From the start of Aly's run on "The Bold and the Beautiful," fans could see that she was troubled. Losing her mother in a car accident caused by Taylor Hayes (Krista Allen) was already a tough pill to swallow, but finding out that her father was engaged to Taylor was too much for Aly to take. She attacked Taylor with an ax when her father told her the news; not quite the happy reaction they were expecting. She eventually gave them her blessing for their marriage, but things on soap operas are not always as they seem.

On the outside, Aly seemed to be getting by; on the inside, she was growing increasingly erratic. On top of lying about her forgiveness for Taylor for killing her mother, Aly had been having visual and auditory hallucinations of her mother telling her what to do. Spurred on by her mother, Aly harbored growing hatred for Taylor and her coworkers at Forrester Creations. She was especially hostile toward Steffy Forrester (Jacqueline MacInnes Wood), whom she was jealous of and scared her boyfriend would cheat on her with.
