Final answer:
After Kit speaks to O'Hara about the Billow, he is convinced to become an associate editor, write weekly criticism, and pen a serial, all without initial pay.
Step-by-step explanation:
After Kit conveys Gillet's message about the Billow to O'Hara, several events take place. First, Kit becomes an associate editor of the Billow. This is a result of O'Hara's persuasive methods, which include agreeing with Kit's suggestions, firing the inadequate critic, and compelling Kit to stay on board without pay until the Billow becomes financially stable.
Additionally, Kit agrees to write weekly columns of criticism and to produce a weekly installment of ten thousand words on the San Francisco serial. This flurry of events significantly changes Kit's role at the Billow.
