Sadie was happily married to her husband, Jake Adler, and expresses that she was content in the life they lived together. His death made her deeply vengeful, vindictive, and consumed by desire for revenge against the O'Driscolls. Sadie also repeatedly demonstrates cruelty, a lack of care for her allies and recklessness which rivals that of Micah's - she is not above putting herself and her friends in unnecessary danger. Despite this she is very loyal and can genuinely love those around her.
