Jesse Katsopolis, affectionately known to all as Uncle Jesse, was a bit of a player when Full House premiered in 1987, but that all changed when he met Rebecca Donaldson, "Aunt Becky," early on in the series. Jesse and Becky's relationship was a major storyline over the course of the ABC sitcom's eight seasons (and later in the Netflix sequel television series Fuller House). Although they experienced a few ups and downs, the couple had a strong foundation that ultimately led to a formidable romance.
