The nobleman begged Jesus to come down and heal his son, and Jesus answered, "Unless you people see signs and wonders, you will in no way believe" (4:48). Was Jesus turning him away?

Here is what John tells, in order. The nobleman "went to him and begged him that he would come down and heal his son, for he was at the point of death" (4:47). "Jesus therefore said to him, “Unless you people see signs and wonders, you will in no way believe.”" (4:48). The WEB has you people, and in Greek the verbs see and believe there are plural. John doesn't say whom Jesus meant by you people, or how the nobleman took the words. He tells what the nobleman said next, "Sir, come down before my child dies" (4:49), and what Jesus said, "Go your way. Your son lives" (4:50). Then "The man believed the word that Jesus spoke to him, and he went his way" (4:50). These notes add nothing to his words.
