User blog comment:Aleksandr the Great/Prothean Squadmate is Officially DLC/@comment-1331463-20120222144741

Seems pretty pointless to me, I imagined the Prothean would have been a vital part of defeating the Reapers, like he knew some secret about them or something along the lines

I still bet that the key to the game is going to involve some kind of secret plan or superweapon against the Reapers... I just imagined a 50'000 Year old Prothean would have tied in with that.
