Our heroes return home to a devastated Mainframe. Buildings are in ruin, tears are appearing all over the sectors, and the Principal Office is over run by Viral Binomes. After a happy reunion with Dot and Mouse, Bob and Dot’s feelings for one another are put on hold as the group learns about what has transpired while they were away. Megabyte has firm control over Mainframe and his power grip is slowly pulling the city to pieces. Whilst Bob tries to come to terms with what’s happened since he’s left, Dot is unsure of how to express her feelings to him, after believing for so long that he was lost to her.
