In the fourth season (1999–2000), Buffy balances her Slayer duties with her new life as a college student at UC Sunnydale. She experiences some difficulty adjusting to college life, and becomes increasingly disconnected from her friends, who all seem to be moving in different directions. Buffy eventually finds a new love interest in the form of Riley Finn (Marc Blucas), a soldier in the demon-hunting government task force known as The Initiative. She briefly joins forces with Riley's team, until they discover one of the Initiative's experiments, Adam (George Hertzberg), is creating an army of demon-human hybrids. Buffy unites with her friends to defeat Adam in a spell which invokes the power of the First Slayer. During "Buffy" season four, Buffy also appears in the first season of spin-off series "Angel" (1999–2000), guest starring in the episodes "I Will Remember You" and "Sanctuary".
