Enzo has taken over the Diner with signs pointing to Enzo's Overwrite Delivery Service. His first customer is Megabyte, who wants Enzo to deliver a package to Hexadecimal. The contents are a surprise.
Dot and Bob are in a storeroom on the lower level where Bob uses Glitch to mend a tear. (The tear is a green glowy globe that moves through walls and causes destruction to pieces of Mainframe.) Just as the tear is mended, Enzo walks in announcing his first customer. He accidentally lets on that it is going to Hexadecimal, whereupon Bob and Dot figure it is probably a bomb. Glitch's x-ray function shows it to be a mask with a clock in it, not a bomb. Dot refuses to let Enzo go to Hexadecimal's place in Lost Angles (too dangerous) and gets Bob to deliver the package instead.
Hexadecimal is in her lair, trying on her various masks, when Scuzzy reports that Megabyte is having Enzo deliver a DELETE command masqued as a mask.
Lost Angles is shown to be a dreary island, connected to the rest of Mainframe by a creepy looking bridge. As Bob flys his zipboard through one arch, he is magically transported to another arch heading another direction. "Why do I always get lost in Lost Angles?", he asks. He gets surrounded by a pack of Nulls (shapeless, worm like critters) and yells at them to find someone else's energy to eat. This is when Hexadecimal opens up a hole in the ground and brings him in. She refuses delivery, slaps the mask on Bob, and sends him flying in the direction of Megabyte's place. (The time-delayed DELETE command has been activated.) Enzo overhears HD gloating, and rushes to get Dot to warn Bob.
They almost catch up to Bob when an incoming game descends on the city. Bob jumps into the game, and Dot drags Enzo in as well. The game is Formula-1. The first lap has racing cars, complete with a nitro boost; the second level has hovercraft doing a slalom through a mine field; the third level is low-flying jet planes going through tunnels and loop-de-loop. Dot tries to get Bob's attention by driving a gasoline tanker truck onto the raceway.
Bob ejects in time, but the blast has caused game corruption, resulting in an infinite DATA/ELSE-IF loop. The implosion starts sucking in everything from the game. Bob saves a binome from being sucked in, and everyone ends up safely outside when the game cube implodes.
Enzo appologizes for not "copying and pasting the truth". Megabyte tells Enzo he's fired, which is just fine with the young sprite. Of course the replacements that MB has to deliver the next bomb are Hack and Slash. They return, with the bomb, stating that Hex says she already has one. Kaboom!
