Underfalls (Gravity Falls/Undertale Crossover) DISCONTINUED

Chapter 5

A/N Sorry if stuff Frisk and Chara do something stupid. I'm trying.

"So are you two twins? You look like it." Mabel said. Frisk and Chara sent glances at each other. They were both had the same idea.

"Yeah, we are." Chara said, giving Dipper a look that said 'go along with it.' Mabel made a humming sound.

They walked into the Mystery Shack and Frisk instinctively grabbed Chara's arm.

"Hey dorks. Hey other dorks I've never met." The girl at the register said. "Undyne..." Frisk whispered. "She reminds me of her." Frisk whispered the sentence do quietly that only Chara could hear. Chara just patted Frisk on the arm.

"Hi Wendy! These are our new friends Chara and Frisk." Mabel exclaimed. Frisk smiled and waved while Chara gave a small 'hi' and looked at the shelves on the other side of the store part of the shack. Chara kinda felt guilty because Wendy also reminded them of Undyne.

"We're going to go to our room now. Bye Wendy!" Mabel said and dragged everyone upstairs.

"So do you guys like boy bands?" Mabel asked. Chara shook their head while Frisk shrugged. "The only music I can recall was a music box tune." Frisk said. "Hey do you guys have bathroom?"

"Its over here, follow me." Dipper mumbled.

The fact that you are with good friends fills you with determination.

Energy fully restored

Frisk LV 1 Health 20 ???

Frisk came out of the bathroom to see the trio waiting for them. "Hey Chara can you come in her for a sec, I need to talk to you privately."

"Okay..." Chara replied.

Frisk pulled Chara into the bathroom. "I want to tell them about you-know-what."

"What?! I don't want them to do something stupid. What if they can't handle it?" Chara said. "Their not exactly Sans, Frisk. They probably won't remember if we do that."

"I know. That's why I SAVED. I can RESET if they can't handle it." Frisk whispered so quietly it was almost inaudible. "Plus I believe that at least Dipper would believe us, he already knows about what you are." Chara sighed and moved out of the way for Frisk to go out and tell them. "Y'know, Frisk your quick at changing your mind." Chara mumbled. Frisk just smiled and left the bathroom to see the two siblings listening in.

"How much did you two hear?" Frisk asked.

"Only bits about us not being able to handle something. What can't we handle? We're the mystery twins!" Mabel yelled.

"Keep it down! Only about five people know what I'm going to tell you two. You probably won't remember anyway." Frisk mumbled. "Let's go to your room for this. C'mon Chara." The for made their way to the twins room.

"This isn't a good idea." Chara spat. Frisk gave a look that said 'I know.'

"Okay so Dipper, remember when I showed you that picture. The one with the monsters and me in the middle? I never showed you this part of it." Frisk took out the picture and pointed to a flower looking at the camera with a smile that a maniac would give. "That's Flowey. He had a power before I before I fell into Undertale (Chara dubbed home that name for where we need to be.) The power was unwillingly given to me when I fell. The power was the power to RESET timelines. I could do things like kill a ant, RESET and the ant would be alive and I would have never killed it." Frisk explained.
"Its hard to explain to someone who is a scientist for this subject or have the power."

"The reason we have this power is because we have the most determination. My friend, Sans, kinda hates me now. He knows about the power and hates when I RESET. This time I had a good reason." Frisk finished, and glared at Chara.

"Hey, are you going to tell them what we did, Partner?" Chara said, angrily.

"Chara you're scaring me." Frisk said, quivering. "You said you would stop."

"And you said you would erase everything and go to the next." Chara's eyes turned from their normal brown into red. Frisk hugged Chara and kept whispering things like 'calm down.'

Eventually, Chara's episode died down. Chara hugged Frisk back and kept saying 'I'm sorry' even though Frisk forgave them.

"Hey, Chara, remember when I RESET and we were in 'undersawp'? It was hilarious seeing Sans act like papy. Or when we were in underfell? That was a scary adventure." Frisk said, attempting to make Chara laugh. Then they had an idea. "I never knew underswap Mettaton could be so ghostly."

Frisk kept making jokes to make Chara laugh and when everything was calmed down Mabel said "Okay can someone explain why Chara's eyes went red and why they got all scary?!" Frisk sighed.

"Please don't be afraid of Chara after I tell you, they're changing as much as I can make. I'm determined to change their ways." Frisk started. "Chara, ya see, Chara is a demon. And we are kinda fused together." Frisk finished off.

"A-a demon? Like Bill?" Mabel asked. Frisk shrugged.

"Anyway we have to go, we-" Chara started but was cut off by a crash.
