We just do not think about that which lies between buildings, at least, most people do not. I have photographed an inordinate number of scenes where a building has been removed to display what was. The result is often a shadow, a remnant that remains despite its absence.
In this particular case it appears that a lifeline was sent out, and rejected, resulting in a connection to nothing, dividing itself.
