How does Flora's plan begin to blossom for getting Amos Starkadder "out of the picture"?

Flora has a difficult time trying to get to know Cousin Amos better as the meals are eaten in virtual silence or fighting. She asks Amos if she can join him when he goes to preach at the Church of the Quivering Brethren in Beershorn and he agrees, even though he believes she is damned anyway. On the journey by buggy, Flora questions Amos about his preaching and suggests he preach to larger congregations to save more souls. Secretly, she thinks that tidying up the farm would be a lot simpler if he was on long preaching tours. At first, Amos thinks it would be vain to preach to larger crowds and says that vanity is a sin, but Flora points out it would be a bigger sin not to reach out to more than a handful of sinners. Amos is rather taken with the idea. Here, she plants some ideas in his head which will presumably produce fruit later.
