Hedda is crazy. Who do u know plays with pistols when they are bored? Not many i know. She is very dangerous while with these pistols. This is why she has so much power with them because everyone fears her while she has them, not knowing if she would shoot at any moment or not. But, without the pistols, she is nothing to be feared. This can play into why Judge Brack is able to take control of Hedda.
