The door of the machine was only partly open, so only Frisk could squeeze through the gap.
As soon as they had gotten out, blue strings latched onto Frisk's soul, lifting them into the air.
As the strings wrapped more tightly, Frisk found it harder to breathe.
"Well, well, well. What do we have here." The Sans muttered. Frisk turned to face them.
The Sans was different than any Frisk had ever seen before. Sans' bones were black instead of white, around them was floating words, all saying "ERROR", and he was wearing red glasses.
Frisk could feel their HP drain. They were starting to black out due to the lack of oxygen.
The door to the time machine was kicked open, and Papyrus fell out onto the ground.
"So you've finally found me. It only took ya quite a while." ErrorSans said.
"What are you talking about?" Papyrus queried.
"Don't yo-", Error began, before bones flew over his head, severing the links to Frisk's soul.
Frisk was barely conscious, but crawled back into the machine, where Gaster lay recovering, as he was still on low HP.
Error and Papyrus turned around, to see Underswap!Sans running fast.
"Brother?" He called out.
"Sans!" Papyrus replied.
The two brothers pulled each other into a massive hug. Gaster was fiddling with the buttons.
"I've missed you so much! How did you end up here?" Papyrus asked.
"Well, I-" Sans began, before a sharp pain was felt in his stomach.
Papyrus looked down, to see that a sharp bone had impaled both him and his brother.
The world began to turn black for Papyrus, his head becoming light. He turned to his brother.
The blood was running from the wound, a little coming out of his mouth, He looked up to his big brother, and smiled.
"We... we'll be together f-forever... brother." Sans said, pulling his brother into a tighter hug.
As Gaster watched the two brothers turned to dust, he flipped the switch.
"Do you actually think I can get my soul back?" Flowey asked.
"WHY OF COURSE! ONLY I, THE GREAT PAPYRUS CAN TRULY CONJOUR SUCH IDEAS." Papyrus shouted.
"You said it bro." Sans panted, running out of breath.
Sans' magic, like the owner usually is, is on break. The four friends are running to Alphys' lab.
"Are you actually tired already? We haven't even entered the cave." Chara joked.
"Haha, real funny. I'm sure you don't get tired?" Sans asked.
"Not at all. Try and keep up!" Chara laughed, running off into Waterfall.
"NYEH! FULL STEAM AHEAD!" Papyrus boomed, sprinting after the human.
"Oh the little... put me down Sans." Flowey demanded.
Sans released the flower pot, letting it hit the ground. Flowey went underground, and soon it was Sans alone, who promptly lay down and fell asleep.
Some time later.
Undyne was worried. Papyrus wasn't at his house, and he wasn't answering any calls.
She was frightened a human hada came and killed her best friend. Sans wasn't anywhere to be seen.
As she entered waterfall, her boot met something.
"Ow! What the f-, oh. Heya Undyne." A familiar, deep voice said at her feet.
Undyne nearly jumped out of her skin. "What the-. Oh, it's just you. Have you seen Papyrus? I'm starting to get worried."
"Oh yeah. He ran ahead with the hu-, our friend." Sans corrected,
"Did you just say human?" Undyne asked.
"Uh, did I? I must of been mistaken." Sans nervously said.
Undyne grabbed both sides of Sans' jacket. "Listen, bonehead. If you don't take me to the human, you can kiss your job goodbye."
"Whoa, hey, easy on the jacket. Alright, fine, but you won't lay a hand on them. Got it?" Sans questuoned.
"Of course I'll kill them. What are you gonna-" Undyne began, before Sans grabbed her hand, and in the blink of an eye, they were at the entrance to Hotland.
"Holy... how did you?" She began, before Sans simply shrugged, and said "Shortcut."
Chara ran out of Hotland on top of Papyrus' shoulder, squealing with glee. Their smile faded when they caught site of Undyne. Papyrus' smile widened.
"AH, HELLO UNDYNE! HOW ARE YOU?" Papyrus beamed.
"I, uh..." Undyne began, seeing Sans eerily stare her down with a lack of pupils. She was extremely nervous, and afraid of Sans.
"Good! And I see you've... captured a human which I will not touch at all!" She nervously said, much to Sans' amusement.
Flowey came out of the ground, visibly exhausted.
"Can you guys.. wait... for ONE MINUTE." He panted.
Undyne eyed him, before turning to Sans.
"So where are you heading?" She asked.
"We're heading to Alphys' lab, if you wanna come." Sans said.
Undyne's eyes narrowed. "How would you know Alphys?"
Sans reached into the left pocket of his shorts and took out a badge. "Official Royal Scientist Assistant."
Undyne's jaw dropped. She had no idea Sans and Alphys worked together. Papyrus and Chara were equally amazed. Flowey, however, was not.
"Yeah, yeah, it's obvious, but can we move? I can't wait for much longer!" Flowey shouted, eager to regain his true form.
