Mallory makes her first and only appearance in If Boys Were Girls during Lois' fantasies. In it she and Renee were fighting over a pen(Like Malcolm and Reese were).

Mallory tells her that she doesn't need to be a genius because she's sweet and thoughtful. She, Renee and Daisy reconcile and are excited to go shopping with Lois. Mallory suggested that Renee and Daisy goes to the first floor to look for new clothing, while she and Lois takes the 2nd floor. They'll rendevouz at the preztel place every 45 minutes to check out what they need to get. Lois tells her, Renee and Daisy to calm down because they go to the mall everyday.

Lois tells her that she won't be offended if she wanted to have some ice cream with him. Mallory passes on it because she, Renee and Daisy wants to treat her instead. However near the end, it's revealed that he was really looking for Renee when it's revealed that she's pregnant and Mallory has a problem with her clandestine diet. Soon, she and her sisters gang up on Lois and blames her for their own problems.
