In "Sauron Defeated", earlier drafts of the chapter show that Tolkien had considered giving Frodo a far more energetic part in confronting Sharkey and the ruffians. These throw light on Tolkien's choice of who Sharkey actually was, whether the "boss" hobbit Lotho Sackville-Baggins, a human leader of the gang of ruffians, or Saruman. Tolkien had thus hesitated over how to implement the "Scouring", only arriving at Saruman after trying other options. Birns argues that the effect is to bring the "consequentiality of abroad" (including Isengard, where Saruman was strong) back to the "parochialism of home", not only scouring the Shire but also strengthening it, with Merry and Pippin as "world citizens".
