When Zillah asks if he's stupid enough to think that he'll be able to recognize his own wife, Zillah says that he isn't stupid enough. He's a "thing," which means that he can be bought and sold. He doesn't care what Zillah thinks of him, he just wants an opportunity to choose the person he wants to marry. Zillah wants to know if he can keep his marriage or get a divorce tomorrow.
