what is the conflict in chapter 6 of Lizzie Bright and the Buckminister boy

The next morning, Turner is “forbidden” from going anywhere near Malaga Island. He daydreams in church as his father preaches a sermon about how important it is for a God-fearing community to do what it can “to blot out spoil and contagion from among us”. Turner wanders around the house in boredom and frustration until his mother tells him to go outside. He begins to wander towards the route to Malaga, when he’s interrupted by Mrs. Cobb, who demands that he come in and play for her. As he settles down by her old and dusty, unused organ, she tells him to take down her last words, if she should happen to die while he’s there. He agrees, and starts playing, becoming happier to do so as she starts to smile, sing along, and eventually clap.
