Once Stan had rushed into the portal, the electric beams ceased and the portal appeared to have shut off. Dipper and Mabel cried out, "No! Stan!" and they both attempted to turn the portal back on, to no avail. They didn't know how to activate it. "Maybe, we should switch some switches and press some buttons?" Mabel suggested, reaching out to a switch. Dipper slapped her hand away. "No! What if accidentally switching something on could kill him?" Mabel looked at her twin brother in shock. Then they both turned to the portal.

All they could do right now was wait for Grunkle Stan to return.

Dematerializing was painful.

Stan felt every single one of his body cells vanishing. And it took a while for him to finish dematerializing, too. Thoughts ran through his mind as the pain eventually subsided, and his whole body turned numb. He knew that it was a bad idea to rush into the portal like that, without everyone from the Bill Cipher wheel. A laugh echoed around him- a laugh he knew. Bill.

"Ah, Stan Pines, it's good to see yo-..." A pause. Stan could visibly see his body again, and in front of him was the dream demon. A glowing yellow pyramid with a top hat and bowtie. "You're not Stan Pines," Bill grumbled. Stan gave him a confused look. "Uh, yes I am," he protested. "No no no," Bill sighed, "You're Stanford Pines. I'm looking for Stanley Pines." Stan's expression switched from confusion to fury- "You're not going to get my brother! He's my brother!" Stan ranted, jumping at Bill, trying to grab him, but Bill dematerialized and rematerialized behind him. Stan turned to Bill. "I've spent years and years trying to perfect the portal to find my brother and I will! You'll see!"

A hole appeared behind Stan, and before Bill could reply, Stanford Pines was sucked into another dimension.

He was standing in front of the Mystery Shack. The S was still gone. Did the portal work at all?

Stan peeked through the window, and to his surprise, he saw Lil' Gideon and Pacifica playing chess with Robbie. He was about to yell at them until he realized that they didn't behave or dress like themselves. Instead of a prissy blue suit, Gideon was wearing what it looks like Dipper should wear, and instead of snobby rich girl clothes, Pacifica was wearing a 90's-styled outfit, and Robbie was wearing a white collared shirt and slacks. What? Stan furrowed his brow and craned his neck. Soos was still the same. And Buddy Gleeful was there too- was he the owner of the Shack? Where was his own counterpart in this dimension? Stan wondered, pacing away from the Shack.

Then he stopped in his tracks and his eyes widened.

Where was Mabel and Dipper?
