Enzo is feeling along since there are no sprites his age in Mainframe. Dot won't let him enter games with Bob and Frisket comes and goes has he pleases. So when a game cube drops on the Diner and he runs to a young female sprite named AndrAIa, he's all too quick to make friends with her. But there's something Enzo doesn't seem to realise about AndrAIa...

The infected Megabyte merges with Hexadecimal, turning into the energy devouring super-virus Gigabyte. It must be stopped before it gathers enough power to create a portal to the Net.

Daemon finally infects all of Mainframe except for Little Enzo, Hack, Slash, and Frisket, who were in a game cube. Hexadecimal makes the ultimate sacrifice.

The two Bobs try to figure out which is the original and which is the copy. Dot can't decide which one to choose. A game cube drops placing Matrix, Frisket, and Normal Bob into a Pokémon style game.

Dot prepares for her wedding with Normal Bob, Glitch Bob remains comatose in the super computer, and Glitch finally reveals the identity of the real Bob.

Megabyte, now able to shift form, rampages through mainframe, but Bob insists his theories on turning a virus good will work.
