Series creator and writer Brian Wood followed up "Friendly Fire", the heaviest story to this point, with the breath of fresh air that is these six character examination issues. Don't let that turn of phrase fool you, though. While these issues do step away from Matty, Zee, and their never ending quest to find meaning and justice in a war zone, they have no less depth. Art, poverty, greed, emotional detachment, culture, spiritual transformation--they're all here, playing out in a war zone. And removed from Matty (mostly), these stories can be told without having to advance a larger narrative of how the DMZ is being changed by the presence of the ersatz journalist main character.
The following contains spoilers for DMZ 23-28.
"Decade Later"
Issue 12 pulled the curtain back from the DMZ and revealed the city's rich, developing culture. Among the characters introduced was Decade Later a middle aged tagger who grew up in New York City and couldn't be chased out by war. The issue opens with Decade braving sniper fire to get across the street and break into a hardware store, his goal to acquire all the spray paint he can. From there the story cuts between the present, the start of the war, and before the war. Based on what we're shown of the past Decade has been a tagger forever, but he's never been interested in just leaving behind "some boring tag" or claiming territory. He wants to share knowledge. He wants people to find his work ten years from now and take meaning from it (that turns out to be the origin of his tag). The remaining scenes from the past show Decade working on an unspecified project having to do with New York subway cars.
