Reason  is still  up top,  its monitor  screen  radiating
   blue  static toward  heaven.  Hiro finds  the hard  power
   switch  and turns it  off.  Computers  this powerful  are
   supposed  to  shut  themselves  down, after  you've asked
   them to.  Turning one  off with  the hard  switch is like
   lulling someone to sleep by severing their spinal column.
