What do Mattie and Ethan talk about on the walk home from town?

Mattie and Ethan speak about the possible wedding rumors circling around Mattie and Denis, and Zeena's thoughts that she might need to hire a new girl. Their banter is rather flirtacious, but Mattie alludes to never wanting to leave Zeena or Ethan..... Ethan is thrilled and excited by her words and puts his arm around her.
