Ok let's set the record here, Eternal Mangekyo Sharingan has only been obtained by Madara Uchiha by taking his brothers eyes, Sasuke and Itachi perforemd susano'o with Mangekyo Sharingan! not Eternal, however sasuke will now possess the EMS in future episodes unlocking new abilities and strengthening his old. SO NO ITACHI NEVER HAD EMS BECAUSE HE NEVER SHOWED EMS,AND SASUKE PERFORMED SUSANOO WITHOUT EMS! EMS requires you and your brother to both possess Mangekyo and for one to remove the others and take them, so in no conceivable way could Itachi have had EMS, especially since he said only he and Madara unlocked mangekyo sharingan and if sasuke did he would be the third.aquaglow, understamdable however you are forgetting that itachi murdered the whole uchiha clan, he could have easily taken any one of their eyes.
susanoo requires EMS just like amaterasu. itachi used them both, therefore he had EMS
