At the end of the mission "The Family Jewel" Marcus asks you to hand him over the hard drive with GenIVIV on it since he has "some use" for it.
While you're on your way BALEX also mentions that you should install her into a "Toilet or even better, a broken toilet so she can't do any harm" and Marcus just responds with "Ah! I know just the place!"
So obviously Marcus has the AI and he has plans for her but what exactly does he do with her?
I've completed the mission multiple times and I've searched the entire ship but I haven't found anything.
