@Lucykaede1 u r rite that Helen's son didn't & cudn't bcum samarat of India as he was half greek & chanyakya never wanted this bcoz of them being foreigner & he only let CGM marry helen 4 diplomatic reasons just like many Kings in the past Indaian or oders did!!
and though they r showing dhurdhara as dhananad's daughter but not all historians agree on this. sum say CGM did marry dhananads daughter but dhurdhara was not his daughter.and even CGM only overthrown Nanada empire & didn't kill dhanaand & he let him go 2 jubgle 2 lead a life of ascetic!! and at that time dhananad let her daughter(dhurdhara was sum oder princess sum say she was princess of Kaushambi) marry CGM!!😊
