Treblinka became real, the shift from myth to reality took place in a blindingflash, the encounter between a name and a place wiped out everything I had learned, forced me to start again from scratch.
Whereas some heroes in this series appear to be listening to their emotions and willfully blinding themselves to the truth, Flash is able to step back and analyze the situation.
Unless you're super close to the lip of the stage (in which case you're blinding the poor theremin player with your insistent flash), those shots you keep pumping out can't be that good.
