Steve Sanders is a main character introduced to find his birth parents, only to discover that his biological mother had passed away. It was revealed years later that Steve's adoption was true of only one parent, as Rush is indeed his biological father. With this information in the open, Steve and Rush finally began settling their differences for good. Rush would later help Steve start up a publication with Brandon.

It was revealed throughout the first season that Steve had a history with Kelly Taylor, which included an ultimately failed romantic relationship. It was implied that Steve's generally conceited, careless attitude at the time was what had led Kelly to leave him. Despite this, the two would remain close friends well into their adult lives.
Steve won the affections of Celeste Lundy while competing on a dating game show, and began seeing her soon afterward. Though he cherished the relationship, Steve lost Celeste following an irresponsible moment in which he became unfaithful. However, the two regained a portion of their friendship while spending time together at a carnival.
Steve would later begin a long-term involvement with the semi-snobbish Clare Arnold. While largely playful at first, both would gradually reveal more mature and sensitive sides through their dedication and love for one another. In contrast to his high school relationship with Kelly, Steve displayed more restraint during arguments with Clare; he was generally less cocky and more interested in compromise. This would often help to reinforce the genuine affection that existed between the two. At the end of their relationship, Clare reluctantly left Steve and Beverly Hills to spend time with her distraught father.
Steve was later involved with a woman named Carly Reynolds and developed a fatherly bond with her young son, though they eventually moved away as well.
Steve finally met 'the one' in Janet Sosna, (portrayed by Lindsay Price) an emotionally guarded woman who worked on the Beverly Beat publication and initially wanted a merely sexual relationship with him. In time, however, the pair would come to realize and acknowledge their true feelings, and developed a deeper bond that resulted in marriage and the birth of their daughter, Madeline. Thus, Steve concluded the series as a loving husband and father.
- Steve also made brief guest appearances in early episodes of Melrose Place, the franchise's second series, accompanying his friend Kelly Taylor to Los Angeles (while joined by Donna Martin and David Silver).
