 Khal Drogo ( Jason Momoa ) , delirious from an infection caused by the chest wound inflicted by Mago , falls from his saddle , a sign of weakness among the Dothraki . Daenerys takes Drogo into her tent and sends for Mirri Maz <unk> ( Mia Soteriou ) to help him . However , Ser Jorah Mormont advises Daenerys that they should leave now because the Dothraki only respect the physically strong . He explains that , if Drogo dies , Qotho ( Dar Salim ) and the other <unk> will fight amongst themselves to be his successor ; whoever wins will kill her and her unborn child to prevent Drogo 's son from growing up to be a rival . Daenerys refuses to abandon her husband , even when Mirri tells Daenerys that she cannot save him and instead advises giving Drogo a quick , clean death . In desperation , Daenerys encourages Mirri to use blood magic despite Mirri 's warning about the consequences of such a spell , that only death can pay for life . Mirri brings Drogo 's horse into the tent , slits its throat , orders everyone to leave , and warns that none must enter during the spell . Qotho , shocked at what Daenerys has done , tries to stop the spell , but Mormont kills him to prevent interference . Daenerys then goes into premature labor , but none of the Dothraki midwives help her , owing to their belief that she is cursed . In desperation , Mormont carries Daenerys into Drogo 's tent to seek Mirri 's help .
