Things have gone wrong now...

When the shark-like in their lairs have no respite from the giant rending claws you know it's not going to be good day, depending on where you're standing of course. Concrete packed securely by the ton above your head usually offers a strong sense of security. However when it is gouged and shattered, it rapidly surrenders that security. What was was once a strength now becomes an intolerable weakness. Lurking is never a good thing and perhaps this climatic end is the inevitable reward for adhering to that strategy.
