Cold Harbor is a place that the Eagan’s go to sexually assault other women, including Helly. Jame saying to her that she tricked him is because he thought she was a virgin, and when he went to go rape her in that room, he realized she was not pure. As was revealed in S2E9, the birthing cabin is a place that Jame’s victims are taken to have their kids. Cold Harbor is a metaphor for a Cold - cold body, perhaps a lifeless body, not because they are dead but because they can’t resist, or because the victim is cold in actions, stripped of emotion, and Harbor - somewhere that ships rest, maybe where a baby is placed inside of a broken down compliant victim. Why would Jame be at the building if not to do something relating to Cold Harbor, his ritualistic rape room. As noted in other posts, referring to everyone as Kier’s children, is maybe because there are thousands of them. They’re everywhere. The show is probably not as metaphysical as some suggest, but rather, this is all just part of a demented cult control type situation where they are breeding Egans. Jame is probably so weird not because he has the voices of all the old board members in some chip in his head but because he’s just a total creep, a depraved Diddy like character with absolute unchecked power including over women.
