"Dipper please it's me."
"Prove it!"
Dipper Pines loved his sister he really did, but the creature facing him wasn't Mabel.
"You wouldn't shoot me Dip'n Dots." It said with a smile on a face that looked so much like his sisters.
When It's statement was met with silence, It's smiling face turned into a worried one.
"Right?" It questioned. "You do trust me right bro bro?
Dipper didn't let go of the memory gun. "Take off the sunglasses or I'll shoot!"
"Ok, Ok just put down the gun and I'll take off the glasses, deal?"
"No!" The gun started to glow. It takes a step back with It's hands up in surrender. "Wait!"
"What?!"
"Let's not do anything reckless."
Dipper lowers his gun to look at it, "I'm sorry Mabel." He raises his gun and his sister's body collapses.
The gun fires on the cold cement and soon clatters to the ground. Dipper grabs her and makes sure she's breathing. When she starts to stir, he quickly grabs her wrist in case he has been tricked.
"Dipper it's me," her voice is shaky, but Cipher is a master of deception.
"I believe you; just let me take off you sunglasses."
With one hand he holds her wrists with the other he removes the glasses. She doesn't struggle but he doesn't loosen her grip. When he's met with circular pupils like his own with no trace of yellow, he lets go.
"I'm so sorry bro bro." She says while hugging him there are tears streaming down his cheeks. "I was a dumdum." Dipper doesn't reply he just hugs her back.
"Would you have shot me?" This question makes Dipper tense, but he answers,
"No, never, I would never shoot you, I'm just glad Bill didn't call my bluff."
"You're the best bro bro."
"Thanks."
