"Undyne!" Mettaton called, looking for the fish monster. How could he have forgotten not to leave her alone? He went into Undyne's room to look for her. "There you are!" He said. Undyne was in her closet, trying to climb up to get her container of art supplies. Mettaton quickly picked up Undyne and tucked her into bed. "You can play later. For now, it's nap time," he said. Undyne pouted and crossed her arms. Mettaton sighed and picked her up. He tried his best to rock her, trying to get her to sleep before Alphys got into trouble. It didn't take long until Undyne was fast asleep, drooling on Mettaton's shoulder. Mettaton tucked her into bed and then quickly went back to the kitchen. To his surprise, Alphys was still there, waiting for him. She crawled to him and reached for him, smiling. "Hey Alphy," Mettaton said, picking Alphys up. Alphys giggled and put a hand on Mettaton's nose. Mettaton smiled. "Do you think you can take a nap for me, darling?" He asked, hoping to have a break. Alphys pouted. "Please Alphy?" Mettaton said, rocking Alphys. Alphys shook her head. Although her eyes looked tired. It didn't take long until she was fast asleep on Mettaton's shoulder. Mettaton tucked the tiny scientist into her bed, before heading to the living room. He sat on the couch and sighed.
Flowey sat in the kitchen flower pot, looking out the window. He sighed. Boredom was normal for him, as being a flower meant little entertainment. His thoughts were interrupted when a squeal of joy come from behind him. He groaned, knowing exactly who it was. He turned around to see Toriel climbing up to the kitchen counter. She pulled herself onto the counter and crawled to Flowey. "Go away goat," Flowey said, annoyed. Toriel hugged him, giggling. Flowey groaned. "Get off of me!" He yelled. Toriel just giggled, drooling on him. Flowey sighed and went to the attic flower pot. He grabbed a small bottle of purple liquid, and went to the living room pot. "Hey Scrap Metal!" he yelled at Mettaton. "I got something for you!" He shouted, tossing the bottle to Mettaton.
"What's this?" Mettaton asked, looking at the bottle.
"It's the cure for this whole mess, you idiot," Flowey said. "Fix the goat and the others. This has gotten more annoying that entertaining." Mettaton sighed and went to Toriel. He opened the bottle and grabbed a dropper. He opened Toriel's mouth and dropped a few drops of the cure down her throat. Toriel blinked a few times, then looked up at Mettaton.
"W-Wha? What happened?" She asked, confused.
"I'll explain later," Mettaton said, curing Sans and Papyrus. He then cured Undyne and Alphys. Then he finally cured Frisk. Then, after explaining what happened to everyone, he sat on the couch. Alphys crawled into the room and climbed onto the couch.
"M-Mettaton. The cure that you used only cured our minds, not our bodies," she said, quietly. Mettaton sighed.
"It's better than nothing, darling," he said.
"B-But that's not i-it," Alphys said, stammering. "W-With Frisk being a human, the cure won't a-actually work on h-her..."
"Well, at least you have your mind back, darling," Mettaton said, patting Alphys's head. "That means you can work on the cure for your body." Alphys thought for a second before looking at Mettaton.
"T-That's what I wanted to talk to you about," she said, s-shyly.
"What about it, darling?" Mettaton asked.
"W-Well… n-never mind," Alphys replied, looking down.
"Mettaton, deary, can you come here please?" Muffet called from the kitchen.
"Oh, I'll be back Alphy," Mettaton said, before going to the kitchen. Alphys thought to herself for a few minutes. Then she hopped off the couch, and headed down to the lab. She looked on the shelves for a certain serum. She located and grabbed a bottle of light pink liquid off of the shelf. This particular serum was the same regression serum that had fallen on Frisk. This was the serum that started this all. Alphys gathered up a few other ingredients, and started to mix a few things. Just then, Mettaton came down the stairs. "Hey Alphy, what're you doing?" He asked, seeing her working.
"O-Oh. I-I'm just trying to t-tweak the cure s-so it can f-fix our bodies too," Alphys lied.
"Oh, well, do you have any more of the regression serum left?" He asked. Alphys nodded and grabbed another bottle from the shelf. It was filled with the same liquid she was working with. She handed it to Mettaton. "Thank you, darling," Mettaton said, smiling.
"W-What do you need it for anyways?" Alphys asked, curious.
"Oh, no reason. I just want to put it s-some place where no one will mess with it," Mettaton lied, then he went back upstairs. Alphys let out a sigh of relief. She then continued to work. After mixing a few more ingredients, she grabbed a piece of paper and a pencil. After writing something on the paper, she folded it up and wrote the letters "MTT" on the front. She put it in her lab coat pocket. She then carefully picked the newly mixed serum up. It was a light purple in color and it carried the slight scent of baby powder. She looked at the note in her pocket and sighed. "I-I'm s-sorry Mettaton… I just need some time…" She said to herself, before drinking the serum. "O-Okay… That should g-give me two w-weeks," she said, before she set the empty test tube down and went upstairs. Mettaton was sitting on the couch in the living room. Alphys climbed up and sat next to him.
"So, did you find a way to fix your bodies?" Mettaton asked, hopeful.
"N-No…" Alphys said.
"You will eventually, darling. I know you will," Mettaton said, hugging Alphys.
"Y-Yeah… e-eventually…" Alphys said, uneasily.
"Are you alright, darling?" Mettaton asked, noticing the tone in her voice.
"Y-Yeah…" Alphys lied, not wanting him to find out what she had done. She yawned, feeling slightly tired still.
"How about you take a nap, Alphy?" Mettaton asked, picking her up. Alphys nodded and started to fall asleep. Mettaton took her to her room and tucked her into bed. "And now to visit a little flower," He said to himself, walking towards Flowey's room with the regression serum clutched in his hand.
