You woke with a start, an odd noise filling your ears. You quickly descended the shack stairs and pulled open the front door. It looked to be around 1am. Ford stood outside, his form a dark silhouette against the white, full moon's light.
"What was that noise?" you asked.
There was another loud wheezing which echoed through the night.
"I'm.. not sure," he muttered. You noticed he held a few devices and wore a headset.
You stood in silence, a light flashing in the corner of your eye. Soon, a blue telephone box appeared and a tall man with messy brown hair stumbled out, coughing and wheezing, waving a hand in front of his face as smoke poured out of the large blue box behind him. He wore a brown pinstripe suit which happened to match his expressive chocolate brown eyes. His eyes were wide and staring at the two of you. Well, not you, but the shack behind you.
"Is that the Mystery Shack?" He asked, sounding utterly bewildered. Ford looked shocked, staring at the man and his blue box. The man dashed back inside his box, and before you knew it, Ford had shed his headphones and dropped his devices, chasing the man into his box. You followed, not sure how they both fit in.
"This isn't right.." The man from earlier muttered "This isn't my universe.."
"Are you with Bill?" Ford demanded, a stern look on his face.
The man looked confused "Bill? Like.. Bill Cipher? From Gravity falls?"
It was Ford's turn to look confused. He didn't get a chance to speak before the man spoke again.
"I never watched a lot of TV, but I remember this show," he mumbled, running his hand through his messy hair "You're Ford Pines!" he suddenly exclaimed. Ford looked confused. "How do you know my name?" Ford demanded.
The two of them talked and you sort of zoned out, looking around the man's box. It was huge on the inside. You ran your hands along the console looking thing with the bunch of buttons
"Hey!" The man exclaimed, grabbing your shoulder and spinning you around "Don't touch that."
