Another day at Gravity Falls. Mabel and Dipper were helping out at the Shack, just like usual. Just an usual day.
Usual for Gravity Falls.
Seus entered through the front door.
"Has anyone seen Mr. Pines?
"I think he's in his office. Why do you ask?" Dipper asked.
"This weird girl is trying to steal the S from the sign in the roof."
"Who is stealing what!?" Stan appeared out of nowhere, startled by the thought of someone not paying. He stomped his way out to the front yard, ready to fight for his possessions.
This young girl with two curled ponytails, a long dark cape and a worried look was standing in the roof of the Mystery Shack, Holding the S tightly.
"Hey your little thief! Put it back where it was!"" Stan shouted to her.
"If you don't want the whole city to be flooded, then I'll have to take it." She casually responded, and jumped off to the ground, almost floating with her cape.
"Now, if you excuse me." She was leaving, but Stan didn't let her, taking the wood letter back by force.
"If you want it, you'll have to pay!" He made it clear.
Her eyes changed from a neutral calmness to a mysterious anger in a silent frown.
"Fine!" She gave up. "If the whole city drowns tomorrow, blame yourself, greedy old man!" And she left to the woods.
Only Dipper saw the next scene, as everyone entered the shack already: following the strange girl with his eyes, he saw her take a wand from her cape. Muttering some inaudible words, she disappeared into dust, leaving Dipper rather confused and scared. After a moment of thoughts, he finally realized why:
"That girl is a witch!"
