frank is the only one who knows abt ally and surprise surprise frank is also Ally's friend bc he and wally are the only ones who can see her while shes invisible sometimes frank and wally hang out w/ her but only in Home so no one suspectes them
did you know Ally was kicked out of Home by the producers bc she knew too much? now she just sits on wally's shoulder during the show and during break time or after the show she flirts w/ him lol
