I just wanna know ask do you guys think Cortana died, I mean I know she told him that they would give him a new AI but I mean really that's Cortana or do you think she is in the forerunner system now and will make a return. One thing I like was when she saved chief the didactic was like you do this humanity and you are wrong and she says I'm not doing it for humanity, cause she was doing for chief. So my question is do y'all think she really died?
