It is a purely mechanical, automatic reassignment based on raw stats, not choice.
Princess Donut declares it unacceptable and threatens to leave if Carl renames the party, asking whether he wants Mongo to come from a broken home. Carl promises to keep the names and titles for now. He notes that a few floors earlier this would have genuinely wounded her, and that her outrage is now mostly performance — which quietly saddens him.
