Marlene and the two elders immediately made the question that has been bothering them from the very beginning, what's the history of Milo's family, because from their point of view they are traitors.
But they don't have records of ever serving anyone, in fact that's why they escaped from the Clear Water kingdom, because they didn't want to be used, so they can't imagine their ancestors working for someone that could go as far as to curse them like this.
Milo wanted to tell the glorified version of the history of his clan, but under Daimon's cold gaze, he didn't dare to do so and instead told the truth, of which he only knows a part, because despite him having more than one thousand years of age, he is the youngest in his family.
Naturally after hearing that, the elders and Marlene wanted to give Milo a beating, their clan members can only dream of ever reaching the age of that guy after all.
