Character mistake: Cindy tells Greg she hasn't worn curls for 12 years. This is incorrect because in the original series, she changed from curls to braids by 1973 and then to straight hair by 1974. This story takes place in 1988 so technically, she hasn't worn curls in around 15 years (not 12).
Character mistake: Mr. Phillips told Michael (Danny) that he'd like him to apply for "early admission" to Julliard. Michael was a 17-year-old high school senior and had not yet auditioned for Julliard - the audition is to occur when a student his age is "entering 12th grade in the Fall of the academic year for which he is applying." It was too late to submit an application and an "early admission" was not possible at this point. (01:08:42)
