Re: Dubliners - "The Sisters" (Story 1 of 15)
I think 'the sisters' represent good, piety, innocence, kindness, helpfulness etc. and so stand in counterpoint to the shrouded mystery and possible evil-doing in which Father Flynn and the boy may be involved. This creates emotional tension in the story and so is central to the narrative and, in this way, it makes sense that the title is 'The Sisters'. And perhaps Joyce wants us to think about where 'good' is found ... and where 'salvation' is found by drawing attention to 'the sisters' where otherwise they might be considered minor characters?
