Roper is Sir Thomas’s son-in-law. He is highly obedient to his father-in-law, and tries to shield his mother-in-law from worries.
He worships Sir Thomas, trading Latin tags with him, agreeing with all that he says and always remembering not only More’s wisdom but the fact that he is known to be wise. He attempts to convince Sir Thomas to sign the King’s articles with the argument that being More, he could get away with it. More’s upcoming death brings him to tears.
