6th Chronicle of Macdude

The first two of the three scenes of Act IV are pretty devoid of all imagery, actually, the entire Act is lacking in that territory. I suppose the only themes in the first two scenes are planting and illness. The planting is easy to find, usually has something to do with nature, and the illness is the plague that Macdude is currently making. It was hard to pick the themes out of this because there were SO MANY!
