Dimensional Location: Unknown Gravity Falls Universe During World War Two.

"Rick Sanchez, is this your Portal Gun?" Bill Cipher asked with amusement.

"Give me that!" Rick Sanchez yelled in sudden outrage.

"Jerry Smith, I found your Missing Wallet too!" Bill Cipher proclaimed next.

"Impossible, my Wallet is right... that is my Wallet!" Jerry Smith declared after checking his pockets for it.

"Summer Smith, I got you Dennis the Rabbit, he needs a good home and I hear good things about you." Bill Cipher tells her.

"Is this an Animal Agent Trained by Major Monogram's Organization?" Rick Sanchez asked suspiciously.

"Dennis the Rabbit Loves Carrots." Bill Cipher evaded the question.

"Did you Blackmail Dennis the Rabbit into protecting my family?" Rick Sanchez asked Bill Cipher suspiciously.

"I might have given Dennis the Rabbit all the Access Codes to Doctor Heinz Doofenshmirtz's Computers for when you seek into his Apartment Building." Bill Cipher admits truthfully.

"Why would I sneak into Doctor Heinz Doofenshmirtz's Computers?" Rick Sanchez asked Bill Cipher suspiciously.

"Doctor Heinz Doofenshmirtz still has your Portal Gun Blueprints, remember what having your Portal Gun Blueprints can do in the wrong hands?" Bill Cipher gloats back knowingly.

"Thank you for reminding me." Rick Sanchez tells Bill Cipher suspiciously.

"No problem, I want your Portal Gun Blueprints destroyed just as badly as you do." Bill Cipher admits truthfully.

"I wonder why my Portal Gun Blueprints ended up inside Danville in the first place." Rick Sanchez tells Bill Cipher suspiciously.

"It seems like the Future Rick Sanchez was making friends with Lovemuffin inside Danville because he wanted something... I wonder what it was." Bill Cipher answers back thoughtfully.

"You know something." Rick Sanchez told Bill Cipher pointedly.

"All I know is the Time Baby asked the Future Rick Sanchez to get something inside Danville and then somebody killed him to steal it for themselves." Bill Cipher explained.
