But since it's a case of life and death, Bruce didn't believe anybody poisoned wouldn't be willing to check things out after hearing word that Bruce could cure poisons, so his last speculation was that little to nobody got poisoned over the days.
Meanwhile apart from Violet Bane, Bruce had already formulated antidotes for over 50 poisons which he had some patients with a bit of influence get for treating them of their respective injuries.
