Memories.

Where are the knifes...?

Y...you... really hate me that much?

If you keep going the way you are now...

Now I see who I was protecting...

You're gonna have a bad time.

Listen. I have a plan to become all powerful. Let's destroy everything in this wretched world...

Not you... But them!

The child awoke with a start. They were lying in a bed of flowers. They couldn't remember where they had come from. All they remembered was the mountain, and... something about a knife? They couldn't remember. All they knew is that they were scared, and they wanted to leave the place they were in, and go home. They stood up, and walked down a narrow, cavernous hallway. It opened up into a room, with an illuminated patch of grass. As the child approached it, a flower bloomed suddenly. It was as big as the child, and unnerved him.
"Howdy!" It said, with a face coming out of nowhere. "I'm Flowey. Flowey the- Oh. It's YOU." The child looked at him quizzically. "What, you didn't get enough last time? Felt like doing it all over?" The child continued to stand there, unsure of what to do. "...Oh?" Suddenly, something in Flowey's mind clicked. "You don't remember anything, do you?" Suddenly, his mouth turned into a large grin. "He he heh... Well then. I'm not gonna stop you. Enjoy, psychopath." He disappeared into the ground, leaving no trace of his existance. The child stood there, unsure of what happened. Before they could make another move, a figure approached from ahead. Toriel looked at the child, a look of sadness and pity in her eyes.
"Oh... child, are you alright? Are you hurt?" She asked. The child was silent. Something about this goat woman was familiar, yet it was impossible for the child to know from where. They had never seen such a thing in their life. And yet...
"Come with me. I'll take you back to my house."

After a short walk, where Toriel showed the child how to operate the traps in the ruins, and how to avoid combat, the pair arrived at Toriel's home.
"I can't explain why, my child, but I changed my mind earlier. I was originally going to leave you by yourself to prepare a surprise for you. Something changed my mind. Like somewhere in my mind, something was telling me that leaving you by yourself would be a bad idea. I cannot fathom why." Toriel explained to the child. The child had been having similar thoughts, about what would have happened. It was as if they were trying to block the memory of something. The child put it behind them. It was probably just their nerves. "Anyway, here we are. Come inside, I'll show you around." Toriel walked into the house. The child followed. It was a small house, but it was surprisingly cosy for its location. "Come with me. I'll show you your room." She walked east, and the child continued to follow. They came to a stop in front of a door. "You can stay in here." said Toriel, as she ran her fingers though the child's hair. "Well, I should probably get going. Go inside and look around!" She said, and hurried off. The child proceeded into the room. It was made for a child, but the child had not seen any other children. The child walked over to the bed, and lied down in it. It was comfy. The child had not realised how tired they had been. Maybe just a few minutes.

Sounds strange, but before all this, I thought we could be friends. I always thought the anomaly was doing this because they were unhappy, and that when they got what they wanted, they would stop all this. And maybe all they needed was, I don't know. Some good friends, some nice food, some bad laughs. But that's ridiculous, right? Yeah, you're the type of person who won't ever be happy. You'll keep consuming timelines over and over until, well... Hey. Take it from me, kid. Someday you gotta learn when to QUIT. And that day's TODAY.

The child awoke with a start. They were soaked in sweat. The room was dark, the light having been turned off earlier. But the child REMEMBERED. Every evil thing they had done. Everyone they had murdered. How it had all started with the words from Flowey. Kill or be killed. Seeing Chara, and managing to get away somehow. The first. Toriel. TORIEL. The child suddenly realised that they had been in the house of Toriel for quite some time, and could have easily...
The child ran out into the hallway, and darted into the living room. Thankfully, Toriel was still there, unharmed.
"Are you alright, child? Did you have a nightmare? Come here, and I'll comfort you." said Toriel. The child's eyes widened. If they went near Toriel, they would kill her. They ran back, into the hallway. Luckily, the child knew where to leave, from... past experiences. They ran downstairs, through the tunnel and through the door out of the ruins. "Child! Come back! It is dangerous out there!" The child did not stop. They ran through the snow, over the bridge. "Someone, please, stop that child!" The child looked behind them. Toriel was hurriedly trying to catch up. Suddenly, they ran into something hard. The child fell back, dazed. They looked at what had stopped them. Standing there, in front of the child, was a skeleton, in a weird costume. They tried to get up, but couldn't. They remembered this skeleton too. They also remembered gaining their trust, and then killing them in a single blow. The child heard Toriel's footsteps get closer, and started to drift out of consciousness. The last thing they heard was the excited voice of someone, who was familiar, yet they didn't know. "Sans! Look! I finally caught a human!"

When the child started to stir for the first time, they overheard an argument.
"But we need to take him to King Asgore! He told us to bring him a human's soul so-"
"Listen to me, skeleton. Though it pains me to say it, I am still your damn queen. So you will ignore your orders, and take this sick child to the royal scientist, no matter what your superior may say!"
"My name's Papyrus, you know. And my superior's Undyne."
"Fine then, Papyrus. You and your brother will accompany me to the royal scientist's lab. If we meet Undyne along the way, make it seem as if we are taking the child to Asgore eventually. I don't trust the royal guard." The child then fell back into unconsciousness.

When they next stirred, two new voices had shown up.
"I still don't understand how taking this child to be medically treated is necessary."

"That's because the child isn't going to Asgore. Toriel wants to keep the child herself."
"What?! How did you-"
"I was watching you. Don't worry. I'm fully on board, otherwise you would have had a lot more resistance."
"I still don't see why we aren't taking him to Asgore. Surely you could find another human child on the surface?"
"NO. I refuse to let Asgore's ridiculous plan happen. Even if I have to combat him myself."
"Well, I'm definitely with you. This kid seems like a nice person." That voice! The child tried to get away from where it came from.
"They're moving! Quick, help me hold them still!" The child felt cold metal pervade their skin, and then drifted off again.
