 Buffy reluctantly undergoes training in her abilities by Merrick, and as her responsibility as the Slayer causes her to become alienated from her valley girl peers, she finds friendship and romance with fellow outcast Pike (Luke Perry)
 A younger sister named Dawn (Michelle Trachtenberg) mysteriously appears in Buffy's household, her existence having been seamlessly integrated with memories of the other characters
