Colonel Robert E. Lee is offered the opportunity to lead the Union army and the position of Major General. He respectfully declines because his home, Virginia, is considering a secession from the Union, and he feels he has no greater duty than to serve his home.
The residents of Sensible Flats have no more water in their resevoir and are trying to discover why the water levels have declined. The CyberSquad asks for historical records of the water level, and Rudy provides records of the last 25 days to the group. Inez, Matt, and Jackie think about how to use the dates to tell a story and decide that graphing the water levels day-by-day would work. The CyberSquad creates a line graph on the side of the tank and explains how to read the graph to the residents.
The CyberSquad speaks with Deke about the declining water levels in the lake. He brings them to his shed, where he shows them a line graph of the water level each day. He states that the lake will dry up in four days if it doesn't rain soon. He illustrates how he used the line graph to detect a pattern and predict the future.
