"Encrypt?" Lynn asked, confused, "What's he talking about Dipper?"

"You didn't tell her?" Ford asked.

"I thought it would be safer that way," replied Dipper.

"Yet you told this boy," Ford reminded Dipper.

"He...sort of found out on his own."

"What's that supposed to mean?"

"Bill can turn into a human in this dimension."

"Bill?" Lynn asked, "Like, Leni's boyfriend?" Dipper and Lincoln nodded.

"That was Bill!?" Mabel yelled.

"Wait," she said as she pushed Dipper, Lincoln, and Mabel, "You knew Mabel!?"

"We'll tell you everything in due time," said Dipper, "but right now you have to trust us." Lynn looked hesitant, however she started to understand.

"You'll tell me everything, right Dipper?"

"I promise," promised Dipper. Lynn nodded and Dipper smiled. Ford pulled on a book on his bookshelf. The shelf moved itself away from all else, revealing a secret elevator. Ford led the children into the elevator and pushed the middle button. The elevator moved down two floors. When the door opened, Dipper looked at their surroundings.

"Great uncle Ford," he said, feeling a sense of familiarity, "This looks like your private study."

"I'm aware of that Dipper," Ford replied, "I'll admit, it's a little unnerving coming back here." He led the kids to the memory-encryption device he had previously attempted to use on Dipper over the summer. "Okay, who's first?" he asked.

"I am," said Lynn as she sat down. Ford put a helmet on her, and started to encrypt her thoughts. The screen on the back displayed her thoughts.

"What are they hiding from me?" It read, "This almost feels like a football helmet. Sports, sports, sports, sports,"Lynn's thoughts had finished being encrypted. Without a word, she took the helmet off and stood up. Dipper silently walked over and took the helmet from Lynn, placed it on his head, and sat down.

"I'm sorry Lynn," the screen read as it scanned Dipper's thoughts, "I have to tell her. I have to warn her. I want her to be safe." A few minutes later, Dipper's thoughts were fully encrypted. This machine was certainly faster than the last one. Next up was Mabel, but rather than sitting through that, Dipper took Lynn's wrist and led her upstairs. Once there, they sat down.

"Okay," started Lynn, "What are you hiding?"

"Okay," Dipper exhaled deeply, "Your sister's boyfriend, the one you just met?" Lynn nodded, "He's actually an inter-dimensional omni-god. Well, right now he's more like a dream demon-"

"Dipper!" Lynn slapped him, "Get to the point!"

"William Decode is not who he seems. He's actually known as Bill Cipher, one of the most dangerous beings in the universe. We stopped him before, but that wasn't the same Bill."

"What?"

"Look Lynn, Mabel and I are from another dimension where we defeated Bill."

"Then why are you here?"

"We were told that another Bill—this Bill—is scheming to resurrect the Bill from my dimension."

"So you're not gonna stay?"

"I don't know yet."

"Hey Dipper?"

"Yeah?"

"If you aren't planning on staying, then you can at least tell me your first name."

"Fine," Dipper gave in. If he truly cared about her, than he would tell her, "My real name is Mason Pines," he confessed.

"What?" She laughed.

"Everyone back home just calls me Dipper," he revealed.

"Thanks Dip," she said. They sat in silence for an hour, before Lynn spoke up. "Should we tell Leni?"

"I don't think that's a good idea," he said. He thought logically about the situation. "I have a feeling that 'William Decode' won't be around for that long." A few minutes later, Ford, Mabel, and Lincoln arose from the elevator. As they walked into the room, Dipper and Lynn shared a fist bump. Lynn stood up. Dipper, Mabel, and Ford stood and waved as Lincoln and Lynn left.

"Dipper," Lincoln said as she threw him a walkie-talkie. "Take this, just in case."

"Thanks," he yelled.

"See you tomorrow!" Lynn yelled to the twins.

"See ya!" They yelled back. Ford closed the door.

"Well Dipper," Ford said sternly.

"Great uncle Ford I-" Ford cut Dipper off.

"I understand that it's not your fault. Bill disguised himself as a human and snuck his way into those kids' family." Ford said, understandingly, "However, their safety lies in your hands. I trust that you can keep those two safe."

"I can do it great uncle Ford," Dipper said in an assuring tone. Ford nodded.

"Now get some rest you two," Ford said before sending them to bed.
