Fox is the son of Ivy Winthrop and Julian Crane. While growing up, Fox felt ignored by his mother, who favored his older brother, Ethan. Fox bounced around several boarding schools before settling down in Harmony. The former playboy changed his mischievous ways once he met Whitney Russell. However, the relationship fell apart due to her many deceptions. The charming and sarcastic young man then fell madly in love with Kay Bennett. The return of Miguel Lopez-Fitzgerald – Kay’s life-long crush and the father of her baby – has brought out Fox’s darker side.
