This issue is the last in the arc, and is superb. The writing and artwork are top notch, and the symbolism is everything that one would expect from Millennium.
In this installment, Frank Black and Fox Mulder confront Lucy Butler in Frank’s old house in Seattle. Lucy is the feminine incarnation of Legion, the embodiment of evil. The return to the yellow house symbolizes Frank entering the deeper aspects of his psyche to face his inner demons. Lucy represents both Frank’s personal demons, as well as the amalgamation of evil as it exists on the cosmic level.
Structurally, the story draws on the symbols of divine cycles. There are circles within circles, all representative of the various cycles of spiritual growth and decay, of good and evil, of divine and profane.
The closing lines of this graphic novel sum everything up nicely, and I don’t feel that including the quote here will spoil the ending, because everything is just one eternal cycle.
True good and evil never die, Frank. They just lay low for a bit, lick their wounds, and wait for the cycle to start again… for an entire millennium, if necessary…
