As I understand it, the conflict took place between Stella and Belle. The essence of the conflict is not clear to me. Apparently Irma tried to extinguish the conflict. She says that Belle knows the weak point of Stella (touchiness, susceptibility, sensitivity, quick temper) and beats there. Irma says that Stella knows perfectly well how drunk Belle behaves and that it can not be stopped.Apparently, Stella in warm blood (rashly) was offended on Irma. Irma says that she did not say anything to Stella, but only held her hand.
