Game of Thrones Season 6 Episode 06 Blood of My Blood
WHEN DROGON LANDED, DAENERYS RIDES ON HIS BACK AND PROCEEDS TO RALLY THE DOTHRAKI BY STATING THAT SHE CHOOSES THEM ALL TO BE HER BLOODRIDERS, RATHER THAN THE TRADITIONAL THREE CHOSEN BY KHALS. SHE THEN ASKS IF THEY WILL CROSS THE SEA WITH HER AND GIVE HER THE SEVEN KINGDOMS, WHICH THEY UNANIMOUSLY AGREE TO DO.
DAENERYS: Every Khal who ever lived chose three blood riders to fight beside him and guard his way, but I am not a Khal. I will not choose three blood riders. I choose you all. I will ask more of you than any Khal has ever asked of his Khalasar. Will you ride the wooden horses across the black salt sea? Will you kill my enemies in their iron suits and tear down their stone houses? Will you give me the Seven Kingdoms, the gift Khal Drogo promised me, before the Mother of Mountains? Are you with me, now and always?
