I'd argue the opposite, but it's really just preference; I think that the teasing of other candidates (Murphy and Susan briefly, then Butters permanently) points to the final Sword falling to a Carpenter. The twist would be that it was the one least expected, the Dutiful Daughter Amanda rather than the more prominent ones, like the youngest children and Daniel. I could buy Hope, if only because her nickname is Hobbit, too.
I'm one of the few who wouldn't be particularly happy if Thomas or Marcone wound up as a Knight.
