Jeremy Johnson

Jeremy Johnson (Mitchel Musso) is the love interest of Candace Flynn and brother of Suzy Johnson. Whenever activities are going on in the Flynn-Fletcher Household, he goes to visit just to enjoy the activity. In an interview with Mitchel Musso, he revealed that Jeremy returns Candace's feelings for him. Also, Candace is angry about her brothers at one time, but when Jeremy comes for a visit, Candace's feelings seem to soothe.

His catchphrase is "Hello, Candace", in which she responds: "Hi, Jeremy.", and "Uh...Candace?" He works part-time at the Slushy Dog, which Candace frequents for just that reason.

One Good Scare Ought to do it

It is then revealed that he was only faking when he puts down his arms and legs and shows the food is somehow connected to him. He was just doing this to impress Candace.
