UltSans, after taking his breakfast, walked from the dining room to the lab. He walked until reaching the chair, and started using the control panel and turning all the monitors and screens on.
After a moment, he started planning his researches, but Zivo had detected something.
Zivo: "Asriel. While yoou were asleep. I had received some waves coming from a new timeline. After realizing few researches on my own, it comes from a timeline of the AU categorized as 'HorrorTale'."
UltSans: "Alright? And? Do you want me to can go through the infinite amount of timelines, and give supplies non-stop? Much things are inevitable, and I can't do miracles."
Zivo: "Asriel, please let me explain. You may want to go and check it yourself. There is something important than no other timeline has registered."
UltSans hesitated, getting frustrated by his AI assistant.
UltSans: "... Sigh Fine... I guess I'll bring them the usual, four crates of supplies, but just as a started gift or something... I wonder what this timeline has registered for you to bother me to go there..."
UltSans then got up and walked a little, and snapped his fingers and made four crates full of food supplies appear and fall. He then did a quick check to see if it was all good, and then quickly grabbed the crates to carry two in each arm.
Zivo then opened a portal, and UltSans walked through it. UltSans hesitated, observing around, seeing he was in Snowdin forest, and at his left was the gate doors to the Ruins not so far away, and also Sans walking to the gate doors almost there.
UltSans: "... That look... Hmmm... Isn't the appearance of Horror... Looks more like classic... Weird..."
Then, he placed down the crates, and moved a little aside one.
UltSans (Whispering): "Alright, so... This one for Tori, and the Ruins."
Then, he moved aside two crates, holding them and having his hands on the top edge of the crates.
UltSans (Whispering): "This two for Snowdin. Has to be more than few months if I'm correct."
Then, he moved the last crate aside, and wondering what to do with the last one.
UltSans (Whispering): "Huff... What about the rest...? Is not as they have any guilt from what Undyne does... But can't neither guilt Undyne completely... Still... I don't think this can be near enough for all from Waterfall to New Home..."
UltSans then sighed, and meanwhile, in the bushes in between the way to the gate doors of the Ruins, and where UltSans was, there were Flowey with a baby toddler Aliza, hiding while Aliza was shaking.
UltSans (Whispering): "I guess I have to come here more... Great... Well... More work, but also... I'll be useful, and be... helping..."
Flowey (Thought): "Another human? And what are those crates?... But how did another human survive in here?? And why looks so... normal? At least doesn't seem to suffer from hunger..."
Flowey then tried to move closer while remain hidden, but Aliza couldn't hold herself and started crying. Flowey hesitated and got scared, as Sans noticed, and turned to look where the cries were coming, so Flowey was shaking of fear.
But luckily for Flowey, UltSans was going where they were in a quick walk, with a worry and concerned expression. And after a very short moment, UltSans reached the bushes, and the two were now staring at each other.
Sans hesitated, observing how UltSans suddenly appeared while he never saw a human being in the Underground after Frisk left the Underground.
UltSans hesitated, and quickly observed the baby toddled Aliza, his expression sof surprise and concern.
UltSans (Whisper): "W-what?... T-that... has to be Aliza, but... Why is she... so small...?"
UltSans then looked at Flowey, and both hesitated. Sans after a time of hesitation, started walking towards them, and UltSans or Flowey noticed Sans approaching.
UltSans then kneeled down and grabbed Aliza by the armpits, to quickly start having his left hand used for her to sit on it, and his right hand to try to relax her with little touches and caressing.
UltSans: "Shhh, shhh... Don't worry... Boop, heh. Boop."
Aliza hesitated, and stopped crying, but continued sobbing and shaking for the cold she was having.
Sans reached them, but before Sans could say anything, UltSans got out of his pocket a food bar, giving it to Sans without even looking. Sans hesitated, surprised and caught off guard.
UltSans: "Sans, we'll talk later. Go eat, and go search your brother. I have to deal with this first."
Sans hesitated, as for him, UltSans was a human who just appeared, and was like this. But after a short moment, Sans decided to obey, and started walking back to Snowdin town while opening the bar wrapper.
UltSans then opened his right hand, and a flame appeared. He then started to slowly move his hand around Aliza, trying to warm her up. The closer he moved his hand, the smaler he made the flame be.
After a moment, Aliza stopped shaking, and he softly grabbed her shirt with teared up small parts trying to place it better adn to cover her more, but couldn't as that was all her clothes could reach.
Aliza quickly moved and hugged UltSans neck and shoulders, placing her head on his chest or his left shoulder. UltSans hesitated, but then slowly started to pat the back of her head and hair.
UltSans: "Flowey, why is she... What happened?"
Flowey hesitated, but was more relaxed and still wondering about UltSans, as like Sans, sees UltSans as a human who just appeared or doesn't know how is in the Underground.
Flowey: "Well... I was in the Ruins, and... a sudden basket fell while Aliza was crying. Toriel grabbed the basket and took Aliza as her child. But how do you know her name, or how are you in the Underground if you look... not in hunger?"
UltSans: "... Well... That's out of your understanding, but let's focus... How do you know her name? Did Toriel gave it to her?"
Flowey: "No, she was wearing a necklace where was written her name."
UltSans: "Sigh... Well... I'm not surprised humans threw a baby away... Maybe they did thinking she would die quickly by the fall, or eaten by the monsters..."
There was a silence for a moment. And then, UltSans moved down his right arm and hand, offering it to Flowey. Flowey hesitated and got surprised, wondering what UltSans wanted to do.
UltSans: "Come on, get on me. It will be better than how you go. Besides... I'm pretty sure you must be tired or something. Taking care of a little kid is hard, and for you?... I can say it has to be even worse."
Flowey hesitated, but then moved his roots around UltSans' right arm and placed himself on UltSans' right shoulder.
After a moment, UltSans sued his magic to make a crate float, the first one he moved aside for Toriel and the monsters in the Ruins. Then, he used his magic to easily open carelessly the gate doors.
UltSans then entered the basement of Toriel's house. Toriel was still there, and got surprised by seeing UltSans, a human she never saw, carrying Aliza, and also having Flowey on his right shoulder.
But before she could react, he made her be under blue magic, and crash against the wall at her left.
UltSans: "Before you say anything, I'll be straight and clear. I know everything and what's happening, and I'll be who adopts Aliza and will take care of her. And before you even try to reject, here you go."
Then, the crate floated and was put down in front of Toriel. She hesitated, but unable to move and processing everything while stares at the crate.
UltSans: "You have all the food you need for you, and the monsters of the Ruins. Probably for few months, but... I'm unsure, so I'll be here checking periodically or often, just in case."
Then, UltSans moved down his hand, and Toriel was out of the blue magic. Toriel hesitated, looking at UltSans and at the crate.
UltSans: "Just one question. Where is Aliza's locket?"
Flowey: "It's in a bedroom."
Toriel hesitated, and then tried to get the crate. She couldn't, so he used his blue magic to make the crate float.
Toriel: "... Please, come with me."
UltSans then started following Toriel through the basement until upstairs. Once upstairs, she leaded him to leave the crate on her kitchen, and he dropped it on the ground.
Flowey (Whispering): "Hey, human. I know you're trying to help and solve all, but she's dangerous. Go to that hallway, and enter the first door, that's where the necklace is."
UltSans hesitated, but then quickly walked through the burnt entrance and entered the hallway where the bedrooms were. He opened the door, and entered inside the first bedroom.
UltSans (Thought): "Weird timeline..."
Flowey: "The left bed."
UltSans then moved closer to the left bed, and before he could do anything, Flowey moved his roots and grabbed the necklace from under the pillow, and gave it to UltSans.
UltSans hesitated, observing the necklace on his right hand for a moment, and reading "Aliza" written on it.
UltSans (Thought): "I want to think she got thrown as abandoned for her better good, and not... for a sacrifice or something like that... Just... I hope it was because her parents wanted her to die without pain and be quick... I hope... it was for that..."
After a short moment, UltSans placed the necklace on Aliza's neck, and then left the Ruins to finish what he started.
When UltSans gave the two crates that were for Snowdin, he gave them to Grillby, as he considered the bar as a community place to eat and enjoy time with others and the warm.
Then, Sans decided to tell Papyrus to go to Grillby and ask if could help as a chef to cook and prepare food and meals, while Sans himself followed UltSans in secret.
When UltSans stopped at the end of Snowdin, looking at the entrance to Waterfall, he remained hesitant. Flowey stared at him, hesitating and wondering what was UltSans going to do now. But then, Sans suddenly appeared in front of them, scaring Flowey, but UltSans didn't react, didn't even flinched as didn't noticed Sans in the first place by the big height difference, and because UltSans was looking up.
Sans: "Ehm, listen... Human... I didn't expect any of this... ever happening, as I considered that all of us were going to starve and dust, but... Don't go to the Capital."
UltSans: "And what about all the monsters from Waterfall, or Hotland? Or even those who clearly live in the Capital of New Home? You want them to starve? With your only chance to change that, you still want them to starve?"
Sans hesitated, and there was a silence for a moment.
Sans: "... Is not as I can stop you, now can I?... You seem very determined, focused, knowing everything you're doing and what you'll do in every step. Is clear I don't have to warn you about the queen, bu-"
Then, Sans stops talking as UltSans throws at him a Voidspshere phone. Sans remains hesitative, surprised and having the device on his hands, not knowing what to do; while UltSans walks aside and continues his way with a serious expression.
UltSans: "Call me if you need me. All I do will be leave this crate on the Capital, and leave. I'm not interested in staying, and I have much to do. And if you want... and if I have to do so... I can get you some... Let's just say... 'Undying fish stick', which doesn't get rotten, if you know what I mean..."
Sans hesitated, and UltSans then entered Waterfall, and the last reaction of Sans was a creep smile and stare with no pupils while dropping a short cold giggle.
Sans: "... Heh..."
As UltSans continued his way through Waterfall, he saw many monsters, and so, he decided to give them the crate.
UltSans (Whispering): "Sigh... Well... I guess I'll have to come again more periodically than I expected... But why are there... way more monsters than should be?..."
Flowey: "What do you mean?"
UltSans: "Eh? Oh, uhhh... nothing. I'm just surprised by how many monsters are, just that. And because I'll have to come here more periodically in shorter laps of time than I thought."
Flowey: "Yeah. It has been quite a long time since the Core stopped working... I lost track, but I think it were... Months...? I'm unsure, but I say few months if I counted the days properly, as I think I did as... there was nothing else to do..."
UltSans hesitated, and then looked around, seeing the path to the temmie village, the path to Undyne's house, and other paths, and all the monsters getting stuff from the crate and other eating.
UltSans: "... Few... months?... Huh..."
Flowey: "Yeah, what about it?"
UltSans: "Oh, uhhh... N-nothing much, just... thinking..."
Flowey: "... Mhmm... Well, what will you do now? The monster of Hotland and the Capital don't got any crate, so... You'll come back and bring way more next time? Or what's your plan?"
UltSans: "... Let me think, but... yeah... Come back periodically..."
UltSans (Thought): "So... Few months, Sans looks like normal with the hole, and Toriel seemed quite normal but with clear differences... Their behavior was also similar to normal but with clear changes, but... not much... I didn't expecting 'this' kind of new. It's pretty obvious this timeline has a lot of way to go, but... I think I can change the entire timeline and make no one die, or no one else does if... anyone did already..."
Flowey: "Hey, human, are you up? Or did you fall asleep?"
UltSans: "Eh? Yeah? What?"
Flowey: "Good, you're awake. For a second there, I thought you fell asleep."
UltSans: "Uhm... Sure?... What."
Flowey: "Oh, nothing. Just waiting for you to move already. So... Got a plan?"
UltSans: "... Yeah... I guess you can say I do..."
Then, UltSans opened a glitchy portal, and in the other side, back at his personal void, left Aliza to sleep on his bed in his bedroom.
After a short moment, he was sitting on the chair of his lab, with Flowey over a side of the control panel of the computer.
Flowey: "So... This is your... nerd room?"
UltSans: "... Well, no idea. Is my lab, but... I'm not really a nerd, so... Unsure how could you call it."
Flowey: "... Yeah, a nerd room."
Then, there was silence, while UltSans had his arms in v on the control panel, and his hand grabbing each other and supporting his jaw while he looks down and thinks. Flowey remains hesitant, observing UltSans. And in the screens, is saw the timeline and the different areas as Ruins, Snowdin, Waterfall, Hotland, and New Home; even the Capital and the Core.
Flowey: "... And... I guess you'll have to face Undyne. But what will you do with her?"
UltSans: "With her mental state... The best, 'pacifist' option is... When confront her, drop food supplies when sees me, and leave. And if I'm right, if she eats, she'll start recovering herself, and her hunger won't affect her thought and decision processing, and then I'll be capable of solving the timeline properly."
Flowey: "The timeline? So you admit you're from another timeline?"
UltSans: "... Take this place as my timeline."
Flowey: "Wait, this is your timeline?"
UltSans: "No, but where I live, so... You can consider it as it is, inside some view aspects, of course... But I prefer calling it as my personal void instead of my timeline."
Flowey remained in silence awkwardly, while UltSans continued thinking.
Flowey: "... Well... What will you do with me? Let me here? Put me somehwere? Or..."
UltSans: "... What, are you expecting me to also adopt you or something? Wanting to be my plant pet or something like that?"
Flowey: "What? No! I'm no one's pet!"
UltSans: "Then? I'll let you on your timeline, and done."
Flowey: "Oh, alright... I guess I can put an eye on them, huh?"
UltSans: "... Bruh."
Then, UltSans grabbed Flowey, opened a portal, and quickly dropped Flowey on the other side, being the snow of Snowdin Forest, and then the portal closed.
