[ On the flight from Central City to Gotham, back when Barry had so enthusiastically thrown in with his insane idea, Bruce had done a number of calculations in his head. Not quite gleeful, as he's not the type to be gleeful, but silently laced with a kind of perverse excitement only known to true physics nerds. How fast might Barry move, what kind of fine control he might have to change directions or do complex tasks while moving at speeds that rendered him undetectable to the human eye.
He has considered the word 'vibration' before, in context with the younger man, feeling echoes of it in the air or through the floor after certain movements, noting the faintest unusual blip on a seismic reader in the cave, and later matching the time back to him zipping after them from the batsignal. And, because he is the kind of person to have thirty pairs of recreational handcuffs and an unknowable number of other related items in a penthouse in the city that Alfred doesn't bother him at, he had thought, also, briefly, I Wonder What— ]
