Dimensional Location: Gravity Falls Universe, Mystery Shack.

"This is worse than I thought it would be. Dipper's Daughter has Survivor's Guilt and I think that she changed history when the Natalie Northwest Family found everybody dead at the Mystery Shack inside the future!" Stanford Pines proclaimed in alarm.

"You mean that Natalie Northwest went back in time because we designed the Portal to send Dipper's Daughter into the past in the first place?" Stanley Pines asked in sudden realization.

"Exactly! Natalie Northwest used my own Research inside the Mystery Shack and now Bill Cipher is changing tactics to deal with her changing history against him! Ironically that was why the Northwest Family got captured and taken into another dimension where we can't find them!" Stanford Pines explained worriedly.

"So Natalie Northwest went after this Bill Cipher and then the Northwest Family got captured within two days of Natalie Northwest coming to the past." Stanley Pines says following along.

"Yes, but more importantly, the Northwest Portal Recycled the Dimensional Rift Energy and corrected the damage that might have given Bill Cipher his freedom to destroy us. This Portal Design is 20 years more advanced than the one I constructed inside the Mystery Shack beforehand. Natalie Northwest must have brought her own Portal Blueprints from the future to help her rebuild it for herself." Stanford Pines pointed out in amazement.

"Will you just stop drooling over the future technology and figure out where the Northwest Family went already?" Stanley Pines demanded in growing frustration.

"Stanley, please understand how wonderful this new discovery is!" Stanford Pines protested while investigating the Northwest Portal's Technology for himself.

"I would rather talk some sense into Dipper's Daughter about blaming her parents for stranding her inside the past than watch you Reverse Engineer this Northwest Portal Technology." Stanley Pines answers truthfully.
