In this season-finale story arc, the team is splintered literally and metaphorically after a confrontation with the Soul Glutton and the Mistress. As Buffy searches for ways to bring the team back together, insecurities plague her budding relationship with Spike. Seems like a great time for a new Big Bad to make a move to capture the Vampyr book and rewrite the rules of magic. When the stakes grow perilous, Buffy must trust in herself to make the right choice and bear the burden of protecting the book from the monsters who wish to abuse it.
