Jace breaks down Geiger #2 as the Ghost Machine universe expands with the introduction of Las Vegas, the King, and the idea of the so-called "Holy Grail." The issue builds out the larger world around Tariq Geiger, while also revealing more about his past and the possible connection between his condition and the radiation that changed everything.

The story introduces new characters and shows the harsh reality of survival in this post-apocalyptic setting, while also setting up larger conflicts that continue to pay off later in the series. With the benefit of hindsight, many of the elements introduced here carry more weight, especially when looking at how the narrative evolves beyond this issue.
