History Recap / FamilyGuyS9E16TheBigPangTheory

* PreMortemOneLiner: "Hey, Bertram, what's your favorite kind of bottled water? Mine's arrowhead."

* TheCameo: When Brian and Stewie are floating in the void, they somehow come upon a giant ad promoting ''Series/TheClevelandShow''.

* AssholeVictim: Bertram

* WorthIt: Bertram says it before killing Da Vinci.

When Stewie obtains his plutonium to power the return pad, Bertram learns of the time machine and sneaks into the Griffin house to kill Stewie's ancestor in order to prevent him from ever being born. Unfortunately, as Stewie and Brian discover, by preventing the former from being born, then Stewie would not have been able to start the Big Bang, thereby creating a paradox that begins to wipe everything from existence. Stewie explains this to Brian and says that they will have only one shot at getting back to the present since Bertram took the return pad with him. Brian and Stewie then go back to fifteen minutes before Bertram arrives in the past to stop him from killing Stewie's ancestor, revealed to be Leonardo da Vinci. Stewie guesses that given that he and Bertram have the same father but different mothers, Leornado da Vinci must be an ancestor from Lois's side of the family or else Bertram would be erasing himself as well if he killed Leonardo da Vinci. When Bertram arrives in the past, he throws a knife at Leonardo da Vinci, forcing Stewie to block the attack. Stewie then tries to kill Bertram with the knife but Bertram hits Stewie before he could do so. He then uses Leonardo's winged flying machine to fly away. Since Stewie needs the return pad to get back to the present, he uses Leonardo's ornithoper to chase Bertram, and ends up battling in midair with him. Stewie shots a magnetic missile at Bertram but he jumps out of Leonardo da Vinci's invention and activates his parachute so he can safely fall to the ground. Bertram takes a crossbow and has Stewie, Brian, and Leonardo at a crossbow point. Stewie tells Bertram that he created the universe and that if he is erased, the entire universe will disappear forever. But Bertram says that to him, erasing Stewie is worth destroying the universe and shoots Leonardo in the chest with a crossbow. In rage, Stewie shoots Bertram in the chest and head with the same crossbow, killing him.

Tropes related to the episode:

* WhatHappenedToTheMouse: We didn't see what happened to Leonardo's body, but it can be assumed that Stewie buried it somewhere.

* KickTheDog: Bertram killing Leonardo Da Vinci

* ApocalyspeHow: Class X-4. Had Bertram killed Leonardo Da Vinci, Stewie would never be born, thus the whole universe would've been erased.

* AssholeVictim

Despite the fact that Leonardo is dead, the universe is still existing. Stewie then concludes that he must be his own ancestor. He sends Brian back to the present, where a letter from the Holy See Vatican arrives, detailing that Stewie has buried himself in a cryogenic tube underneath the Griffin household. Once he is unearthed and thawed, Stewie informs Brian he put his DNA into a syringe and injected it into Leonardo's girlfriend (multiple times). Stewie brings back a candle from Leonardo's time, leaving Brian (who would have rather had him bring back one of Leonardo's original notebooks) annoyed.
