Third person POV

"The one and only kid" Bill said as he appeared I front of the three kids making them jump back.

"B-bill?! BUT Y-YOUR DEAD!" dipper screamed.

"Well that's what you meatsacks thought. I'm not that easy to get rid of kid." Bill replied as twirled his cane.

"HOW TF ARE YOU A HOOMAN?!" Cassandra screamed

"Oh right, this is why I came to look for you kids since I literally got no one to go to." Bill said casually.

"Why?" Mabel asked as she squints her eyes at bill with suspicion.

"Because I wanted to make a deal." Bill said.

"Oh hell no, were not making a deal with you cipher!" Dipper said as he glared angrily at bill.

"You didn't even hear me out yet." Bill pouted.

"No even if we do hear you out I bet-"

"Let's hear him out guys."

"WHAT!" Mabel and dipper screamed.

"Thank you!" Bill exclaimed because he didn't want to deal with the twin's (dipper) whining.

Dipper POV

Is. she. CRAZY?! like what the heck Cass?!

Me and mabel just stare at here with shock in our face. She wanted to hear out bill's condition let alone make a deal with him.

"Okay, but first you need to turn the world back to normal meaning, bring back the quacking colors man!" Cassandra complained.

The three of us look at her confused.

"Quacking?" We questioned

"What? You want me to curse for real?" she said looking at us while we just shrugged.

Not long after we hear bill snapping his fingers, making the world go back to normal. Cassandra suddenly grabbed bill's hand and went to a nearby cafe. Surprisingly bill just followed and struggle or even say anything.

"Uh, cass why are we going inside the cafe?" I questioned as we followed her.

"Cause I'm taking him on a date." Cassandra said (Sarcasm)

"What?!" Me and Mabel yelled

"Relax I was just being sarcastic." She said as we get in a booth and sit down.

bill was across from us staring at us (That is creepy) while I loomed over at Cassandra to see that she was thinking about something. A waitress came and tried to take an order but Cass only shooed her away.

"So what's the deal about bill?" Cassandra said in a serious tone.

"Well since I'm stuck in this meatsack form I might as well learn how to live like you humans." Bill said

"That's it?" Mabel said

"What? You humans need to do alot of things in order to survive." Bill retorted.

"Well bill does have a point and plus his just a human now." Cassandra said shrugging.

"But, I am still a demon."

"Then you can just use your magic. Simple" Cassandra said as she flopped her head down.

"You really want me to use magic. Don't forget kid were not in gravity falls anymore so I can easily do something you don't want me to do." Bill said well more like threatened.

"Touché" Cassandra said

"But why do you want to learn on how to live like a human?" I said to bill

"Good question Pinetree, and here is my answer. You see I already tried on taking over your dimension which failed but then while I was trapped in the mind scape I had alot of time to think about it and then it came that 'if I take over the dimension it's gonna be boring since everything will go on how I want it and there won't be any challenges'. So that my dear Pinetree is why I want to live like you meatsacks." bill finished and we just nod.

"Okay so we help you learn on how to live like a human and so in return you won't hurt anyone and you will protect our family and friends. Deal?" Cassandra said

"Sure thing kid." Bill reached his hand out to seal the deal.

"Okay, dipper you shake it." Cassandra said as she retrieved her hand.

"WHAT?" I screamed catching everyone else's attention and I just muttered a sorry and went back to sit
"But your the one who wanted to do the deal."

"Fine."

Cassandra shook bill's hand and both hands were immediately set on blue fire, though it looked like it doesn't hurt seeing as cass's expression was calm. But the fire quickly disappeared so no one saw it except for us.

"Alright the deal sealed. But first you need somewhere to stay." Cassandra said as she stood up with us following.

"Well we can't just let him stay at our house, we don't really have enough room plus we don't really want a roommate." I said as I pushed the door open and we all got out th cafe.

"Hm, fine will talk about this when we get to your house." Cassandra said as we all headed home.

When we finally got there we started discussing about bill.

"Alright bill first of all-"

The four them discussed on what bill can do and not do.

                       5 hours later

"And then I'm like 'OMG! IM AN ANIME!' and then I got my head out to check out another bubble." Cassandra was telling us about her dipping her head in the weirdness bubble during wierdmaggedon.

"Cass, why would you do that?"
I asked

"Because dipper that's what you do when you are bored and is in the middle of a apocalyptic setting." Cassandra said.

                  Third person POV

"HAHA, i like this kid. She's got guts."
Bill said as he pat Cassandra in the back.

It's been five hours since they got to the pines residence and Cassandra and Bill are already acting like best friends.
"That's because I was bored Bill."

"Well your the first ever human I've seen doing that." Bill said

"I'll take that as a compliment thank you very much." Cassandra said as she cross her arms and turn around in a sassy way.

That made them all laugh including bill. After that they spent hours talking and watching movies till they fell asleep.

The end. :3

Welp that wraps up our story.
