You were at Gravity Falls Square when suddenly the sky turned red and a huge cross "+" did not appear there, from where Bill Cipher jumped out, now having acquired a material body, although still remaining a triangle, and his henchmen. He let out a crazy laugh.

"THIS PARTY NEVER STOPS! TIME IS DEAD AND MEANING HAS NO MEANING, EXISTENCE IS UPSIDE DOWN AND I REIGN SUPREME! WELCOME ONE AND ALL, TO WEIRDMAGEDDON!"

Out of the ground Fearamid appeared, Weirdmaggedon began... You were about to run, how abruptly you witnessed Stanford firing a cannon at Bill, but... He missed. Perhaps, while the monsters were distracted, you could have escaped, or you could have been senselessly heroic, you already saw how the demon turned Ford into a golden statue.
