Dimensional Location: The Gravity Falls Universe where Dipper and Mabel were born during the 1960s.

Earth Year: 1964 AD.

Jerry Stevens checked the Diamonds and the Jewelry he brought back from the future.

He had sold most of it to Buy Bud Gleeful's Construction Company.

The Hidden Fallout Shelters were his only Contingency Plan to get the Gravity Falls Townsfolk out of harm's way.

Jerry Stevens was expecting soldiers from the future to come checking on him.

Jerry needed to show some results before something went wrong and his superiors decided to replace him with someone else that didn't care about Civilians getting killed in the crossfire.

Jerry Stevens frowned, Gravity Falls was being run by Corrupt Police Officers working for the Northwest Family.

Bud Gleeful was running for Mayor against Stan Pines when Jerry Stevens arrived, chaos quickly followed.

"We should steal money from other cities, we have the Cannons!" Stanley Pines Proclaimed.

Mister Jerry Stevens glanced around at everyone cheering for Stan Pines and then the Oregon State Police came after everyone for something.

The Mayor Campaigning quickly fell apart after the Oregon State Police started arresting everybody within sight and Mister Northwest ended up going to Jail for Money Laundering inside Gravity Falls.

Jerry Stevens looked around to clear his head of the bad memories, the Gravity Falls Townsfolk were all hiding from the Riot Police outside.

It was an ironic twist, Bud Gleeful had become Mayor after Stan Pines got himself arrested for Money Laundering at the Northwest Mansion.

How the Northwest Family got their Money Laundering started at the Hidden Gambling Casino inside the Mystery Shack was anyone's guess.

Bud Gleeful had tried to stay out of everyone's way, Gravity Falls was still rebuilding from the last Gang War between the Corduroy Family and the Northwest Family.

The Corduroy Family had tried to run the Northwest Family out of Gravity Falls and the Northwest Family Hired Gangsters to fight back with.

The end result was Wendy Corduroy's Entire Family being sent to Jail.

Bill Cipher thought that he had finally won until another Dream Demon got in his way.

The Inner Doofenshmirtz had sent his own Human Puppet into Gravity Falls from the future.

Bill Cipher frowned when Jerry Stevens arrived and started Building Fallout Shelters everywhere.

"Human Time Travel Technology, I finally get something going my way and this happens, I don't even know what is going on around here now." Bill Cipher admits to himself nervously.

Bill Cipher had pulled Roger Doofenshmirtz between dimensions because he wanted another advantage to exploit when he went against the Mystery Shack Family again.

Roger Doofenshmirtz would eventually go to Jerry Stevens and beg for his help. Predictable behavior would work to Bill Cipher's advantage here. The only problem was the Inner Doofenshmirtz trying to Conquer Gravity Falls before Bill Cipher did and Heinz Doofenshmirtz being killed because Bill Cipher contacted him for help without telling the Inner Doofenshmirtz about it.
