i'm not really convinved they're going to "join forces," so to speak. you can hear her and gravemind speaking the first line simultaneously, but if you pay close attention, her voice subtly changes for each line spoken, so it's more like she's narrating, i think.
we may indeed find out that cortana's and graveminds immediate goals are the same, or at least similar. with how readily she opened herself up for gravemind's questions at the end of H2, it seems to me that if she does help him in the short term, it's simply to manipulate him in order to make her long term goals possible.
