what is ethane plan for the broken dish, and how does he feel

Ethan's plan is to buy another dish if he can find one or simply put the pieces back together. He doesn't seem overly worried (except about Mattie).

"Without replying he gathered the pieces of glass into his broad palm and walked out of the kitchen to the passage. There he lit a candle-end, opened the china-closet, and, reaching his long arm up to the highest shelf, laid the pieces together with such accuracy of touch that a close inspection convinced him of the impossibility of detecting from below that the dish was broken. If he glued it together the next morning months might elapse before his wife noticed what had happened, and meanwhile he might after all be able to match the dish at Shadd's Falls or Bettsbridge. Having satisfied himself that there was no risk of immediate discovery he went back to the kitchen with a lighter step, and found Mattie disconsolately removing the last scraps of pickle from the floor."
