Final answer:
Jonathan held a secret over Rita to prevent her from talking about certain matters, and Lassiter did the same to Jane.
Step-by-step explanation:
In the given passages, the characters Jonathan and Lassiter held secrets over Rita and Jane, respectively, to prevent them from revealing certain information. In the first passage, Lassiter warned Jane about being spied on by her women and advised her to pretend to go somewhere before making a quick move for the door. In the second passage, Jonathan threatened Rita's reputation by spreading gossip about her love for Fay and her religious duty. So, it can be said that both Jonathan and Lassiter used manipulation and intimidation to keep Rita and Jane from speaking about certain matters.
