For the most part, Moira was a kind spirit to those that returned her kindness. Vivien Harmon proved this time and again when the two formed a friendship. Moira admired Vivien's resolve during her difficult marriage. She went after Ben in the hopes that she could reveal to Vivien the kind of man she was married to. She also tried to get Vivien to leave the home, knowing that she was doomed so long as she stayed. While the family, sadly, never made it out of the house alive, the Harmons still considered Moira part of the family.
