Watching Manousos try and talk some sense into Carol is absolutely heartbreaking. He's saying all the things she already said! She spent the first part of the show desperately trying to make someone understand. No one saw her way. Then, slowly, the hive got under her skin. The hive systematically broke her down into a dependent shell of herself. She compromised all her principles. Talking with Manousos like talking with a version of her that never entered this abusive relationship. A narrative mirror she has to look at and be forced to remember what she believes. She resists his attempts to reason with the reality of her situation, as victims usually do. Carol pushes away the person who is being direct with her, the only person left on earth who can understand her, for a hivemind that wishes to assimilate her. What also strikes me as interesting is that Manousos seems to pretty quickly piece together exactly what's happening here. He sees Helen's tombstone. He talks with "Zosia". He is smart. He can tell this is some sort of abusive relationship where the hive is feigning personhood to gain her submission. He tells her "Do you want to save the world, or do you want to get the girl?" He is firm, and direct. She won't hear it. It was so hard to watch how accurate it is to watch someone in an abusive relationship try and be reasoned with and then push away the person trying to help them.
