before she had run off, only leaving a large gust of wind to show that she had been in that room only seconds before.
"Dang it!" Sans yelled, causing a small laugh and a snort to be heard out in the hallway. He ran out to where he believed the noise to be coming from but was only met with an empty hallway. Just before Sans went off to look for her once again, Papyrus rounded the corner and almost ran straight into the short skeleton. "Sans! I heard you yell, are you alright?" He asked, his eyes filled with worry as if he thought that something really terrible had happened. He always acted like that. It was something that he had a small problem with, "You sounded really angry." "It's nothing Pap. I just found Amina, and then she ran away from me. She really is a fricking handful. I have no idea how anyone can handle her. I wonder what she was like when she was really young." Sans said, rubbing a hand on his skull and letting out a large sigh, Toriel must have great control over her "Come on, let's just go and try to find her again!" The two of them went to go and try to find her, finding small hints of where she might have been. A few things had been knocked over. Nothing really important, just small knickknack kind of things and one of her chewing bones. It was as if she wanted them to follow her and that was rather taunting.
Nothing seemed to happen for about ten minutes..Everything was rather quiet and that made the two skeletons who were looking very tense, well Papyrus with more worry. That didn't last for long though as they heard a shout come from Sans's room, having the two dash into it only to find Amina caught up in that odd mini tornado he had Papyrus gave a shout and tried to find a way to get her out of it but Sans let out a laugh "I see you've found a good hiding spot, so good you've been blown away." Papyrus glared at him "Sans stop it with the puns and help her out of that thing!" After they did Sans set Amina down on the floor and chuckled at her pout "Are you going to be a good girl and behave?" Papyrus said wagging his finger at her, narrowing her eyes as she scanned the room. Sans and Papyrus didn't seem to notice Amina dashing off again, there was a pile of bones on the ground and the word 'No' was spelled with them. "Amina, stop it!" Papyrus said shouted out, which caused her to stop running around the room and become visible to the skeletons in the room, "If you don't stop acting bad I will tell Toriel about what you did and I don't think she wouldn't be very proud." Amina slowly looked over at Papyrus, a tiny frown tugging at her lips her fang poking out, she looked rather pitiful..huffing, Amina dropped the scarf she had on, and ran away again right between them "Come on!" Sans sighed, leaning over the couch, Papyrus picked up the scarf Amina had and let out a small sigh, maybe he shouldn't have been so hard on her, she looked really sad and because of him. "How are we supposed to find her if she just keeps running off whenever we get close to her?" Sans said, turning to look at his younger brother as if he had the answer. Papyrus actually was just as stumped as Sans and that really bugged him. They were left with her to watch and keep safe and they weren't doing their duties. "I believe that I may have the answer..." Asriel said, causing the two skeletons to jump and turn to face the quiet goat monster who had sneaked up on them. "What is it?" Sans asked being that he knew him already "Who are you?" Papyrus asked "My name's Asriel Dreemurr and I'm here to pick up Amina. Our mother, Toriel, sent me because she thought that you guys might have some trouble getting little Amina to stay still. I mean, I may have helped her get that way but really it is mostly her." Asriel said, shrugging his shoulders lazily though there was a smirk on his face. An unexpected breeze went through the living room and a high pitched squawk, after their eyes blinked, they saw that Amina was clinging to Asriel's leg. The young goat monster boy chuckled and picked her up, holding her close to his chest. "Thanks for watching her you guys." He said and flashed them all a grin before disappearing.
"Let's never, ever do that again." Sans said but Papyrus grinned "Too bad! I've already told Toriel we'd watch her for a whole week. There's nothing the Great Papyrus can do!" Sans flopped onto the couch.
