This is the mid story of Dipper and Mabel when they got dropped off by Bill in Chapter 4. Dipper is figuring out something of who Bill actually is.

"That was a fun ride with Bill wasn't it," Mabel said as she closes the door behind him.

"No it wasn't for me Mabel," Dipper said as he was angry as usual.

"Bro-bro you shouldn't have come with us then," Mabel said staring at Dipper looking away from her.

Dipper stares at the ground and was thinking, "do you remember almost three years ago when Bill Cipher was about to kill us in his hands."

"How would I not forget about that Dipper. It was the best summer of our lives," she said.

"I was concerned for your life. Even though we don't hang out as much anymore. I am still scared now and days about you being trapped with Bill's bubble. His world that he created for you," Dipper said, "and since we have an humanoid that is from another dimension coming out our doorstep asking you for a ride around town."

"Dipper... we met tons of beings from other dimensions and timelines," Mabel said, "the Bill driving with us is no better than any other person from any other world. So give him a chance."

"I don't think that is simple, Mabel. The tattoos that Ford engraved in my arms a year ago shows that any person or beings from different dimensions who is a follower to Bill Cipher. Do you think Bill Cipher might return. However for the past few month since we met this "Bill" my tattoos we glowing and burning like crazy."

"Do you ask Great Grunkle Ford about this?" Mabel asked.

"No I haven't yet because he is still travel with Grunkle Stan," Dipper said, "they're busy right now."

"Oh I forgot about that." Mabel said.

"Just still be friends with Bill for a while till I figure who he really is." Dipper said.

"But that would hurt him Dipper. You can't do that as well because it would hurt his feelings about you," Mabel said.

"Well I guess that would have to do considering that he could be our enemy or even worst that Bill could actually Bill Cipher," Dipper put his hand on his chin, "If he is Bill Cipher why did he recognized us at all."

"Amnesia, he has amnesia Dipper," Mabel said.

"That would make sense considering that Ford used the mind eraser to destroy Stan's mind with him. That would made him stop remembering about his past trouble."

"But Dipper...he's a good guy. He did not hurt anyone yet," Mabel said.

"Just look after yourself okay," Dipper said.

Then Dipper's cellphone started ringing. He answered quickly as it might be Ford contacting him about his adventures with Stan.

"Hello?"

"Hello is this Dipper Pines..."

"Yes?"

"This is a patient here in the hospital who was recently in a car crash and this piece of paper of your name and number on it."

"What?" he turns toward Mabel, "you gave Bill my number."

"Sorry I had to," she said, "who is that?"

"The hospital...someone says that this person has the number and blood stains...oh god no. That is the one chance that Bill might be alive or not would our only lead if that man stays alive in the hospital. Lets go now!"

"Dipper wait!" Mabel said as they both started leaving the house again.
