Dimensional Location: Gravity Falls inside the Animated Ghostbusters Universe.

"The Gravity Falls Hospital where the Ghostbusters are staying is still running on their own Emergency Power Generators." Stanford Pines explained.

"At least Gravity Falls is still paranoid enough to have Backup Generators." Stanley Pines remarked in amusement.

"Unfortunately, the whole town does not have enough Backup Generators for anywhere besides the Local Hospital." Stanford Pines interrupted his Twin Brother pointedly.

"So the Ghostbusters will be fine, but, Gravity Falls has been thrown back into the Pioneer Days without Electricity? Any Ideas how to Restore Electricity to Gravity Falls?" Stanley Pines asked hopefully.

"I'm Sending Electricity from the Mystery Shack's Power Grid to the rest of Gravity Falls, I think we have a Nuclear Reactor down inside the Missile Silo that needs investigating." Stanford Pines responds worriedly.

"Just as I thought... we don't need Fuel for the Dimensional Portal because this Nuclear Reactor is maintaining it. We just need the Computer Access Codes to activate it without Starting World War Three simultaneously." Stanford Pines explained.

"This Portal Room was constructed during World War Two because the Alternate Stanford Pines went into the past with Natalie Northwest." Stanford Pines says after Reading McGucket's Handwritten Notes in complete disbelief.

"This says that Natalie Northwest asked for my help stopping a Bad Time Agent from changing history, McGucket got a Letter explaining how this Portal works after I disappeared. McGucket must have the Computer Access Codes that we need." Stanford Pines explained.
