Chapter 1: A Loss of Trust
Toriel Dreemurr was facing a conundrum.
Earlier this morning, she was pleasantly surprised when another human child fell into the Underground.
The old woman fed the child and gave them a place to sleep, before making plans to permanently adopt them into her household.
However, Toriel was not happy when the child asked for permission to leave the Ruins.
Thinking quickly, she rushed downstairs to block the exit to Snowdin Forest.
Next, she stubbornly commanded the child to pick between two narrow-minded choices.
"Attack me or run away!"
And then the child immediately inflicted a serious wound with a toy knife, bringing the caretaker to her knees.
"Do you really hate me that much…?" Toriel rasped.
After seeing the old woman's pitiful state, Frisk rolled his eyes before walking around her.
As the young boy placed his hands on the familiar door to Snowdin Forest, Toriel spoke up again.
"… Please don't leave, my child-"
"I'M NOT YOUR CHILD!" Frisk shouted, stunning the goat woman into silence. "And you're not my mother. I already have a mother, and you aren't her."
Upon hearing this rejection, tears began to well up in Toriel's eyes, and Frisk scowled.
"You were going to try and scare me into staying down here with you forever, and you were going to use your fire magic to do it. So why should I feel sorry for someone like you!?"
Noticing that his hands were shaking with rage, the child took a deep breath.
For the record, I don't hate you, but I don't trust you, either."
Unsurprisingly, this did little to comfort the goat woman.
"You gave me food and a place to sleep, but that doesn't give you the right to control me or my life. I trusted you, and you betrayed that trust."
After finishing his rant, Frisk turned around, pushed the door open and walked outside.
Once she had processed what just happened, Toriel wearily dragged herself to her feet, and slowly pursued the young child.
Cowardly woman or not, never let it be said that Toriel Dreemurr was a quitter.
