"Does anybody really want Murphy's Law Weaponized?" Zack Underwood asked pointedly.

"Murphy's Law got me Artificially Inseminated to avoid a Time Paradox, I'm voting no." Melissa Chase stated knowingly.

"I'm unfortunately, voting yes. The Future Needs Murphy's Law Weaponized Against Bill Cipher, I also Promised Phineas that I would help him in exchange for them keeping my memories intact." Milo Murphy explained.

"Why were our memories erased if Milo gets to keep his?" Sara Murphy asked.

"I think Phineas and Ferb wanted to make sure that Bill Cipher never discovered their plans against him." Milo Murphy explained.

"Did Phineas and Ferb really tell us their plans against Bill Cipher before they erased our memories?" Melissa Chase asked suspiciously.

"They wanted me to memorize their Time Travel Blueprints for them." Milo Murphy pointed out.

"So basically, the only person who knows how to Defeat Bill Cipher is Milo Murphy. I'm feeling very nervous and paranoid right now." Zack Underwood admits truthfully.

"Yeah, Murphy's Law being the only threat towards Bill Cipher does sound really suicidal." Sara Murphy agreed.

"I think Phineas and Ferb thought Melissa being pregnant would help us avoid the Time Baby sending the Time Police after us." Milo Murphy says thoughtfully while everyone listened.

"Why was this Artificial Insemination done without her consent?" Sara Murphy asked suspiciously.

"The Melissa Chase from the future was already working for the American Government, nobody wanted to risk losing her if our Melissa died because of the Time Paradox happening." Milo Murphy explained.

"Wait a minute, I was at risk of dying from this Time Paradox happening?" Melissa Chase asked suddenly.

"Technically, you would have been killed without Murphy's Law causing this pregnancy. I think this Forced Artificial Insemination prevented my parents from getting killed in the same Traffic Accident." Milo Murphy explained nervously.

"A Traffic Accident? Murphy's Law Caused Forced Artificial Insemination because we almost died from some Traffic Accident?" Melissa Chase demanded.

"The Fireside Girls believe that someone came from the future to kill us and the Artificial Insemination ruined their plans." Milo Murphy admits sheepishly while Melissa Chase looked at him suspiciously.

"So being pregnant is their Contingency Plan for keeping me alive?" Melissa Chase asked.

"Unfortunately, Murphy's Law is not a rational phenomenon, anything that can go wrong, will go wrong." Milo Murphy pointed out helpfully.

"I'm a Pregnant Teenager being hunted by Time Travel Assassins, how can Murphy's Law make this situation any worse?" Melissa Chase asked Milo Murphy rhetorically.

"Is that me?" Sara Murphy asked worriedly.

"I think we accidentally got sent ten years into the past." Zack Underwood stated knowingly.

"So, driving home is out of the question?" Sara Murphy asked knowingly.

"We don't want another Time Paradox happening! I'm already pregnant, I'm not risking anything else going wrong today!" Melissa Chase started shouting.

"She has a point." Milo's Mother agreed.

"Drive towards Gravity Falls, the Northwest Family are going to be collecting the Dragon Balls there!" Milo Murphy proclaimed.

"Milo is right, we can use the Dragon Balls to wish ourselves home!" Zack Underwood declared.

"Don't worry Melissa, we are all in this together!" Milo Murphy proclaimed.
