Answer:
The first scene where Tub accidentally shoots Kenny: This scene could be shocking because it involves a sudden and unexpected act of violence. Additionally, the fact that the shooter is one of the main characters could be surprising to some readers.
Kenny's behavior towards Tub after the shooting: Kenny's reaction to being shot is to make light of the situation and even poke fun at Tub for his poor marksmanship. Some readers may find this shocking or disturbing due to Kenny's seemingly callous and insensitive attitude towards his own injury.
The revelation that Frank has been cheating on his wife: This moment could be shocking to readers who have become invested in Frank's character and his relationship with his wife. Additionally, the way that Frank's infidelity is revealed (through a conversation between him and Tub) could be surprising or unexpected.
The scene where Kenny intentionally runs over Tub: This is arguably the most shocking moment in the story, as it involves an extreme act of violence and betrayal by one of the main characters. The fact that Kenny's behavior had been escalating throughout the story (including his mistreatment of dogs and his treatment of Tub after the shooting) could add to the shock value of this scene.
