Watch the painful movement of John 6.
Jesus feeds 5,000 plus. This scene crescendos in verse 15 as the crowd begins to move to make Him King. He ducks out and later walks on water.
Then! Then Jesus makes an off-putting speech about flesh-eating and blood-drinking. Many of those following Him leave. He turns to the twelve and gives them the opportunity to exit too.
Then, while they are professing their allegiance, begrudgingly, Jesus prophecies that one of them will betray them. Not just leave; Betray. Not desertion; opposition.
So, in one chapter Jesus moves from almost being made King by force, so passionately did the crowds feel for Him. By the end of the chapter the crowd was leaving Him, and they were upset. Not only that but He voices the realization that one of His twelve is going to turn against Him.
