User blog comment:Aleksandr the Great/Prothean Squadmate is Officially DLC/@comment-1440333-20120223192334

The Prothean character was mentioned back in the original leaked story files, but they didnt seem to suggest that the Prothean was a squadmate. What if, and it is a big if, the Prothean was always meant to be on the Normandy in a similar fashion to Joker or EDI, but From Ashes merely makes him a squadmate and adds a mission to elaborate on his backstory?
