Insanity or Normality ? BillDip ?

It had been a few weeks and so far many things have been happening around Gravity Falls.
Ford was now staying in the lab, probably because Stan doesn't trust him anymore after-

After the incident.

Wendy and Soos have gone to their normal, working, and Wendy is now going to college finally having enough money to afford one. Stan and Soos still ran the mystery shack.
And Mabel. Well Mabel was in her room with another demon.
( a few weeks ago )
"Who are you!?" Ford yelled as the gun was still pointing at Wendy.
"I am Samm. Samm Cipher."
Ford's eyes widened and pointed his gun towards the woman.
She moved her hand and the gun flew out of Ford's grasp.
Ford starred at the demon in shock, "how-how is their another one? Another one of you?!"
The blonde demon just starred at the old man.
"Your brother, he thought that his summoning of my brother didn't work. It did, but he was summoned out of Gravity Falls. As he kept trying he kept summoning more, more Ciphers, from different times, different worlds, different universes."
Ford starred at Stan.
"This is your fault!!"
Stan looked down, he hoped that was the last time he would have to hear that coming from him.
"Sadly it isn't."
Ford looked at the blonde.
"He has done nothing but try to bring back a good man in my opinion, yes, Bill was a-a crazy bastard, but he changed when he came back home."
Sam walked up to Ford, "whatever changed him, this person deserves him, and Bill deserves this person."
Ford was just looking between Samm and Stan.
Samm was startled when she saw the brown haired girl giggling.
"He's fine. The boy he changed him? My brother. Dipper. He's safe. And he ran. With another demon. Killian."
Samm's eyes widened.
"What is that gremlin doing here in this time? Or in this universe. That summoning circle shouldn't have brought him back in time, how could that-" Mabel just starred at the girl as she was mumbling.
Mabel tensed when she felt someone lift her up from her shirt, "Where did those demons go!" Mabel just starred at Ford, Samm simply tapped him on the head and down he fell.
"Now child, I must know where my idiotic bastard of a brother is, Mother wants to meet my brother-in-law.
Mabel was just starring at Ford, and looked back up at Samm, "Im sorry I don't know where they went, I just know they went somewhere but here."
Samm looked down at the old man, a frown appearing in her face, Mabel felt hands on her shoulder and jumped away. She saw her Grunkle Stan putting his hands up.
"Sorry kid, thought you just need reassurance."
Mabel nodded, and looked back at Samm who was now crouching and poking at Ford.
"What are you doing?"
Samm looked up and looked back down, "Trying to see if he's a suitable vessel, so far his muscular strength seems alright, his mind on the other hand," she knocked on his head hearing metal, "seems a bit harder to access."
Mabel looked back up, a million ideas running through their head,

"What if I'm your vessel?"
