Sickly blurry green walls flashed by as two creatures ran down a long hallway in top speed. A hooded figure stopped in front of a door and placed a hand on a keypad and unlocking clicking noise could be heard. Quickly slipping into the blackness of a room before slamming noises echo down the halls, the door closed on the tall skeleton.

Papyrus stood there quietly wonder what he should do while looking at the keypad next to the door. A metal plate hung over the keypad with the name "Arial" carved into it. If he had to guess this was the door that leads to the girl's room. Leaning close to the door he could hear soft whimpers coming from the other side. Upsetting her was not part of the plan. He was just curious what a female skeleton looked like when Arial was sleep against his armor. All he did was pull down the hood to take a peek. Yelling, a human was probably not the best choice of actions, startled her awake. Next thing Papyrus knew he was chasing after her to this spot. Which must freak her out more? This was the worst first impression his newly discovered sister could gain from her newly found skeleton brother. What would Sans do in this situation? Make a few puns to lighten up the mood. If that didn't work, take a nap next to door until others came out to talk. This was the Great Papyrus, he could do so much better than that. "There's nothing to cry about…I can assure you…I, The Great Papyrus will not hurt you." He boosted placing a hand on his chest.

"Go away!" Arial screamed at the top of her lungs causing herself to start coughing.

"I can't…I promise no one will hurt you...Sis." Papyrus gently spoke, looking at the keypad, realizing it said unlocked.

"Who told you that?" Arial snapped in between tears.

"Alphys said Daddy made you, so that makes you family right?" Papyrus asked not sure if it were true or not anymore. Regardless if the girl was a sister or not, it wouldn't change the fact that he just wanted to help her.

"NO…I don't…deserve …both of you!" Arial's voice cracked between words.

"Why?" Papyrus was puzzled at her answer. How could she say that when they only met today in person. Seeing her almost fight Undyne to the death was not the best first impression of her character. He was still positive there was good in everyone, given the chance. They were family after all.

"I'm a freak… and…It's our fault…he, went" Arial cried while loud banging noises echoed through the door.

"No you're not…I'm not sure…what happened back then, but I know in my soul…you're a good person." Papyrus tries to speak in a soft reassuring voice, but it cracked a few times. A bony was handshaking in terror as it hovers over the keypad hesitating if the door should be open or not.

"We…" Arial's voice was cut off, falling forward while the door she leaned against slide out from under her body.

"Stop it…It's alright Big Brother Papyrus is here" the tall skeleton calmly said as he quickly caught Arial and pulled her close to the chest armor. Slowly standing up straight while cradling her. It was rude to enter a girl's bedroom uninvited, but he couldn't stand hearing her talk like that anymore. The orange soul felt like it was being tangled with emotions of sadness and bitterness that was not his own feeling. Where is this emotion coming from? Arial's soul? If it was, he needed to show her the past was not importation anymore. All that mattered was working on mending old wounds. So they could all look forward to a bright and happy future together as a family. Maybe something in the bedroom could help the girl's, worried heart.

An Orange light lit up in Papyrus' eye socket at the wonderment before him. The right side of the room had a white daybed with a bundle up pink "Mew Mew: Kissy Cutie" blanket lying on the floor surrounded by millions of tiny colorful stuffed animals. Anime posters covered the wall. Three bookshelves filled with manga books and a desk next to the table on the left side of the room "Wowie! So this is what a girl's bedroom looks like?"

"Papyrus, put me down" Arial cried looking up at the skeleton. A light shade of blush spread across her fleshy face as she felt him wipe away tears under her right eyelid. It was embarrassing to be carried around like a child, but there was a strange calming feeling to it. The purple soul in her chest felt understanding warmth in it. It's hard to explain, it was like she could feel Papyrus' emotions like it were her own. Telling her nothing to fear and everything would be alright.

"You're almost as tiny as Sans but lighter…" Papyrus chuckling, while heading towards the desk noticing sketches hanging on the wall above it. There were drawings of Grillby smoking behind the tavern, Sans sleeping at sentry station, Undyne hugging a blushing Alphys and other monsters in the Underground. Carefully placing Arial on her feet before leaning over the desk to take a closer look at the drawings. "Did you draw all this? Wait that's Metta … Happstablook and I." He gasped covering his mouth at the sight of a drawing of a tall skeleton kissing a pink ghost with an emo haircut.

"Yes…I'm Sorry…I didn't mean to spy…You both looked cute together." Arial spoke nervously while pulling the hood over her head.

"Really…." Papyrus shouted in excitement jumping up and down. Unlike Sans who was against his relationship with Mettaton, it was super cool to finally have a sibling that accepted it. Maybe if she also had a special monster in her life they could go on double dates. That thought went away noticing a drawing of a monster he didn't remember but strangely looked familiar. It was a portrait of a skeleton monster. The features in the skull where delicate and smooth giving off appearances of a female. Around her neck was a long scarf. "She's pretty, who she is?" Papyrus asked, eyes traveling down looking at the scarf around his own neck.

"Not sure…She's always singing to me in my dreams and giving me hugs." Arial smiled while fingers lightly touched the drawing. Closing her eye for a moment as a loving warm feeling washed over her body. This caused her to feel more relaxed and take down the hood "When I wake up I always feel happy and safe…It reminds me of the same feeling I get when I'm with Alphy."

"Do you think it was your birth mother? You kind of look like her," Papyrus asked using one of his gloves to cover the human side of Arial's face then look back at the drawing.

"I'm a test tube baby, Papyrus…Gaster grew me inside a large container until I was at least three… I don't remember, it seemed that I was sleeping the whole time… "Arial answered with sadness in her eyes before stopping to turn attention back to Papyrus who was messing around with objects on the desk.

"I thought Sans was the caption of sleep head." Papyrus giggled picking up markers and pencils to place into an empty cracked clay pot labeled, Flowey. Not sure if objects went there, but that table was so messy. It kind of reminded him how Sans kept his room. Sure, an artist is known to be messy, but this skeleton brother was not going to stand for this. Maybe on his next free day, he could take her shopping to buy a few things to organize her art supplies and show her how to keep the space clean. There was already one messy skeleton to clean up after and there was no need for two of them in the family. "Is this your sketchbook?" he asked, finding a book with a black hardcover under a pile of scrap papers.

"Don't open that!" Arial yelled out of the blue, reaching out take the book from Papyrus. The skeleton held up over his head giggling a bit, opening the book to a random page.

Papyrus heart beat fast at the image of nude humanoid cat boy straddling older cat boy. Quickly flipping to another page to Merman sucking on….. "Ummmmm…" it was all the skeleton brother could muster cover his mouth from view while eyes were glued to the pornographic images.

"I'm a fujoshi….Do you have to keep flipping through that?" Arial looked away in shame that her own brother was looking at her dirty boy on boy fantasy. The sound of turning the pages made her blush a deep shade of pink. "It's embarrassing, Papyrus!" she screamed jumping to smack the book closed and pulling it close to her chest.

"I think it's good." Papyrus patted her on the head while looking up at the ceiling. It felt a bit awkward finding out his younger sibling also had an interest in sex, especial that kind. It wasn't that he was innocent or anything about the subject on intercourse. Sure he had a few sexy magazines under his bed and stole some of Sans' DVDs from time to time, but this was his little sister. The youngest child should be a pure and innocent angel, not filthy mind like the rest of the family. "Wait is that how Sans feels about me?" he thought, looking down at the blushing girl before him. "How did you figure what can do what?"

"UnderNet…Please don't tell Alphy, she would have a heart attack if she knew…She still sees me as her little girl." She replies placing the book back on the table.

"I know how that feels…Sans still treats me if I were still a child too… Papyrus nods his head in agreement heading towards the bed and took a seat. "I'm almost an adult!" he huffed, crossing his arms looking up at nothing particular.

Arial's stomach made a light grumble while heading toward the bed. "I think I have some sweets somewhere," she said in a muffled voice while digging under her bed and pulling out a purple bakery boxing that was in the shape of a milk carton.

"That's not real food…Why don't I make us some spaghetti." Papyrus mention, watching Arial take a seat next to him.

"Unless it was frozen or canned it's not possible…Microwave food only." Arial remarked pulling the tabs down on the box in order to open it.

"How horrible…No wonder you're just skin and bones….you're not…." Papyrus' words were cut off as a soft object was popped into his mouth. To him, the sight of junk food and sweets never looked appealing. Most of it was empty calories and had no nutrition value. Eating junk causes the body to be sluggish and he need the energy in order to train to be a Royal Guard. The soft fried dough object in his mouth was surprisingly good. It had a light sweet texture with a hint of brown sugar and webbing decoration. "Wowie!"

"Good, right?!…It's a donut hole from the "Muffet bake shop"…Mom always stocked up on them when there was a half off sale going on…My favorite ones were filled with strawberry jam and with webbing glaze." She smiled before popping a round little ball into her mouth.

"That's the first time I heard you refer her as your mother..." Papyrus commented taking a mini donut. He did skip breakfasts so a few more balls of sweetness shouldn't hurt. "Could you call me brother?" he asked feeling a little bit jealous of Alphys, edging closer to her.

"I can't….Papyrus…Papyrus…" she shouted in giggles as Papyrus quickly grab her human foot and started tickling her. She looked up to see a glove hanging from his mouth while legs wrap around her waist keeping her from escaping. "Alright…Big Brother...Stop it." Arial gasped for air between fits of laughter.

Papyrus nodded his head in satisfaction while released his grip on Arial's foot. "Heeee…I win" hugging her tightly feeling the warmth coming from both their souls.

"As your prize, you're welcome to take any of my drawings."

"Are you sure?" Papyrus asked looking over at the sketches on the wall "I have an idea I will invite you and Mettaton over for dinner tomorrow. You can sketch us and you can try my spaghetti."

"Big brother…I'm not sure I'm ready for that," Arial spoke in a low tone of uncertainty about meeting a superstar like Mettaton. The robot was a childhood friend to Alphys, but how did Papyrus know him too? The robot star was known to broadcast gossip and juicy stories on his news show all the time. The thought of her family life being on display for all the Underground to see was terrifying.

"Did I forget to mention Happstablook and Mettaton are the same monster?… Don't worry Sis, my Shining Star is going to love you…There's nothing to be scared of…" Papyrus said noticing the fear in little sister's eyes. "Remember the Great Papyrus will protect you." giggling a bit, he pulled Arial into a big hug causing her to drop the donut box. Tightly holding on until her frown was turned into a slight smile.

"I'm sor…ry…I didn't mean to interrupt the bonding time." Alphys' voice came out of nowhere as she entered the room to find the youngest skeleton siblings hugging each on the bed. She hated to interfere but it's getting close to lunchtime. There was some important information that needed to be discussed with Undyne that sort of involved Arial to be present. It was a little bit too early to fully trust the skeleton brothers completely with information about her daughter. Papyrus seemed harmless, but Sans, on the other hand, reminded her of Gaster. "I'm fi...finished with giving Sans a checkup...He's alright just n...needs a little rest…and is sleeping in the living room r...right now."

"I should be taking Sans home…" Papyrus slowly released Arial, slipping his glove back on, and stood up. A bit of sadness washed over him as the connection he felt between their souls diminished the farther they were apart from each other. "Dinner will be ready tomorrow at 8 pm sharp…I will see you then, Ariel." He said not giving her the chance to argue, jogging out of the room, and kept going until he found Sans sleeping peacefully on the couch next to Undnye.

"Hey, there pal….How did it go?" Undyne asked tearing her eyes away from the television to look up at Papyrus.

"Splendid…Invited her to a family dinner tomorrow…Maybe we can have a sleepover too." Papyrus shouting in excitement at the thought of all his loved ones bonding together while eating magnificent spaghetti dinner.

"That's great Paps…That means Alphy will be alone tomorrow night." Undyne smirked to herself while her blue cheeks blush a deep blue. If Arial was going to sleep over at the skeleton brother's house then Alphys would be home alone. This would give the water monster the perfect chance to come over for pizza and flirt with her crush. If she was lucky, the right kind of mushy romantic anime could lead to a making out session and maybe…. The blue scales on her cheeks turned an even darker shade as Undyne's mind started to be filled with sexy images of a yellow dino that unsafe for any children to comprehend.

"Are you alright, Undyne? …Your face is turning a dark shade." Papyrus asked, wondering if he should go get Alphys or maybe she was upset about something.

"It's just a little warm here for my taste, Hotland and all." Undyne lied, watching Papyrus bend down and carefully pulling Sans into his arms. "Anyway, you should get lazy shack home…Oh, Papyrus next time you try to stop one of my battles...I'm going kick your ass" Undyne said jokingly with a smirk on her face.

"It would be an honor to battle you….Nee…hhheeee!" Papyrus called out in glee while heading down the steps, looking down once in while making sure he didn't wake the sleeping skeleton. His orange soul beamed with excitement about what tomorrow was going to bring. Most of the day would be spent working at the sentry station and recalibrate puzzles. Once the job was done he would need to rush home to clean everything and make dinner. Now if only he could get the Underground's most lazy monster, to pick up his stinky sock in the living room. It would be very helpful and one less thing to do on the list. There so much to do and so little time.
