All of the “bus metas” we’ve seen so far on #TheFlash have had some axe to grind, and except for Ralph, whom the team got to first, they’ve each set out to avenge that wrong using their powers. They’ve become villains largely because of *how* they chose to attack the problem (i.e. by attacking people).
Did the Thinker, in addition to arranging the incident, pre-select *who* he wanted to be on that bus? If so, how much was for experimentation & how much for his master plan?
