Found
a neat little article from KNR about the Greenlandic youths at the gala. Apparently Angititaq Motzfeldt, who was seated at Frederik's table, had met Frederik years back in Narsaq. The article gets Victoria and Mary mixed up (I suspect he just referred to Victoria as "the Crown Princess"

) but Motzfeldt says that Victoria told him she is very fond of Greenland and would like to show the country to Estelle one day.
