Will the real Bob please step forward? There might not be a virus, but life's still interesting in Mainframe when a second Bob comes on the scene. No one knows which is which - including the two Bobs. With wedding preparations underway, Dot can't decide who to marry and turns to her friends for assistance. Meanwhile, an old enemy returns to the system and only one of the Sprites can save the Mainframe inhabitants.
