It doesn't seem like much happens here. Jesus' brothers don't believe. They bait him into going to the festival. He said, "No. My time hasn't come." And, then he went. Hmmm. The temptation, that lasted from his temptation in the wilderness by Satan to his last moments on the cross, to prove himself had to be hard. He heard it all the time!
They marveled at his lack of formal education, yet the quality of his knowledge. He told his brothers that "Now was your time." That's why the world didn't hate them.
His argument from circumcision to healing on the Sabbath is an interesting one.
