In her 2011 book '' Into the Looking Glass : Exploring the Worlds of Fringe '' , author Sarah Clarke Stuart found parallels between the episode and the 2011 Tōhoku earthquake and tsunami , which occurred several weeks after " 6B " aired . Items of comparison included the " cracks " in the universe and shifting tectonic plates , and the " vortex " and the tsunami swallowing up entire villages . Clarke Stuart noted that " because of its destabilizing character , the natural world is often depicted as the antagonist in science fiction and adventure narratives " like '' Fringe ''
