The spot where Lizette is stopped and Will rides up to bring her lunch is the exact spot where Murphy and Moses stop for lunch (after leaving Gold Hill in the early morning) in the season 1 episode "Matthew and Elizabeth." In that scene. they have been riding for hours and stop for lunch under that tree, unknowingly having Matt and Elizabeth in the back. Yet here in "Buttons and Beaux", Lizette is able to walk from Gold Hill to this location on her way to Jackson to work.
