In fact, something common in the Throne family is that not all of them see and accept what is real in a way. Everyone knows that Mary uses morphine, but nobody does anything for her, everyone knows Edmund is sick but they don’t give enough attention to him or any effort. Everyone knows that Jamie is failing on his carieer, but nobody gives reason to be better. Everyone knows that Mr. Throne is stingy and that his wife needs love, but nobody tells him that he should do more. Everyone blames each other and nobody comes up with solutions, which kills the family's need to "feel family". Nobody feels like home because nobody helps each other.
The most important feature of a family concept is to keep the family together, to help and support each other's problems. Like the organs of a body, the purpose is to keep the heart of family alive. But none of these features are found in the Throne family. They are the family which dies due to their past tragedies and does not try to breathe, and constantly blame on each other. Because actually the tragedy of someone in the family is the tragedy of everyone in the family. If you are a character who does not support to heal this tragedy, then it means you also are dying with your family in that tragedy.
