After Franziska pushed Boatman into a holding cell, Margot told her the truth about the subliminal motives behind her and Boatman's actions, telling Franziska that her motive was a demonic obsession with Judge Evans. Franziska then became unhinged and charged at Margot, but Edgeworth pinned her down and calmed her down. He told Franziska that Margot was right and that he was the one who ended up in the wig shop, and he then threatened to leave Franziska behind, claiming she was just a "big, fat liability". However, Franziska then broke down in tears and told him that she had no reason to want to keep her alive and she could see that she and Margot were different and that they could become good friends. Edgeworth then told Franziska that he was angry with himself, and he stayed behind with her while the rest of the team went to see Judge Evans.
During police investigations of the homicide victims, Fey was briefly considered as a suspect in the case when investigators unearthed documents that indicated she was jealous of Stella, believing that she had been hired to replace her. However, Fey never held a grudge against Stella because she was a twin and Fey had never been able to compete with her for the attentions of Wright. In addition, after finding out about the whispers that Wright was having an affair with a married woman, Fey was actually on the verge of forgiving him. The only problem was that Fey herself was secretly having an affair with Margot.
After Edgeworth was forced to reevaluate his beliefs, the pair had a private conversation and Fey gave him the documents she had found after the murder. However, the duo did not hear from each other after that. In January, 2011, Edgeworth visited Fey at Hotti's, where she told him that she had been helping Margot with the investigation in the Amnesia case. She also asked Edgeworth to help her with the case. Later, she showed up unannounced at Edgeworth's home to apologize for whatever she did to him. d2c66b5586
