Before joining The Order, Scully had been in the military and given an honorable discharge for "failing to obey a military order". Scully speaks with a brassy, boisterous voice and is deeply empathetic and caring towards others. She becomes a good friend of Roslyn Davenport's and eventually fights by her side.
Like Roslyn, Scully can also be brash and have a "no nonsense" attitude. She enjoys socializing but doesn't like gossip or smack talk. Her morals are the pillars of her character, which she sticks to whether or not it could lead her to break rules.
