"On it, Doc" Sans teleported close to the sick bed and placed Toriel there 

"I hate you for doing that" Half-mad and pale looking Toriel coughs with remnants of blood on her palm

"Please, worry about that later..." Alphys said running towards her for a quick check-up "...I'll take things here, you go and continue help Undyne and the rest out" as she waved away at Sans' direction to quickly move.

"Alright, I'll see myself out" He turned around facing away from them

"Goodluck, Sans" She says as he took a few steps, snaps his finger and completely disappears in thin air

"W-WAI-...-it... I couldn't even say thank you..." she placed her palms on her forehead, sighs and looked at the Doctor's direction

"He knows, no need to worry. We got more important stuff to work on, Ma'am" She raises her hands and heals Toriel's wounds "First, we need to get you in a much more better shape." 

"hah... you're right... and thanks- to you too..." She looked at the Doctor's direction with eyes teary about to let a tear fall but quickly wipes it off with her palms "T-theres... a human that fell down... I tried to help but it looks like... I made the wrong choice... and that skeleton just came in time to save me..."

"Yes. We've been aware of the Human"

"Y-you do? How?"

"Our Technology detected an Anomaly entering our Universe's space, and proceeds to..." As Alphys continues to speak, Toriel out of nowhere starts to turn her head a little bit and gets a bit lost in all the Nerd stuff she's mentioning to her "Well that sums it up Ma'am. You've been living off-grid for far too long. You need to be exposed to new Technology"

"B-but I have this cellphone!" 

"I meant the latest Trends. That's already outdated... Ma'am."

Toriel looking defeated while holding a old model of a cellphone laid back down and stared at the Lab's ceiling and keeps the phone away on her pocket "I'm really sorry... If only I've been aware of it."

"No need to be aware of the Trends, you just need a certain someone like a Friend to let you know."

"You are right..." She wiped off a tear that releases from her left eye, exhales deeply and continues to stare at the ceiling while being hand-healed by the Doctor "Though... A certain Flower warned me about the arrival of a Human... I should have listened..." she then shed a few tears as she closed her eyes and sobbed a little for feeling the guilt and response to her own trauma "I-I just don't want another human dying at the hands of that killer... I'm so sick and tired of it when there are other ways he could have done more better..."

Doctor comforts and pats her shoulders calming her for a bit "It wont happen Ma'am, we got it all under control 'for now'"

"I have your trust in the fate of the Monsters..."

"Now please, take a rest while I switch you to a healing machine, my powers are about to get drained and... I need a full night's rest to restore it all. However this is a bit slower but the procedure is 100% safe."

"do whatever you must... I should be thanking you and Sans for saving my life."

"No worries, Ma'am. I'll bring you to the Special Infirmary now." Alphys pushed Her bed towards the Infirmary and plugged an electric under her bed and a large green bubble summoned from within and covered her small area healing her "Now please take some rest, you'll need it. Ring the emergency button if you need something, My nurse Mettaton will be right with you in an instant."

"Thank you again..." she proceeds to close her eyes and relaxes eventually falling in a deep sleep. 

The doctor walks outside the Infirmary, to her computer and continues her work while her Nurse Mettaton gives her her daily tea to drink "Please watch over the Patient at our Special Infirmary, Mettaton. If she ever needs assistance, quickly come at her expense. She'll need all the treatment and it may take a while for her to be fully healed."

"As you wish, Doctor~" Mettaton circles away from her while holding a small circle tray and disappears from her view.

"Now... where we're we?"

At the Throne Room...

From the distance looking from the entrance of the throne room can be seen standing near a Flower Patch at a wall behind the Throne a large furry figure sulking from watering the flowers. A Form twice the size as Sans' height there a messenger appeared panting and running, hurridly delivers a letter.

"Your Majesty..." he catches his breath and wipes a sweat from his forehead "a Letter." The messenger greets the King with a bow with its arms stretched forward holding a Letter, the King placed the water can on the floor, turned around to the Messenger, and received the Letter. The messenger then moved backwards slowly before raising his head and walks away.

The King opens the letter and as it reads, he gasped and it echoed through the silent room. He sobbed, fell down knee first on the floor as the letter flew away from his palm. His hands dropped too to the floor and began to sob louder, thumping his hands in anger and despair "H-How could this happen..." 

"There's only 1 hope left..." He sniffles, stands back up, and returns to his normal posture as he walks behind his throne reaching for a small chest from its small hidden compartment. Upon opening a light illuminates his face and the item inside floats infront of him. A Crystal ball shape appearance that shines bright light appears, a golden infinity loops inside the small crystal. He reached for the crystal, dropped the small compartment, closed his palms and places it near his chest. "Please... If there is hope... I wish for the Aetherial Beacon to find its deserving host with a pure heart to save our Universe." He closed his eyes, opened his palms and the ball disappears from his hands.

"Let this be... our last resort..." looked up to the broken ceiling of the room and proceeds to walk away

Back in Waterfall...

You can see Undyne guiding the Citizens from Snowdin and Waterfall just outside her house, in her Royal Armor prepared to protect the citizens. The crowd anxiously walking forward, where some monsters are feeling distressed, panic, anxious and nervous of the news. "Please, keep walking forward everyone to the hotlands. Our other Royal Knights will keep guiding you and will be providing goods temporarily for support." raises her spear and points towards the direction everyone is walking up to "It wouldn't be long now until the crisis will be diverted and our Knights and Scientists are working together to put an end and everyone will be safe."

A monster kid stopped walking in the middle of the crowd, hugging a teddy bear, sobbing and weeping the tears from her eyes shouting and looking for her mother. She notices this and immediately passed her duty temporarily to the other Knight beside her and went through the crowd towards the Monster Kid "Excuse me, coming through"

"M-mommy..." she sobs, sniffles and wipes the tears from her eyes and confusedly looks up from the crowd trying to get a glimpse of her mother's figure somewhere. A passerby bumps to her hard, not noticing the kid led both her fell down losing the grip of her teddy bear that flew a few meters across her. Upon looking up, the teddy bear gets picked up by Undyne and proceeds to help the kid stand up "Are you alright? where's your parents?"

The kid continues to sob, hugs Undyne "I... I lost my mommy..."

"What happened? did you know where she went?"

"A man bumped into us sniffs and I got pushed to the side losing my mommy's hands"

"here kid" She gave the Teddy Bear "Alright, Let's go look for your mother okay?" the kid nodded and she lifts the kid up on her shoulders "Call for your mom if you see her"

"o-okay"

They then proceed to walk slowly through the crowd. Upon walking, Undyne senses a sharp ominous aura from behind that made her shiver a little, however its very faint and barely anyone nor her knights could sense it up. She ignores, brings her focus back to help the kid, and continues to walk forward suddenly hearing a voice of an adult Monster calling for somebody. 

"Mom!!" the kid's face lits up, Points at the direction of her Mother, her feet wiggles and her teddy bear almost fell again but luckily Undyne could catch it in time.

"Mira Honey!!" her mother notices her on top of Undyne's shoulder thus she then proceeds to lower Mira down and runs straight toward her mother "Mommy!!" she hugged her mother's legs in fright while she crouches down, hugs her, looks at Undyne's direction and slowly walked up close to them where now she carries Mira on her shoulders "Thank you, Captain." she appreciates her help "Is there anything I can do to return the Favor?"

"Just doing my duty, Ma'am. No need for returning any Favors." she salutes and walks away, before undyne could walk far, mira shouts "T-thank you Big Sister", upon hearing she suddenly felt a nostalgic memory rushing back, but she chose to ignore and walks back to her station.

Upon arriving back it seems to be less crowded than before, looks like every monsters are making their way safe to Hotlands just in time. "Boss, are you okay?" a comrade of Knight asks her. 

"Y-yes I'm fine, whats the situation?" she stutters.

"You sound rather... tired, do you need to take a rest? I can take handle this"

"I'm fine, I just helped a lost kid get back with her mother"

"Alright suit yourself"

"Please focus on your duty, we need to be vigilant in case the threat passes by us" she sat down for a while, her comrade standing on guard with barricades on the way "we can't let our people down"

"We know, take a break there for a while"

"pff... fine suit yourself soldier" she lets out a sigh, removes her helmet, places it on the table beside her and splashes a bottle of water at her face that gives her a refresh. She looks above while her back rests on the chair, closes her eyes a bit and suddenly felt another shiver in her scales, an ominous aura getting stronger and stronger, brings back her pace and see's Sans standing in-front of her "AH!!" she fell down backwards from where she's sitting.

"u-uhh... Und you good?"

"BONES! Why are you not saying anything and just appearing out of thin air"

"I've... been here talking with your comrades, they said you needed to rest for a bit so I didn't bother you"

"what?"

"I said 'I've been here' fish"

"yeah I heard you first" she clears her ears and quickly notices the sharp sounds of a cleaver getting dragged on the floor as it gets near "whats that?" a small figure walking, holding a the said cleaver filled with blood of the monsters she slained on her right hand and a splash of blood on her left cheeks.

"My my... I'm quite lost, can any of you help me?" her comrades raises their weapon "STOP RIGHT THERE!" shouts as their voices tremble with a tremendous scary aura "Aww... am I not invited? What a pity..." she slashes the cleaver horizontally and sends a wave breaking the barriers, pushing the soilders down as Undyne wears her helmet and stands up "Sans." she summons her weapon

"y-yeah?" trembling voice as he looks at the figure in the dark

"I need you to take care of our people while I handle this one."

"Will you be fine?"

"I will. Trust in me. Now go. Our first priority is our Citizens."

Sans in fear snaps his finger and disappears in thin air as she brings her focus back to the figure in the dark, confused she looked around wondering where did it go when suddenly... SHIINGG WOOSH her comrade beside her sliced in half, blood splatters as its body gets pushed back, lower half kneels down flat on the floor continues to bleed.

Some of her Comrades started trembling and shouted in fear tries to run away, however as fast as lightning and Undyne's sight, she then heard another SHIINGG multiple times around her, she turned around instantly and fear comes to her as the sight of the area becomes a pool of blood. Her comrades sliced in multiple pieces barely even recognizable as she starts to contemplate her life choices whether what she is doing, standing there was right or if she felt so coward.

She then heard one of her last comrades that talked to her earlier fell down on the ground, trembling voice asking to spare his life suddenly the figure raises its Cleaver preparing to slice him in half was halted by Undyne as she disappears from her position and appears so fast, faster than the figure pushes back the figure away hitting the farthest wall sending in a huge crater.

"RUN" Undyne said as she reaches for his hand, stands up and runs away however when she looked at the huge crater of the wall the figure was gone and as she turns back she see's her comrade's head sliding off of his neck, body falls down on the ground and bleeds.

"Do you think you can really let someone go?" the figure's giggle echoes around the room as Undyne stood up and focuses where it could be hiding, she felt weak, helpless, and disappointed of herself for not being able to protect her comrades. But it wasn't the time to feel negativity, so she stood up waiting for the figure to attack.

"Giving up already? giggles" the figure appears from behind using her shadows and tries to attack her, however before she could even stab Undyne a spear from above zaps through like a lightning to her body and screams of pain "AARGHHH WHAT CHEAP TACTIC"

Undyne stood there, not moving a muscle, was able to pull that off "What... did we ever do to you..."

A electrocuted figure on the ground behind her tries to stand however before it could even do, she looked at where Undyne's standing and surprised to see she's nowhere, she looked around wondering where she could have went when suddenly Whistles "Up here, you little sh-" floating from above her, with a thundering spear on her hand drops at the speed of light pinning down the figure on the floor shocks her continuously, However while this happen, a faint determination different from the figure she senses.

          「 * You called for Help... 」

Sensing this, Undyne got distracted. The power of the attack gets less damaging slowly and the figure took this chance and pushed her away. "Nice job, Frisk." panting fast, hands in chest, grins sinisterly the possessed spirit said.

          「 * ... But no one responded. 」

"what...?" In Undyne's mind, she felt sudden confusion, but she ignores this. When she's about so speed tackle the Human, it suddenly glitches its appearance and switches to Frisk. "S-STOP!" she screamed, almost getting pierced with the spear, Undyne stops. Her clothes' appearance changed from Bloody Green to Grey.

"who are you...?"

"P-Please spare me... you got to help me... Sobs"

"No... You killed my comrades! RAAHHH!!" she raises her spear again and is about to attack but was stopped again by her "P-PLEASE! You got to listen to me..."

She looks at the helpless child, wondering what to do, it got her confused. She wanted to know more, but then again feels the need to avenge her Comrades. Contemplates for a few seconds and was able to get into a conclusion. As soon as the spear disappears, she was ready to talk to her, however the appearance of its clothes glitches back to green, a Cleaver spawns on her right hand and... SHIINNGG!
