Imagine being Thorin’s human wife, the Queen of Erebor. Dis is not accepting you because of your race and making vicious comments about it everytime you see each other. One time she points out that you have problem with getting pregnant and you cannot give Thorin a heir. You loose your patience and, ignoring the fact that she is Thorin’s sister, scream at her, showing her place as you are her queen and ‘she should shut the  fuck up already’. She never makes a mean comment again.
