Trish is fun-loving, lazy, selfish, and sometimes sarcastic. She is constantly getting hired and then fired from job after job because she does not apply herself, dislikes work, and is often not there to work, has a lack of effort and responsibilty, and uses the items from her jobs for selfish use, and her parents force her to get a job because of irresponsibilty. She is Ally’s best friend and Austin’s manager. Even though her wild schemes sometimes lead to trouble, she can always count on her friends to help her out of any kind of jam.

Trish mixes up Ally's song lyrics, getting the wrong props for a music video, and has to worry about Face Puncher punching her in the face for accidentally ruining his jacket.
Trish wants Ally to get revenge on Austin for reading Ally's diary, which she forced out of Dez by eating his gingerbread man...
