A flashback to when Mainframe's Twin City was still intact, a late-teenaged Dot oversee the construction of Dot's Diner. A younger Enzo, with a shirt stating "IAM 00" and a puppy Frisket, desperately reminded Dot they will be late for their father's experiment. Dot finally realizes how late she's running and yells to Jimmy to take over the construction and turns to leave. Suddenly, a bright light rises from the Twin City. The light shrinks down into the Twin Cities Principal Office and the building explodes, destroying the entire city. The shockwaves hit Mainframe... Dot suddenly wakes up from her nightmare.
