Her parents are divorced, having met and quickly married as hippies. After inheriting a small fortune, Trudy's mother became a shady businesswoman. Her father secretly joined the FBI over 20 years ago, and kept up his hippie guise to keep tabs on his now-ex-wife. She is now on the lam as well. Trudy thus learned not to rely on anyone but herself, shaping her selfish personality. She also has a younger sister, given up for adoption, who is in fact Sharon Murphy.
