As Felicia informs Edie upon her arrival, she knows that her sister is dead and has come to Wisteria Lane to discover who is behind her sister's murder. After finding and reading Martha's journals, Felicia discovered that Martha was blackmailing Mary Alice after she discovered her secret. Incidentally, Martha found this out from Felicia, who had worked in the same rehab center as Mary Alice did back in Utah. Felicia then realizes that it was Paul who had murdered her sister as he had obviously found out that Martha was blackmailing Mary Alice. After revealing that she knows everything, Felicia tells Paul to leave town for good or she will expose Zach's true identity and the fact that he murdered Martha. Paul agrees to go but Felicia then informs him that Zach shall be staying with her from now on. When Felicia informs Zach about this, he attacks Felicia with a hockey stick which causes Felicia to fall down a flight of stairs, causing severe injury to her neck.
